Directed IPv6 PING messages were being transmitted from other interfaces
if the specified interface was down. This issue has been resolved.
PCR: 03663
Module: SWCX
Level: 2
When CAM segments were full, the CAM entries were not being moved
correctly, and occasionally corrupting on compaction. This issue has been
resolved.
PCR: 03668
Module: SYSR
Level: 2
The SHOW SYS SYSR SLAVE command did not return a list of valid
features. This issue has been resolved.
PCR: 03686
Module: IPX
Level: 3
Entering the SHOW IPX CACHE command on the SwitchBlade or AT-9800

Patch Release Note
PCR: 03524
Module: OSPF, IPG
Level: 2
The SET VLAN BCLIMIT command did not work when executed from
start-up in a configuration script. This issue has been resolved.
PCR: 03717
Module: IP, SWCX
Level: 2
New static routes cannot be added to the forwarding database until ARP
has resolved the routes' next hop MAC address. In the meantime, selecting
the best alternative route was sometimes causing incorrect forwarding and
loops. To avoid this situation, packets destined for dead-end routes are now
forced to the CPU. The CPU then creates an ICMP_Redirect message to the
source of the unforwardable packet to remove the previous hop from its
routing table.
In order to force packets back to the CPU, the hardware MAC table contains
a special entry for each VLAN that maps the unused MAC address
55.55.55.55.55.55.55.55 to the Multicast Group ID 4096. When the switch
encounters an unknown next hop MAC address, it now sends the packet to
the L2MC Group 4096. Because this group does not exist, the packet is
forwarded to the CPU. Note that this process will increment the SHOW
SWITCH COUNTER command’s L2MCGroupSoesntExist counter.
PCR: 03726
Module: TTY, USER
Level: 3
When a user logged on twice, thus creating two sessions, the user log on
time for the second session was overwriting the value recorded for the first.
This issue has been resolved by displaying the log on times as two separate
sessions.
PCR: 03727
Module: SWI, STP
Level: 2
Previous STP ports were not being deleted correctly when line cards were
hot swapped. Also STP ports were not initialising correctly when STP was
not enabled. These issues have been resolved.
PCR: 03734
Module: IPG
Level: 2
With static multicasting enabled on two VLANs, only the first few multicast
packets of a stream were L3 forwarded. This issue has been resolved.
PCR: 03736
Module: IPG
Level: 3
The copying of switch routes between internal components was causing
processing delays. This issue has been resolved.
PCR: 03739
Module: SWI
Level: 2
Although the SwitchBlade hardware is capable of forwarding jumbo
frames, sending these to the CPU was causing a variety of issues. These
issues have been resolved.
PCR: 03746
Module: BGP
Level: 3
Attempts to disable BGP debug were, depending on configuration,
resulting in either a system failure, or the debug messages continuing to
appear after debug had been disabled. This issue has been resolved.

Patch SB251-13 For SwitchBlade 4000 Series Switches and AT-9800 Series Switches
5
PCR: 03747
Module: VRRP
Level: 3
An unknown interface log message was returned for VRRP if there was an
interface UP or interface DOWN event due to a mismatch between a
monitored interface index and the corresponding interface instance. This
issue has been resolved.
PCR: 03751
Module: MLDS
Level: 3
The MLD snooping entries registered on a port were not removed when the
port went down or was unplugged. This issue has been resolved.
PCR: 03764
Module: IPG
Level: 3
The IP multicast counter did not increment when IGMP, DVMRP and PIM
packets were transmitted and received. This issue has been resolved.
PCR: 03769
Module: SWI
Level: 2
An error occurred in the GUI if it had been in operation for more than 20
days. This issue has been resolved.
PCR: 03778
Module: FILE, INSTALL, SCR
Level: 2
Files used during start up were backed up from NVS to FLASH even if they
were already present in FLASH. This used up FLASH memory
unnecessarily. This issue has been resolved so that files are only backed up
when a copy does not already exist in FLASH.
PCR: 03780
Module: INSTALL
Level: 3
If a configuration file had a long file name, the SHOW CONFIG command
displayed the file name using the shortened DOS 8.3 format (where file
names are 8 characters long, with extensions of 3 characters). This issue has
been resolved so that long configuration file names are now displayed using
the DOS 16.3 format (where file names are up to 16 characters long).
PCR: 03783
Module: IPG
Level: 3
The TIMEOUT and SIZE parameters are only valid for the SET IP DNS
CACHE command, but no error message was returned if either parameter
was specified for the SET IP DNS command. This issue has been resolved.
PCR: 03784
Module: IPV6
Level: 3
Fragmentation of IPv6 packets now complies with RFC 2460’s requirement
to align packet sizes to 8 octets.
PCR: 03791
Module: SWCX
Level: 2
Disabled copper ports on AT-SB4411 8-Port (RJ-45) Gigabit Ethernet Line
Cards and AT-SB4441 8-GBIC Line Cards were not disabled on reboot. This
issue has been resolved.
PCR: 03793
Module: RSVP
Level: 3
The ENABLE RSVP INTERFACE command did not succeed if IP was
enabled after the RSVP interface had been created. Now, ENABLE RSVP
INTERFACE will succeed regardless of when IP is enabled as long as an IP
interface exists.

Patch Release Note
PCR: 03795
Module: SWI
Level: 3
Browsing the dot1dTpFdbPort table with SNMPv2c sometimes gave
incorrect output. This issue has been resolved.
PCR: 03796
Module: STP
Level: 2
Setting RSTPTYPE to NORMAL, when normal has already been set, sets all
ports to the “sending RSTP” state process. This is referred to in IEEE 802.1w
as mCheck.
When RSTPTYPE was changed from STPCOMPATIBLE to NORMAL with
the SET STP command, the STP instance continued to send STP BPDUs
until an mCheck was performed by entering the SET STP
RSTPTYPE=NORMAL command again. This issue has been resolved so
that when RSTPTYPE is set to NORMAL an mCheck is performed, causing
the STP to start sending RSTP BPDUs immediately.
PCR: 03800
Module: LOAD
Level: 2
If a DNS lookup failed when using the UPLOAD command to load a file
with a host name, the file was sometimes deleted from FLASH. This issue
has been resolved.
PCR: 03801
Module: MLDS
Level: 2
MLD and MLD Snooping accepted MLD Query packets with a hop limit
greater than 1. Duplicate packets were forwarded when the hop limit was
not 1 and the payload was 0::0. This issue has been resolved. MLD and MLD
Snooping now require the hop limit to be 1.
PCR: 03802
Module: FIREWALL
Level: 1
Packets with bad ACK numbers were sometimes generated by the firewall
as part of the proxy TCP setup process. These packets sometimes caused
TCP sessions from the public side of the firewall to fail. This issue has been
resolved.
PCR: 03806
Module: VRRP
Level: 4
After the SHOW VRRP command was executed, incorrect trigger messages
were entered into the log. This issue has been resolved.
PCR: 03811
Module: UTILITY
Level: 2
A fatal error sometimes occurred when using hardware filters if DMA
debug was enabled. This issue has been resolved.
PCR: 03813
Module: SWI
Level: 2
Rate limiting sometimes prevented IGMP snooping and MLD snooping
from operating correctly. This issue has been resolved.
PCR: 03814
Module: SWI
Level: 1
A fatal error occasionally occurred because of an error with internal
processing of the control blades. This issue has been resolved.
PCR: 03815
Module: SWI
Level: 3
The SHOW SWITCH HOTSWAP command output displayed more than 4
blades on a 4 blade chassis. This issue has been resolved.

7
PCR: 03817
Module: IPV6
Level: 2
A fatal error occurred when IPv6 fragmented a packet. Also, when a large
fragmented ICMP echo request packet was received, the reply may not have
been fragmented and so may have exceeded the MTU for the interface it
was sent on. These issues have been resolved.
PCR: 03819
Module: SWCX
Level: 3
Previously, Multicast Storm Protection limited broadcast packets when
Broadcast Storm Protection was not enabled. This has been changed so that
only multicast packets are limited when Multicast Storm Protection is
enabled, and only broadcast packets are limited when Broadcast Storm
Protection is enabled.
PCR: 03821
Module: SWCX
Level: 3
If a 10MB half-duplex link was connected to a port, the maximum
bandwidth shown in the SHOW SWITCH TABLE command output was not
updated. This issue has been resolved.
PCR: 03823
Module: VLAN
Level: 2
If the last port in a VLAN went down, that port was not automatically
deleted from IGMP groups. This issue has been resolved.
PCR: 03824
Module: IPG
Level: 3
A multihomed interface sometimes sent duplicate multicast packets. This
issue has been resolved.
PCR: 03825
Module: IPG
Level: 2
The incorrect logical interface was selected for broadcast packets received
with a subnet mask that differed from the class mask. This issue has been
resolved.
PCR: 03826
Module: BGP
Level: 2
When BGP imported routes from IP with the ADD BGP IMPORT command,
and there were multiple import choices, the best IP route was not always
imported. This issue has been resolved.
PCR: 03828
Module: IPV6
Level: 2
The MTU value for IPv6 PPP interfaces was always set to 1280 bytes. This
MTU value is now correctly set to 1500 bytes, and 1492 bytes for PPP over
Ethernet (PPPoE).
PCR: 03829
Module: SWCX
Level: 3
The value of the ifInErrors counter in the SHOW INTERFACE=interface
command incorrectly showed the number of packets received with bytes in
the normal range. This issue has been resolved. The ifInErrors counter now
correctly shows the number of packets received that had errors.

accepted by the ADD SWITCH HWFILTER command when added in a
particular order. This issue has been resolved.
PCR: 03835
Module: VLAN
Level: 3
If either the MCLIMIT or BCLIMIT parameter in the SET VLAN MCLIMIT
BCLIMIT command was set to NONE, the other parameter was sometimes
incorrectly set to NONE as well. This issue has been resolved.
PCR: 03836
Module: OSPF
Level: 2
OSPF sometimes chose routes with an infinite metric over routes with a
finite metric when selecting the best local route. This issue has been
resolved.
PCR: 03837
Module: VLAN
Level: 3
When browsing the ifInNUcastPkt MIB counter, the value was not correctly
incremented because only broadcast packets were counted. This issue has
been resolved.

being unaware of the IPv6 interfaces it was running on. This issue has been
resolved.
PCR: 03843
Module: DHCP
Level: 2
When some DHCP entries were in Reclaim mode, and all interface links
related to the range of these entries went down, these DHCP entries were
stuck in Reclaim mode. This issue has been resolved.
PCR: 03846
Module: SWCX
Level: 2
An STP blocking port did not discard SNAP encapsulated packets with
TYPE=00BB (ESRP packets). This caused a loop in the network. This issue
has been resolved.

switch. This issue has been resolved.
PCR: 03864
Module: BGP
Level: 2
BGP sent Update packets when the local host route table changed but did not
affect BGP. Also, BGP did not send Withdrawn packets when there was a
change in the best route. These issues have been resolved.
PCR: 03865
Module: FIREWALL
Level: 2
When dual firewall policies were defined, public to private passive mode
FTP transfers sometimes failed. This issue has been resolved.
PCR: 03867
Module: BGP

PCR: 03880
Module: SWICX, SWI
Level: 2
Uplugging the remote receive port on the 32FX card (AT-SB4352) was
causing the switch to lock-up. This issue has been resolved.
PCR: 03887
Module: SWCX
Level: 2
When the speed and duplex settings of a port were configured with the SET
SWITCH PORT SPEED command, the port sometimes erroneously
advertised auto-negotiation capabilities, usually when ports were
configured with a startup script. This issue has been resolved so that switch
ports will not advertise any capabilities when configured with fixed speed
and duplex settings.
PCR: 03888
Module: DHCP, TELNET
Level: 2
When the device was configured as a DHCP server, a fatal error sometimes
occurred when a Telnet session to the device was closed while DHCP was
reclaiming IP addresses. Also, a Telnet error message displayed an incorrect
value when a telnet command line parameter was repeated (for example,
SHOW TELNET TELNET). These issues have been resolved.
PCR: 03889
Module: IPV6
Level: 2
Packets were not routed when an IPv6 flow was enabled. This issue has
been resolved.
PCR: 03890
Module: IGMP, SWI
Level: 2
The switch was adding a router port for multicast packets to destinations
with an address in the range 224.0.0.x. Switch port entries are now only
created for special router multicast addresses.
PCR: 03891
Module: CORE
Level: 3
When the configurable temperature threshold had not been set, its value
should show as “Undefined” in the output of the SHOW SYSTEM
command, but it showed the same value as the fixed temperature threshold.
This issue has been resolved.
PCR: 03899

A fatal error occurred with NVS when the log contained too many debug
log messages. These messages were added with PCR 03701. This issue has
been resolved.
PCR: 03921
Module: IP, ARP
Level: 2
The switch was previously responding to ARP request packets received
with invalid (i.e. broadcast or multicast) source MAC or IP addresses. This
issue has been resolved so that ARP packets received with broadcast or
multicast MAC or IP addresses will be discarded.

issue has been resolved.
PCR: 3956
Module: SWI, CORE
Level: 2
On an AT-9800 with certain third party GBICs, running the restart reboot
command would cause the switch to lock-up. However the problem did not
occur when using the Reset button. This issue has been resolved by
disabling all ports before performing a RESTART REBOOT.
PCR: 03965
Module: IPSEC
Level: 2
IPv6 was using the same SA (security association) soft expiry timer at both
ends of link. This was wasting CPU and memory resources. This issue has
been resolved.
PCR: 03966
Module: MLDS
Level: 2
A multicast listener discovery (MLD) snooping entry was incorrectly added
to the SwitchBlade’s layer two multicast address table.
The AT-9800 was not adding layer two MLD Snooping when additional
VLANs were created.
The failure of a SwitchBlade port was causing restarts due to the switch
attempting to remove the port from a “non existent” MLD Snooping list.
These three issues have been resolved.
PCR: 03968
Module: OSPF
Level: 2
Large routing areas, containing many hosts and interfaces, were causing
fatal errors due to the excessive number of link state advertisements
generated. This issue has been resolved by limiting the combined number
of routers and hosts within each area to 100.

Patch Release Note
BIST failures were occurring because the software was not full supporting
the SwitchBlade 8 port 1000BASE-LX line card 1 (AT-SB4462). This issue has

Level: 2
STP was not being handled correctly when hot swapping line cards. This
resulted in links other than the preferred link being selected.
Also, when a layer two data stream was forwarded from one line card (the
source card) to another (the destination card) via the preferred STP link, if
the destination card had been swapped out, and the backup link was via the
source card, then the data stream would not be forwarded correctly over the
backup link.
These issues have been resolved.

Patch SB251-13 For SwitchBlade 4000 Series Switches and AT-9800 Series Switches

Multicast Listener Discovery Snooping
Multicast Listener Discovery (MLD) snooping enables the switch to forward IPv6
multicast traffic intelligently, instead of flooding it out all ports in the VLAN.
Without MLD snooping, multicast group membership for VLAN aware
devices is on a per-VLAN basis, because MLD is an IPv6-based protocol. If at
least one port in the VLAN is a member of a multicast group, and MLD
snooping is not used, IPv6 multicast packets will be flooded onto all ports in
the VLAN. With MLD snooping, the switch passively listens to MLD joins /
reports and leaves / done messages, to identify the switch ports that have
received joins and/or leaves from devices attached to them. Multicast traffic
will only be forwarded to those ports. MLD snooping will also identify ports
that are connected to another router or switch and forward messages out those
ports appropriately.
MLD snooping is performed at Layer 2 on VLAN interfaces automatically. By
default, the switch will only forward traffic out those ports with routers or IPv6
multicast listeners, therefore it will not act as a simple hub and flood all IPv6
multicast traffic out all ports. MLD snooping is independent of the MLD and
Layer 3 configuration, so an IPv6 interface does not have to be attached to the
VLAN, and MLD does not have to be enabled or configured. MLD is described
in the “IPv6 Multicasting” chapter of the AT-9800 Series Switch Software
Reference.
MLD snooping will not generate MLD query messages, but will relay MLD
queries from other routers or switches attached to one of its ports to other ports
in the same VLAN.
MLDv2 supports Multicast Address and Source Specific messages. These
messages enable a host to listen to traffic from a particular source to a
particular multicast address, instead of all traffic for the group. MLD snooping
cannot snoop these messages, because the address information is contained
within the packet’s IPv6 Layer 3 header. These messages will be flooded to all
ports in the VLAN. The switch will snoop MLDv1 message types 130 (Query),
131 (Listener Report) and 132 (Listener Done), as specified in RFC 2710,
Multicast Listener Discovery (MLD) for IPv6, October 1999.
Multicast group membership registration entries on the switch will time out
after no data or messages have been received for that group on that port for 270
seconds.
The following multicast addresses are used by IPv6 for special purposes, and
will always be flooded:
FF02::1 (All nodes)
FF02::2 (All routers)
FF02::4 (DVMRP)
FF02::5 (OSPFIGP)
FF02::6 (OSPFIGP Designated routers)
FF02::9 (RIPv2)
FF02::d (PIM)
FF02::f (CBT)
FF02::12 (VRRP)

Patch Release Note
MLD snooping on the switch uses the last 4 bytes of the IPv6 address to
distinguish multicast addresses. It is therefore unable to distinguish different
multicast addresses that end with the same 4 bytes. Creating an entry for a
multicast group will have the effect of creating an entry for all groups with
addresses that end with the same 4 bytes as that group’s address. For example,
traffic for the groups:
ffxx xxxx xxxx xxxx xxxx xxxx 1234 5678 and
ffyy yyyy yyyy yyyy yyyy yyyy 1234 5678
will be forwarded out the same set of ports, irrespective of the values of x and
y. Therefore, if MLD snooping is used, no two groups within the multicast
domain should be given an address that ends in the same 4 bytes.
Similarly, all addresses beginning with ff02 and ending with any of:
0000:0001, 0000:0002, 0000:0004, 0000:0005, 0000:0006,
0000:0009, 0000:000d, 0000:000f or 0000:0012
will be flooded out all ports in the VLAN, because MLD snooping cannot
distinguish them from IPv6 special addresses. These addresses should be
avoided if MLD snooping is used.
MLD snooping is enabled by default. To disable it, use the command:
DISABLE MLDSNOOPING
Note that IPv6 multicast packets will flood the VLAN when MLD snooping is
disabled. Disabling MLD snooping may be useful on Rapier i Series Switches if
filters are used extensively, because MLD snooping uses a Layer 3 filter. When
MLD snooping is disabled, this filter becomes available. See “Hardware Packet
Filters” in the Switching chapter of the Software Reference for information
about filters.
To enable MLD snooping, use the command:
ENABLE MLDSNOOPING
MLD snooping can only be enabled if a free filter entry is available.
To display debugging information, use the command:
ENABLE MLDSNOOPING DEBUG
This command displays the ports that are currently receiving MLD packets and
the ports that are being added or taken off the switch’s multicast group
membership registration.
To disable debugging, use the command:
DISABLE MLDSNOOPING DEBUG
To display information about MLD snooping, use the command:
SHOW MLDSNOOPING [COUNTER]
Example output from the SHOW MLDSNOOPING command is described in
Figure 1 on page 17 and Table 1 on page 18. Example output from the SHOW
MLDSNOOPING COUNTER command is described in Figure 2 on page 18
and Table 2 on page 18.

Patch SB251-07 includes all issues resolved and enhancements released in
previous patches for Software Release 2.5.1, and the following enhancements:
PCR: 03399
Module: STP, SWI
Level: 1
With this enhancement:
•
•
STP and Port Trunking now work together correctly.
BDPU Forwarding is implemented. The BPDU Forwarding feature
configures the switch to forward all received STP BPDUs. Under
normal circumstances, the switch will not forward any received STP
BPDUs, even if STP is enabled.
This implementation is for standard STP, it does not guarantee that RSTP
and port trunking will work correctly together in all situations.
STP does not update the pathcost for trunked ports, which means that a
trunk group has the same pathcost as a single port. This may cause STP
Blocking where it is not expected. To overcome this, the user should
explicitly set the pathcost for the trunk group ports to be less than the
default value for a single port.
STP reconfigures if the Master port in a trunk group goes link down. If the
Master port in a trunk group goes link down, and a Non-Master port is still
link-up, then STP will go through the Listening>Learning>Forwarding
reconfiguration on the new Master port. This means that there will be a
switching outage on the trunk group whilst the new Master port transitions
to the Forwarding state.
Command handler changes:
•
The PORT parameter of the CREATE SWITCH TRUNK PORT and ADD
SWITCH TRUNK PORT commands must specify ports that have
identical STP port configurations.
•
The ENABLE STP and ENABLE STP PORT commands cannot be used
to enable STP operation on a port that has been disabled from STP
operation because of Port Trunking. Only the Master port in a trunk
group actively participates in the STP algorithm. Non-Master ports in
the trunk group are in the STP Disabled State.
•
The output for the SHOW STP PORT command has been modified so
that Non-Master Ports in a trunk group do not take part in the STP
algorithm.

•
The output for the SHOW STP PORT command has been modified so
that it displays whether a user has set the PATHCOST value, or if it was
auto-configured.
•
•
The PORT parameter of the SET STP PORT command specifies either all
the ports in a trunk group, or none of the ports in a trunk group.
The STPFORWARD parameter has been added to the ENABLE
SWITCH and DISABLE SWITCH commands. If STPFORWARD is
enabled, and there is no enabled STP instance, then the switch will
forward all received BPDUs. If STPFORWARD is enabled, and an STP
instance is enabled, then STPFORWARD will be disabled by default and
a message will be generated.
•
The SHOW SWITCH command now shows the status of the BPDU
Forwarding feature.

An enhancement has been made to the Test module to optimise the

Patch SB251-03 includes all issues resolved and enhancements released in
previous patches for Software Release 2.5.1, and the following enhancements:
PCR: 02361
Module: SWI
Level: 4
The SwitchBlade mirror port field on the second instance of a switch chip
was displaying as though it was the first instance. For example, if 2.26 was
configured as the mirror port, the GUI mirror object would return 2.2. The
first chip instance was not affected. This issue has been resolved.
PCR: 02527
Module: TCP
Level:3
TCP6 did not send a TCP Reset message under some circumstances, for
example when the Telnet server was disabled. This issue has been resolved.
PCR: 03025
Module: GUI
Level:2
A buffer address was incrementing and not returning buffers for reuse
when the command line interface was accessed via the GUI interface. This
issue has been resolved.
PCR: 03055
Module: SWI
Level: 4
If the SET SWITCH BLADE command was executed with the default
settings, then the default settings were added to the configuration file. The

Patch Release Note
SET SWITCH BLADE settings are now only added to the configuration file
if they differ from the default settings.
PCR: 03060
Module: CORE, SWI
Level: 3
Support has been added, to the MIB-2 interface MIB, for the port interface.
This means that port counters can now be shown.
PCR: 03066
Module: SWI
Level: 2
If a hardware filter was added to the switch, with a source VLAN and a
destination port of 1, then a host connected to the switch could not PING a
host on a different port. This issue has been resolved.
PCR: 03071
Module: CORE
Level: 2
An unexpected restart that occurred when upgrading a SwitchBlade from
Release 2.4.4 to Release 2.5.1 was caused by NVS generating an SNMP trap.
This issue has been resolved.
PCR: 03079
Module: IPG, SWI
Level: 1
Static routes were occasionally not added to all hardware tables across all
instances. This would affect connectivity if an instance had a default route
added to its table that pointed out one of its ports. This issue has been
resolved.
PCR: 03088
Module: SWI
Level: 2
Ports could not be added to the default VLAN after a hotswap, if the default
VLAN was Protocol, Subnet, MAC address, or Limited protocol based. This
issue has been resolved.
PCR: 03105
Module: FIREWALL
Level: 3
Incorrect handling of TCP sessions, and poor load balancing performance
could be caused by TCP virtual balancers not selecting a new resource if
required. This issue has been resolved.
PCR: 03112
Module: IPV6
Level: 3
The ADD IPV6 ND command now has a PORT parameter which means that
it can be associated with the VLAN parameter.
PCR: 03118
Module: CORE
Level: 4
Changes have been made to the SysDescription.
PCR: 03119
Module: CLASSIFIER
Level: 4
TCP source and TCP destination ports were swapped when viewed in the
GUI. This issue has been resolved.
PCR: 03138
Module: SWI
Level: 2
Packets that were sent out a default route could have an incorrect source IP
address, if the interface route to the destination IP address existed but was
down. This issue has been resolved.
PCR: 03141
Module: IPG
Level: 3

Patch SB251-13 For SwitchBlade 4000 Series Switches and AT-9800 Series Switches
63
Packets could be sent with an incorrect source address if a route was added
to a VLAN and another VLAN had an IP interface configured that was in
the same subnet as the route. This issue has been resolved.
PCR: 03142
Module: SWI
Level: 1
If a BIST was run at low temperatures, for example 5 or 10 degrees Celsius,
on a G8 card, then a watchdog timer restart could occur. The switch now
checks for the real course of the external interrupts that occur when running
BIST.
PCR: 03148
Module: IPG
Level: 3
If the Gratuitous ARP feature was enabled on an IP interface, and an ARP
packet arrived, (either ARP request, or reply) that had a Target IP address
that was equal to the sender’s IP address, then the ARP cache was not
updated with the ARP packet’s source data. This issue has been resolved.
PCR: 03191
Module: SWI
Level: 1
If two line cards were inserted in quick succession, then a software restart
could occasionally occur. This issue has been resolved.
PCR: 03192
Module: SWI
Level: 2
When the Built-In Self Test was run, a fault would occasionally be reported
which said that a MAC address was not learnt during the loopback test. The
ports in the BIST loopback test now remain in loopback.

If a port belongs to an enabled STP instance, but the port has been disabled
from STP operation with the DISABLE STP PORT command, the port will
not respond to ARP requests. This patch implements a workaround that
allows disabled STP ports to respond to ARP requests.
