Accessing the Brocade CEE Switch
After you log on to the switch, you can access the commands through a serial terminal port or a
Telnet session. When you Telnet into the switch, you are prompted to enter a login name and
password. When you log on to a switch supporting CEE, all of the 10 Gbps ports are disabled and
must be enabled. Refer to the Fibre Channel over Ethernet Administrator’s Guide for information
regarding feature configuration and management procedures.
Following is an example of logging in to a switch supporting FCoE and CEE.

L2 ACL commands
Use Layer 2 Media Access Control (MAC) list commands to do the following:
•
•
•
Identify traffic based on the MAC-addresses, such as VLAN IDs and different encapsulations.
Configure multiple access-lists or rules and store them in a configuration.
After you apply the access list either to an interface, a Virtual TeletYpe (VTY), or through a
command using the access-list keyword, it becomes effective.
Following are the two types of access list commands:
•
Standard Access Control Lists
Standard Access Control Lists filter the traffic on a source address and block traffic close to a
destination. There are exceptions when the address in a standard access list is not a source
address. When using a Telnet session, for outbound VTY access lists, the address in the
access list entry is used as a destination address instead of a source address.
•
Extended Access Control Lists
Extended Access Lists block traffic based on any given packet attribute. Use Extended access
control lists to test source and destination addresses and other IP packet data, such as
protocols, TCP or UDP port numbers, type of service and to provide Reflective access-lists and
Time-based access-lists.capabilities.

Usage
Guidelines
Reordering the sequence numbers is useful when you need to insert rules into an existing MAC ACL
and there are not enough sequence numbers available. When all sequence numbers between
rules are exhausted, this feature allows the reassigning of new sequence numbers to entries of an
existing access list.
Example
To reorder the rules in a MAC ACL:
switch#show running-config access-list mac test
!
mac access-list standard test
seq 1 permit 0011.2222.3333
seq 2 permit 0011.2222.4444
seq 3 permit 0011.2222.5555
seq 4 deny 0011.2222.6666
!
switch#resequence access-list mac test 10 10
switch#show running-config access-list mac test
!
mac access-list standard test
seq 10 permit 0011.2222.3333
seq 20 permit 0011.2222.4444
seq 30 permit 0011.2222.5555

values is 4-30.
Defaults
The default is 15 seconds.
Command
Modes
Protocol Spanning Tree mode
Description
Use this command to specify how long the listening and learning states last before the interface
begins the forwarding of all spanning-tree instances. Use the no forward-delay command to return
to the default settings.
Note
STP interface states:
•
•
•
•
Listening - The interface processes the Bridge Protocol Data Units (BPDUs) and awaits possible
new information that might cause it to return to the blocking state.
Learning - The interface does not yet forward frames (packets), instead it learns source
addresses from frames received and adds them to the filtering database (switching database).
Forwarding - An interface receiving and sending data, normal operation. STP still monitors
incoming BPDUs that can indicate it should return to the blocking state to prevent a loop.
Blocking - An interface that can cause a switching loop, no user data is sent or received, but it
might go to the forwarding state if the other links in use fail and the STP determines that the
interface may transition to the forwarding state. BPDU data continues to be received in the
blocking state.
Usage
Guidelines
When you change the spanning-tree forward-delay time, it affects all spanning-tree instances.
When configuring the forward-delay, the following relationship should be kept:
2*(forward-delay - 1)>=max-age>=2*(hello-time + 1)
Examples

Synopsis

spanning-tree edgeport [bpdu-filter | bpdu-guard]

Sets the edge port Bridge Protocol Data Unit (BPDU) filter for the port.
Guards the port against the reception of BPDUs.

Defaults
Edge port is disabled.
Command
Modes
Interface configuration mode
Description
Use this command to enable the edge port feature. This command is only for RSTP and MSTP. Use
the spanning-tree portfast command for STP.
Usage
Note the following details about edge ports and their behavior:
Guidelines
•
•
A port can become an edge port if no BPDU is received.
When an edge port receives a BPDU, it becomes a normal spanning-tree port and is no longer
an edge port.
•
Because ports directly connected to end stations cannot create bridging loops in the network,
edge ports directly transition to the forwarding state, and skip the listening and learning states
Examples
To enable a port to quickly transition to the forwarding state:
switch(conf-if-te-0/1)#spanning-tree edgeport
To set the edgeport BPDU filter for the port:
switch(conf-if-te-0/1)#spanning-tree edgeport bpdu-filter
To guard the port against reception of BPDUs:
switch(conf-if-te-0/1)#spanning-tree edgeport bpdu-guard

Synopsis

Defaults
none
Guard root is disabled.
Interface configuration mode
Command
Modes
Description
Use this command to enable the guard root on the interface. Use the no spanning-tree guard root
command to disable guard root on the selected interface.
Usage
The root port provides the best path from the switch to the root switch.
Guidelines
Note
Guard root protects the root bridge from malicious attacks and unintentional misconfigurations
where a bridge device that is not intended to be the root bridge becomes the root bridge. This
causes severe bottlenecks in the datapath. Guard root ensures that the port on which it is enabled
is a designated port. If the guard root enabled port receives a superior Bridge Protocol Data Unit
(BPDU), it goes to a discarding state.
Examples

name
Specifies a unique name across all of the CEE maps defined within the
system. If the specified CEE map does not exist, then it is created. If the
specified CEE map already exists, then it is updated and the new mapping
automatically propagates to all interfaces bound to the CEE map.
precedence number
Sets the precedence value for controlling the global scheduler policy when
there is conflict between multiple CEE maps and non-CEE QoS configurations.
The range of valid values is 1-100.
Defaults
The default CEE map precedence value is 1.
Global configuration mode
Command
Modes
Description
Use this command create a CEE Map, and then enter the CEE-Map CLI configuration submode for
defining the CEE Provisioning Priority Group Table and Priority-to-Priority Group Table.
The CEE Map model allows different CEE Provisioning on different interfaces. There is only a single
scheduler policy supported across the entire system. For the system to behave to your
expectations, all CEE Map and any non-CEE configuration must specify identical scheduler policies,
such as the number of Strict Priority queues and Deficit Weighted Round Robin (DWRR) weights. In
deployment scenarios where different CEE Map or non-CEE configurations specify conflicting
scheduler policies, then the precedence number parameter can be used to select the CEE Map
controlling the setting of the global scheduler policy. The global scheduler policy is based on the
CEE Map with the highest precedence value.
Use the no cee-map name command to delete the specified CEE map. A CEE map can only be
deleted if it is not bound to any interface.
Usage
All CEE maps take precedence over the non-CEE scheduler policy.
Guidelines
Examples
To create a CEE map:
switch(config)#cee-map test
To delete a CEE map:
switch(config)#no cee-map test
If a CEE map is currently applied on an interface, you cannot delete that CEE map:
switch(config)#no cee-map demo
% Error: Map is still activated

priority-group-table
Configures the bandwidth for each Priority Group.
Synopsis
Operands
priority-group-table pgid [weight weight] [pfc]
no priority-group-table pgid
pgid
Specifies the Priority Group ID (PGID) assigned to a priority group. The range
of valid values is 15.0-15.7 for the eight reserved Strict Priority PGIDs.
weight weight
Maps a weight to a Deficit Weighted Round Robin (DWRR) scheduler queue.
This parameter is only valid for the DWRR Priority Group. The sum of all DWRR
Priority Group weight values must equal 100 percent. The range of valid
values is 1-100.
pfc
Enables the Priority-based Flow Control (PFC) for each priority that gets
mapped to the Priority Group.
Defaults
There is no default value for the weight. The PFC is disabled.
CEE map configuration mode
Command
Modes
Description
Use this command to configure the bandwidth for each Priority Group, to associate a weight to a
DWRR scheduler queue, and to enable the PFC.
You can define up to eight additional DWRR Priority Groups with the PGID values in the range of
0-7. Strict Priority Groups take priority in order from the lowest PGID value to the highest PGID
value, for example, a PGID of 15.0 is a higher priority than a PGID of 15.1 and PGID of 15.1 is
higher priority than PGID 15.2.
Use the no priority-group-table pgid command to return the Priority Group to the default values. For
the Strict Priority Group, the PGID is still valid, but the PFC is disabled. For the DWRR Priority Group,
the PGID is no longer valid and is deleted; the PGID can only be deleted when it is not bound to any
Priority-to-Priority Group Table entry.
Usage
Guidelines
A PGID value of 15 is a special value, which allows you to configure priorities with no bandwidth
limit. The priority groups 15.0-5.7 are pre-defined in the switch.
Examples
To define the CEE map and configure the bandwidth with the Priority Group, use the values in

Defaults
The default CEE Priority mapping table matches the IEEE 802.1Q recommendation for systems
supporting eight traffic classes. The 802.1Q maps CoS 0 (best effort) to Strict Priority Traffic Class
1 (PGID 15.6) and CoS 1 to below best effort Traffic Class 0 (PGID 15.7). All other CoS values go
through unchanged, for example CoS 2 maps to Traffic Class 2 (PGID 15.5), up to CoS 7 and Traffic
Class 7 (PGID 15.0).
Command
Modes
CEE Map Configuration mode
Description
Use this command to provision the CEE Priority-to-Priority Group Table. This table maps each of the
eight ingress CoS into a Priority Group. Use the no priority-table command to return the Priority
mapping table to the default values.
Usage
Guidelines
Only a single CoS can be mapped to a PFC-enabled priority queue. The CoS number must be
identical to the priority queue number. If your configuration violates this restriction an error
message displays and the Priority Group Table is set back to the default values.
When the CEE map is applied, and the interface is connected to the CNA, only one strict priority
PGID (PGID 15.0 to PGID 15.7) is allowed.

Interface configuration mode
Command
Modes
Description
Use this command to specify the interface ingress QoS trust mode, which controls user priority
mapping of incoming traffic. The untrusted mode overrides all incoming priority markings with the
Interface Default CoS. The CoS mode sets the user priority based on the incoming CoS value, if the
incoming packet is not priority tagged, then fallback is to the Interface Default CoS value. Use the
no qos trust command to return to the default.
Usage
Guidelines
When a CEE map is applied on an interface, the qos trust command is not allowed. The CEE map
always puts the interface in the CoS trust mode. This command is not applicable for port-channel
interfaces.
Examples
To set the interface QoS to the trust mode:
switch(conf-if-te-0/1)#qos trust cos
To return the interface QoS to the default value or to the untrusted state:
switch(conf-if-te-0/1)#no qos trust
When a CEE map is applied, the switch does not allow the qos trust cos command and displays the
following error:
switch(conf-if-te-0/1)#cee demo
switch(conf-if-te-0/1)#qos trust cos
% Error: QoS is not in non-CEE Provisioning mode

Use this command to display all of the configured flow control information for a specific interface.
Usage
Guidelines
Use this command to display the runtime state retrieved from the dataplane reflecting the
operation of 802.3x pause or Priority Flow Control (PFC) on an interface. The administrative state
for pause generation and reception or processing is presented for the interface (802.3x mode) or
for each CoS (PFC mode). TX_Pause frame generation statistics are always presented for the
interface. The RX_Pause BitTimes is presented for the interface (802.3x mode) or for each CoS
(PFC mode). When PFC is deployed under the CEE Provisioning model, then the command reports
whether the Data Center Bridging eXchange protocol (DCBX) has overridden the user configuration,
for example when the DCBX detects a mis-configuration between CEE peers, it disables PFC
operationally.
