Port trunking is the ability to group several ports to increase the
bandwidth between this switch and another compatible switch. This
is an inexpensive way to increase bandwidth. We define port
trunking as the ability to group set of ports (up to 4 groups).

Spanning Tree Protocol Configuration
Spanning tree is a link management protocol that provides path
redundancy while preventing undesirable loops in the network. For
Layer 2 Ethernet network to function properly, only one active path
must exist between two stations.
The spanning-tree algorithm calculates the best loop-free path
throughout a switched network. STP forces redundant data paths
into a standby (blocked) state. If a network segment in the spanning
tree fails and a redundant path exists, the spanning-tree algorithm
recalculates the spanning tree topology and activates the standby
path.

Multicasting is used to support real-time applications such as video
conferencing or streaming audio. IGMP (Internet Group Multicast
Protocol) allows you to query for any attached hosts who want to
receive a specific multicast service. The switch looks up the IP
Multicast Group used for this service and adds any port, which
received a similar request to that group. It then propagates the
service request on to any neighboring multicast switch to ensure
that it will continue to receive the multicast service.
By supporting IGMP (Internet Group Management Protocol)
Snooping, the switch can forward multicast traffic intelligently.
Packets are forwarded to the ports that belong to the multicast
group instead of being
broadcast to all ports and possibly disrupting network performance.
This lookup table reflects the multicast group(s) (up to 32)
configuration of your system and provides an overview of the
port(s) map to each multicast group.

45, Intelligent ) is used.

The Switch provides versatile configuration options for the network.
It is ideally suited as a workgroup or segment Switch in a network; it
has the flexibility to provide Switched 10Mbps to the desktop or
shared hubs, aggregate traffic from workgroup Switches, or provide
dedicated 100Mbps or 1000Mbps ( Gigabit ) to servers with
bandwidth-intensive applications. And because all Fast Ethernet
ports auto-negotiate for operation at 100 Mbps the Switch is
perfectly suited to an evolving network environment where demand
for network speed is increasing.
Collapsed Backbone Application
For small network where rapid growth can be expected in the near
future, this Switch is an ideal solution supporting backbone
connectivity.
The Switch can be used as a standalone Switch for a group of
heavy traffic users. Switching is brought to the desktop either
through a single end-station per Switch port or through a multi-port
Switch.
A 1000 Mbps server is connected to the Switch, providing end
stations high-speed accessibility to its applications. This
configuration provides dedicated 100 Mbps connections to the
network center, to the server, and up to 40 users ( while 2 Optional
8-port module are installed ).
When the network needs expansion, you can simply connect the
Switch to any IEEE 802.3 ( Ethernet ), IEEE 802.3u ( Fast Ethernet
) and 802.3ab ( Gigabit Ethernet ) compliant Switch utilizing the
Auto MDI/MDIX function. This Switch can also cooperate with a
wide range of networking devices (e.g., firewall routers and printer
servers) added to the network.

Figure 5-1. Collapsed Backbone Application
Departmental Bridge
For enterprise networks where large data broadcasts are constantly
processed, this Switch is an ideal solution for department users to
connect to the corporate backbone. The LevelOne GSW-2490TXM
SNMP Switch used as segment Switch can alleviate user
contention for bandwidth and eliminate server and network
bottlenecks. All ports can connect to high-speed department servers
that need high bandwidth. This Switch provides parallel
communications within it’s Gigabit port, which can run up to 2000
Mbps at Full-duplex.
The Switch makes key servers available to more users by allowing
multiple conversations to occur concurrently, thereby significantly
expanding overall network throughput. Moreover, this Switch eases
supervision and maintenance by allowing network manager
centralize multiple servers in a single location.

Figure 5-2: Departmental Bridge Application
NOTE: Full-duplex operation only applies to point-to-point access
(for example, when attaching the Switch to a workstation, server, or
another Switch). When connecting to hubs, use a standard
cascaded connection set for half-duplex operation.
High Performance Switched Workgroup
This Switch is also a good solution for connecting two workgroups,
supporting the throughput, for example, of 800Mbps. This
application is useful for power groups that need high bandwidth.
The most common LAN implementations use a combination of
standard switches, bridges and routers. The bridges and routers
quickly become bottlenecks, reducing overall network throughput.
Switching to higher-speed LANs such as FDDI or ATM is not a good
choice for most people.
However, such broadband equipment is still extremely expensive
and hard to maintain. Besides, you have to replace all existing
Ethernet cable and adapter cards, restructure your network, and
53
Download from Www.Somanuals.com. All Manuals Search And Download.
implement more expensive administration procedures.
The Switch can provide the same bandwidth of FDDI and ATM at
much lower costs. In addition, all current adapters and network
devices can still be used. The Switching cross-domain connection is
better than bridge and router because users can retain LAN
structure in which any node can freely communicate with any other
node.
Figure 5-3: High Performance Switched Workgroup Application
IEEE 802.1Q VLAN Application
The Switch supports up to 128 Group, IEEE 802.1Q-compatible
virtual LAN ( VLANs ).
Port-based VLAN Workgroup
You can group the Switch ports into broadcast domains by
assigning them to the same VLAN to increase network capacity and
performance. With network segmentation, each Switch port
connects to a segment that is a single broadcast domain. Packets
received in one VLAN can only be forwarded within that VLAN.
VLAN allows the grouping of end stations logically, based not on
physical location but on business policies such as job function or
department. Members of a group can be dispersed throughout a
facility - they do not have to be connected in close physical
locations.
Hence, group members can coordinate their data communication
requirements regardless of the actual working locations; and the
logical network can extend to any point you want it to. Moreover,
54

VLAN groups can be modified at any time to add, move or change
users without any re-cabling.
Figure 5-4: VLAN Workgroup Application
Shared Server
The Switch compliant to the IEEE802.1Q tagging VLAN standard
allows ports to exist in multiple VLANs for shared resources, such
as servers, printers, and Switch-to-Switch connections. It is also
possible to have resources exist in multiple VLANs on one Switch
as shown in the following figure.
Figure 5-5: Shared Server
In this example, stations on different VLANs share resources. As a
result, VLAN 1 and VLAN 2 can access VLAN 3 for printing. The
broadcasts from ports configured in VLAN3 can be seen by all
