Figure 17 Uplink VLAN Configuration
To set up the configuration shown in Figure 17 , do
the following:
1
Create VLAN2 on both Switch 1 and Switch 2, and
assign the same name to it. You need not create
VLAN1 since it exists by default.
2
On Switch 1, set the ports that you want to be part of
VLAN2 to
D (desktop egress packet). Set one port (for
example, port 16) to U (uplink egress packet).
Click Apply .
3
On Switch 2, set the ports that you want to be part of
VLAN2 to
D (desktop egress packet). Set one port (for
example, port 8) to U (uplink egress packet).
Click Apply .
4
Connect the uplink port on Switch 1 (in this example,
port 16) to the uplink port on Switch 2 (in this exam-
ple, port 8).
Those ports on Switch 1 that are members of VLAN2
can now communicate with those ports on Switch 2
that are members of VLAN2.
Removing a VLAN
To remove an existing VLAN:
1
In the VLAN ID list, select the VLAN ID that you want
to delete.
2
Click Remove .
The VLANs page refreshes, and the VLAN ID that you
deleted disappears from the VLAN ID list.
Configuring Link Aggregation
Link aggregation, also called “port trunking”, refers
to bonding multiple ports into a single group to effec-
tively combine the bandwidth into a single connec-
tion or a “trunk”. If you are connecting the Switch to
another switch or to an Internet backbone, you can
aggregate links on the Switch to increase throughput
and prevent packet loopback between switches.
For link aggregation to work, the trunks must be con-
figured on both ends (switches).
