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 example,
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
Ports can be statically grouped into an aggregated link,
also known as a “trunk”. This increases the bandwidth
of a network connection and ensures fault recovery.
