Figure 17   Uplink VLAN Configuration

To set up the configuration shown in Figure 17, do the 
following:

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.

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.

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.

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.

To remove an existing VLAN:

In the VLAN ID list, select the VLAN ID that you want to 
delete.

Click Remove.

The VLANs page refreshes, and the VLAN ID that you 
deleted disappears from the VLAN ID list.

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.
