Configuring Inter-Switch Links
An inter-switch link (ISL) is a port that connects VLANs from two different
switches; it’s the means to share VLAN information between switches on a
network.
To configure a port as an ISL, you must do the following:
G Add the ISL port to each VLAN that is shared by the two switches.
This configures the port to share the VLAN traffic between the
two switches.
G For each VLAN, remove the ISL port from the VLAN’s set of
untagged ports. By default, when you add a port to a VLAN, it will
send tagged and untagged frames. This step configures the port to
only send tagged frames.
G In most cases, configure the ISL port to receive tagged frames. A
port that is configured to receive only tagged frames will drop
untagged frames.
Once the port is configured as an ISL it will pass frames from switch to
switch, but it can acts as a gate that only passes frames associated with
specific VLANs.
Adding an ISL Port to VLANs
You add a port to a VLAN in the VLAN Static Group Configuration Menu.
1 Type v in the Configuration Menu to access the VLAN
Management Menu, then type s to access the VLAN
Group Static Configuration Menu.
2 Use the commands on the bottom of the menu to select
the VLAN you want.
