Ingress Vlan Security; Icc-Vlan; Vlan Cli Commands - Avaya G250 Administration

When the VLAN table reaches its maximum capacity, you can not configure any more VLANs. If
this occurs, use the clear vlan command, followed by the name or number of the VLAN you
want to delete, to free space in the VLAN table. Any new VLANs configured by you are made
known to all the modules in the system.

Ingress VLAN security

Ingress VLAN Security enables easy implementation of security, and is always active. A port
that is assigned to a VLAN allows packets tagged for that VLAN only to enter the through that
port. Unassigned packets receive the PVID of the port and are therefore allowed to enter.

ICC-VLAN

When the G250/G350 includes an ICC, the ICC connects to the G250/G350 via an internal
switch. By default, the ICC is connected on Vlan 1. The VLAN to which the ICC connects is
called the ICC-VLAN.
You can use the icc-vlan command to attach the ICC to a different VLAN. Enter the context
of the VLAN interface to which you want to attach the ICC switch, and type the icc-vlan
command.
To show the current ICC-VLAN, type the show icc-vlan command from the general context.
The following example sets Vlan 2 as the ICC-VLAN:
G350-001(super)# interface vlan 2
G350-001(super-if:Vlan 2)# icc-vlan
Done!
G350-001(super-if:Vlan 2)# exit
G350-001(super)# show icc-vlan
VLAN 2
G350-001(super)#

VLAN CLI commands

The following commands are used to configure VLANs. For more information about these
commands, see Avaya G250 and Avaya G350 CLI Reference, 03-300437.
Use the clear port static-vlan command to delete VLANs statically configured on
●
a port.
Use the clear vlan command to delete an existing VLAN and its interface, remove the
●
entry from the VLAN table, and return ports from this VLAN to the default VLAN #1. When
you clear a VLAN, all ports assigned to that VLAN are assigned to the default VLAN #1.
