3-16 AR400 Series Router Software Reference

Software Release 2.6.6

C613-03079-00 REV A

To display the mapping of user priority to QOS egress queues, use the

command:

SHOW SWITCH QOS

The Egress Rules

After the Forwarding Process has determined the ports and transmission

queues from which to forward a frame, the Egress Rules for each port

determine whether the outgoing frame is VLAN tagged with its numerical

VLAN Identifier (VID).

When a port is added to a VLAN, it is configured to transmit either untagged

or VLAN tagged packets, using the command:

ADD VLAN={vlan-name|1..4094} PORT={port-list|ALL}

[FRAME={TAGGED|UNTAGGED}]

In the default configuration, no ports transmit VLAN tagged packets.

This setting can be changed for a port that is already part of a VLAN, using the

command:

SET VLAN={vlan-name|1..4094} PORT={port-list|ALL}

FRAME={UNTAGGED|TAGGED}

Triggers

The Trigger Facility can be used to automatically run specified command

scripts when particular triggers are activated. When a trigger is activated by an

event, global parameters and parameters specific to the event are passed to the

script that is run. For a full description of the Trigger Facility, see Chapter 28,

Trigger Facility.

The router can generate triggers to activate scripts when a switch port goes up

or down.

The following section lists the events that may be specified for the Switching

module for the EVENT parameter, the parameters that may be specified as

module-specific-parameters for the Switching module, and the arguments passed

to the script activated by the trigger.

Module Layer 2 Switching module: MODULE=SWI
