18 Switching Enhancements Release Note

Software Version 2.9.1

C613-10486-00 REV C

Switching Enhancements

This Software Version includes the following enhancements to Switching:

■ Multiple Uplink Ports in Private VLANs

■ Group Parameter Required for Private VLAN Ports

This section describes the enhancements. The modified commands to

implement them are described in Command Reference Updates.

Multiple Uplink Ports in Private VLANs

This enhancement makes it possible to add multiple uplink ports to a private

VLAN on Rapier i, AT-8600, AT-8700XL, and AT-8800 Series switches. This

enables you to use private VLANs in a ring or meshed topology.

To add the uplink ports, specify the list of ports in the existing command:

add vlan={vlan-name|1..4094} port=port-list

[frame={untagged|tagged}] uplink

For Rapier 48i and AT-8748XL switches, note that all ports in the private VLAN

must be in the same switch instance. See the Switching chapter of the Software

Reference for more information.

Command Changes

This enhancement does not affect any commands.

Group Parameter Required for Private VLAN Ports

With Software Version 2.9.1, when you add a trunk group to a private vlan as

private ports, you must specify the group parameter.

The add switch trunk and create switch trunk commands now check that all

ports belong to the same group if they belong to the same private VLAN.

Command Changes

The following table summarises the modified command:
