IEEE 802.1Q VLANs

BayStack 410-24T switches support up to 64 port-based VLANs with IEEE

802.1Q tagging available per port.

When a switch port is configured to be a member of a VLAN, it is added to a

group of ports (workgroup) that belong to one broadcast domain. You can assign

different ports (and therefore the devices attached to these ports) to different

broadcast domains.

This feature allows network flexibility because you can reassign VLANs to

accommodate network moves, additions, and changes, eliminating the need to

change physical cabling.

For more information about 802.1Q VLANs, see “

IEEE 802.1Q VLAN

Workgroups” on page 1-36.

Port Mirroring

The port mirroring feature (sometimes referred to as conversation steering) allows

a user to designate a single switch port as a traffic monitor for up to two specified

ports or two media access control (MAC) addresses.

You can specify Port-Based monitoring, where all traffic on specified ports is

monitored, or Address-Based monitoring, where traffic between specified MAC

addresses is monitored.

You can attach a probe device (such as a Nortel Networks StackProbe, or

equivalent) to the designated monitor port.

For more information about the port mirroring feature, see “P

ort Mirroring

(Conversation Steering)” on page 1-80.
