Additional tips about the MultiLink Trunking feature
When you create a MultiLink Trunk, the individual trunk members (the specific
ports that make up the trunk) logically connect and react as a single entity. For
example, if you change spanning tree parameters for any trunk member, the
spanning tree parameters for all trunk members change.
All configured trunks are indicated in the Spanning Tree Configuration screen.
The Trunk field lists the active trunks, adjacent to the port numbers that
correspond to the specific trunk member for that trunk.
When a trunk is active, you can disable spanning tree participation using the
Trunk Configuration screen or using the Spanning Tree Configuration screen.
When a trunk is not active, the spanning tree participation setting in the Trunk
Configuration screen does not take effect until you set the Trunk Status field to
Enabled.
The trunk is also viewed by management stations as a single spanning tree port.
The spanning tree port is represented by the trunk member with the lowest port
number. For example, if ports 13, 14, 15, and 16 are trunk members of trunk T1,
the management station views trunk T1 as spanning tree port 13.
For more information about using the MultiLink Trunking feature, see “MultiLink
Trunk Configuration Menu screen” on page 133 .
See also Appendix C, “Quick configuration for MultiLink Trunking,” on page 193
for a configuration flowchart that can help you use this feature.
Port mirroring
You can designate one of your switch ports to monitor ingress traffic on a single
specified switch port (port-based).
Note: A probe device, such as Nortel Networks StackProbe, must be
connected to the designated monitor port to use this feature (contact your
Nortel Networks sales agent for details about the StackProbe).
