Port Mirroring - Nortel 2000 Using Manual

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 on configuring MultiLink Trunking, VLANs, and spanning
tree groups, refer to Chapter 1 for guidelines on configuring spanning tree groups.
For more information about using the MultiLink Trunking feature, see Chapter 3.
See also Appendixes for configuration flowcharts that can help you use this
feature.

Port mirroring

You can designate one of your switch ports to monitor traffic on any two specified
switch ports (port-based) or to monitor traffic to or from any two specified
addresses that the switch has learned (address-based).
The following sections provide sample configurations for both monitoring modes
available with the Port Mirroring feature:
Note: A probe device, such as the Nortel Networks StackProbe
equivalent, must be connected to the designated monitor port to use this
feature (contact your Nortel Networks sales agent for details about the
StackProbe).
