Port-based mirroring configuration
Figure 2 "Port-based mirroring configuration example" (page 18) shows an
example of a port-based mirroring configuration where port 23 is designated
as the monitor port for ports 24 and 25 of Switch S1. Although this example
shows ports 24 and 25 monitored by the monitor port (port 23), any of the
trunk members of T1 and T2 can also be monitored.
In this example, port X and port Y are members of Trunk T1 and Trunk
T2. Port X and port Y are not required to always be members of Trunk
T1 and Trunk T2.
Note: Trunks cannot be monitored and trunk members cannot be
configured as monitor ports (see Nortel Ethernet Switch 460/470
Configuration — VLANs, Spanning Tree, and Multilink Trunking
(NN47210-505) for details).
Figure 2 "Port-based mirroring configuration example" (page 18) shows the
Port Mirroring Configuration screen setup for this example.
