23-8 User Guide for the Avaya P580 and P882 Multiservice Switches, v6.1
Chapter 23
Packets addressed to the CPU, such as pings, are duplicated out of the
mirror port. Tagged packets that are sent into a source port wit h a VLAN ID
to which the source port is not bound, are not transmitted out the mirror
port. VLAN tag information is not propagated to the mirror port.
* Note: To prevent unnecessary traffic flooding on a mir ror port, put the
mirror port on the same VLAN as the source port.
Two port mirroring features are available for the Avaya Multiservice
switches: Fabric mode 1 port mirroring and Fabric mode 2 port mirroring.
The switch must be in Fabric mode 2 to perform Fabric mode 2 port
mirroring.
Fabric mode 1 port mirroring works with 50-series modules. Fabr ic mode 2
port mirroring works with 80-series modules.
* Note: If you use port mirroring, the Frame Tags field on the Switch
Port Configuration Web page for the port must be set to Use
(default).
