Packets addressed to the CPU, such as pings, are duplicated out of the
mirror port. Tagged packets that are sent into a source port with 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 mirror 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. Fabric 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).
