- If you attempt to set up port mirroring on a port that is administratively disabled, and you configure the disabled port as a source or mirror port, note the following:
Traffic sent to a disabled source port will be lost. A disabled port set up as a mirror port will not be able to send any traffic to a monitoring device.
Avaya recommends that you check any ports to be used in port mirroring to ensure that the ports are active.
- When using Fabric mode 2 port mirroring, you cannot mirror transmit traffic of multiple source ports to one mirror port.
- When you use Fabric mode 2 port mirroring, both the source port and mirror port must either:
- Be on the same VLAN and have the same VLAN binding
OR
- Have VLAN binding set to bind to all
- Avaya recommends that you do not set up a port mirror with a source port or mirror port that is bandwidth limited. This is because packets are dropped during the bandwidth limiting process. Since both source and mirror packets are subject to drop, and because packets are dropped at random, if packets are dropped from either the source or the mirror traffic (or both), there is no guarantee that the mirror traffic will match the source traffic.
- Fabric mode 2 port mirroring is not supported for hunt group ports.
