Ports cannot be configured as a group using the interface range ethernet command.
Note:
The Port Mirroring target must be a member of the Ingress VLAN of all Mirroring source ports. Therefore,
multicast and broadcast frames in these VLANs are seen more than once. (Actually N, where N is the
number of mirroring source ports).
When both transmit (Tx) and receive (Rx) directions of more than one port are monitored, the capacity
may exceed the bandwidth of the target port. In this case, the division of the monitored packets may not
be equal. The user is advised to use caution in assigning port monitoring.
Example
The following example shows how traffic on port e8 (source port) is copied to port g1 (destination port).
Console(config)# interface ethernet g1
Console(config-if)# port monitor e8
