Show Ports Monitor - Dell PowerConnect 3524 Cli Reference Manual

• The following restrictions apply to ports configured to be destination ports:
• The port cannot be already configured as a source port.
• The port cannot be a member in a port-channel.
• An IP interface is not configured on the port.
• GVRP is not enabled on the port.
• The port is not a member in any VLAN, except for the default VLAN (will automatically be
removed from the default VLAN).
• The following restrictions apply to ports configured to be source ports:
• Port monitoring Source Ports must be simple ports, and not port-channels.
• The port cannot be already configured as a destination port.
• All the frames are transmitted as either always tagged or always untagged.
General Restrictions:
• 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 equals four).
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 copies traffic on port 1/e8 (source port) to port 1/e1 (destination port).
Console(config)# interface ethernet 1/e1
Console(config-if)# port monitor 1/e8
