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. Refer to the port-monitor vlan-tagging command
below.
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 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
5.16.2 show ports monitor
The show ports monitor user EXEC command displays the port monitoring status.
Syntax
show ports monitor
Default Configuration
This command has no default configuration.
