Displaying the Current Mirror and Monitor Port Configuration
You can display the current port mirroring and monitoring configuration using the following CLI method.
USING THE CLI
To display the current mirroring and monitoring configuration, enter the following command at any level of the CLI:
BigIron(config)# show monitor
Mirror Interface: ethernet 4/1
Monitored Interfaces:
Both Input Output
---------------------------------------------------
ethernet 4/3
Syntax: show monitor
This example shows the monitoring and mirroring configuration set up by the commands in the example in the
previous section. Port 4/1 is the mirror interface, to which the software copies (“mirrors”) the traffic on port 4/3. In
this case, both directions of traffic on the monitored port are mirrored to port 4/1.
If only the incoming traffic is mirrored, the monitored interface is listed under Input. If only the outbound traffic is
mirrored, the monitored interface is listed under Output.
USING THE WEB MANAGEMENT INTERFACE
You cannot display this information using the Web management interface.
