For example, to assign port 6 as the monitoring port:
switch(config)# mirror-port 6
To turn off monitoring:
switch(config)# no mirror-port
Selecting or removing monitoring source interfaces
After you configure a monitor port you can use either the global configuration level or the interface context level to
select ports or static trunks as monitoring sources. You can also use either level to remove monitoring sources.
Syntax:
[no] interface <monitor-list> monitor
<monitor-list>
Includes port numbers and static trunk names such as 4, 7, 5-8, trk1
Identifies the switch elements to monitor through the currently configured monitor port. You can monitor the ports
and static trunks available on the switch.
Elements in the monitor list can include port numbers and static trunk names at the same time.
For example, with a port such as port 6 configured as the monitoring (mirror) port, you would use either of the
following commands to select these interfaces for monitoring:
• 1–3, and 5
• Trunk 2
Selecting ports and static trunks as monitoring sources
switch(config)# int 1-3, 5, trk2, monitor
Disabling monitoring at the interface context and the global config level
switch(eth-1-3, 5)# no int 5 monitor
switch(eth-1-3, 5)# no monitor
switch(config)# no int 5 monitor
switch(config)# no int 1-3, 5 monitor
• These two commands show how to disable monitoring at the interface context level for a single port or all ports
in an interface context level.
• These two commands show how to disable monitoring at the global config level for a single port or a group of
ports.
