• The destination port is set by specifying an Ethernet interface.
• The mirror port and monitor port speeds should match, otherwise traffic
may be dropped from the monitor port.
• You can create multiple mirror sessions, but all sessions must share the
same destination port. However, you should avoid sending too much
traffic to the destination port from multiple source ports.
Example
The following example configures the switch to mirror all packets from port
6 to 11:
Console(config)#interface ethernet 1/11
Console(config-if)#port monitor ethernet 1/6 both
Console(config-if)#
show port monitor
This command displays mirror information.
