these commands. 

To set up port mirroring, use the following CLI command: 

(configure)# 

port-range> mirror-port <mod-port-spec> channel <channel> direction 
{tx | rx | both | sa | da} sampling {always | disable | periodic} [sa <MAC-
address>] [da <MAC-address>] [max-packets-sec <max-packets-sec-
value>] 

Direction/Filter

The direction of traffic that you want to mirror and the 
filter that you want to set up, if any. Options are: 

• Receive/None-Mirrors all receive traffic. 

• Transmit/None-Mirrors all transmit traffic. 

• Both/None-Mirrors all transmit and receive 

traffic. 

• Receive/SA Filter-Mirrors receive traffic that 

has the source MAC address that you specify in 
the Source MAC (SA) field. 

• Transmit/DA Filter-Mirrors transmit traffic that 

has the destination MAC address that you 
specify in the Destination MAC (DA) field. 

Sampler Type

Specifies how often you want the mirror port to

• Disable

• Always

• Periodic

Max Packets per

The maximum number of packets per second that you 
want the mirror port to receive. 

Enter a number in this field only if you selected 
Periodic in the Sampler Type field. 

Channel Filter

Displays the channel number.

Source MAC (SA)

The source MAC address that you want to mirror 
traffic for. 

Enter a MAC address in this field only if you selected 
Receive/SA Filter in the Direction/Filter field. 

Destination MAC 
(DA)

The destination MAC address that you want to mirror
