Mirror Port Configuration
Port mirroring is the duplication of traffic from a set of source ports onto a destination port. A mirror
session associates a set of source ports to a destination port.
? The monitor session source command configures an Ethernet or port channel interface as the
source port of a specified port mirroring session.
? The monitor session destination command configures an Ethernet interface as the destination port
of a specified port mirroring session.
Example
? These commands configure Ethernet interface 8 as the source port and Ethernet interface 7 as
the destination port for the redirect_1 mirroring session. The session mirrors the source port’s
ingress and egress traffic.
switch(config)#monitor session redirect_1 source ethernet 7
switch(config)#monitor session redirect_1 destination ethernet 8
?
This command displays the configuration of the redirect_1 mirroring session.
switch(config)#show monitor session
