Monitoring and Analyzing Switch Operation

 

Traffic Mirroring

 

 

Caution

When configuring a remote mirroring session, always configure the destina­

 

tion switch first. Configuring the source switch first can result in a large

 

volume of mirrored, IPv4-encapsulated traffic arriving at the destination

 

without an exit path, which can slow switch performance.

 

Syntax: mirror endpoint ip < src-ip > < src-udp-port > < dst-ip > < exit-port-# >

 

 

no mirror endpoint ip < src-ip> < src-udp-port> < dst-ip>

 

This command is used on a destination switch to configure

 

the remote endpoint of a mirroring session. The command

 

uniquely associates the mirrored traffic from the desired

 

session on a monitored source with a remote exit port on the

 

destination switch. You must use the same set of source and

 

destination parameters you when configure the same session

 

on both the source and destination switches.

 

For a given mirroring session, the same <src-ip >, < src-udp­

 

port >, and < dst-ip > values must be entered with the mirror

 

endpoint ip command on the destination switch, and later with

 

the mirror remote ip command on the source switch. Refer to

 

the mirror remote ip command syntax on page B-53 for more

 

information.

 

The no form of the command deletes the mirroring endpoint

 

for the configured session on the remote destination switch.

 

Caution: Do not remove the configuration of a remote

 

mirroring endpoint support for a given session if there are

 

source switches currently configured to mirror traffic to the

 

endpoint.

 

< src-ip >: This parameter must exactly match the < src-ip >

 

address you configure on the source switch for the remote

 

session.
