Monitoring and Analyzing Switch Operation

Traffic Mirroring

Configure the Mirroring Destination on a Remote Switch (Page B-50):IP Address and UDP Port on Source SwitchIP Address and Exit Port on Remote Switch

mirror endpoint ip < src-ip-addr > < src-udp-port > < dst-ip-addr > port < exit-port >

Enter this command on a remote switch to configure the exit port to use in a remote mirroring session. You will configure the mirroring source on the local switch in the next step.

The mirror endpoint ip command configures:

D e p r e c a t e d C o m m a n d

■The unique UDP port number to be used for the mirroring session on the source switch. The recommended port range is from 7933 to 65535.

■The IP address of the source switch to use in the session■The IP address and exit-port number on the remote (endpoint) switch

In a remote mirroring endpoint, the IP address of exit port and the remote destination switch can belong to different VLANs.

Configure the Mirroring Source on the Local Switch (Page B-52)

mirror < 1 - 4 > [name < name-str>] remote ip < src-ip> < src-udp-port> < dst-ip>

The no mirror <1 - 4> command form removes both the mirroring session and any mirroring source(s) previously assigned to the session by the following commands.

Configure Traffic-Direction Criteria to Select Traffic (Page B-57)

[no] < interface < port/trunk/mesh > vlan < vid-#>>

monitor all < in out both > mirror < 1 - 4 name-str> [< 1 - 4 name-str> ... ]

Configure ACL Criteria to Select Inbound Traffic (Page B-62)

[no] < interface < port/trunk/mesh > vlan < vid-#>> monitor ip access-group < acl-name> in

mirror < 1 - 4 name-str> [< 1 - 4 name-str> ... ]
