Monitoring and Analyzing Switch Operation
Traffic Mirroring
(On the destination switch, the mirrored traffic entry port for a given session
and the exit port for that session must belong to the same VLAN.)
To Configure or Remove a Mirroring Session on a Source Switch
Defines a Remote Mirroring Session on a Source Switch (Page B-43):
mirror < 1 - 4 > [name < name-str >] remote ip < src-ip > < src-udp-port > < dst-ip >
no mirror < 1 - 4 >
The no command form removes both the mirroring session and any mirroring
source(s) previously assigned to the session by the following commands.
To Configure Port or Trunk Mirroring on a Source Switch:
Directional Criteria Selects Traffic To Mirror (PagesB-48):
[no] interface < port/trunk/mesh > monitor all < in | out | both > mirror
< 1 - 4 | name-str > [< 1 - 4 | name-str > < 1 - 4 | name-str > < 1 - 4 | name-str >]
Inbound ACL Criteria Selects Traffic To Mirror (PagesB-52):
[no] interface < port/trunk/mesh > monitor ip access-group < acl-name > in mirror
< 1 - 4 | name-str > [< 1 - 4 | name-str > < 1 - 4 | name-str > < 1 - 4 | name-str >]
The < name-str > option applies only if the specified mirroring session has
already been configured with the name < name-str > option in the mirror
command.
The no command form removes the < port/trunk/mesh > mirroring source from
the specified session, but leaves the session available for other assignments.
To Configure VLAN Mirroring on a Source Switch:
Directional Criteria Selects Traffic To Mirror (PagesB-50):
[no] vlan < vid-# > monitor all < in | out | both > mirror < 1 - 4 | name-str >
[< 1 - 4 | name-str > < 1 - 4 | name-str > < 1 - 4 | name-str >]
Inbound ACL Criteria Selects Traffic To Mirror (PagesB-54:
[no] vlan < vid-# > monitor ip access-group < acl-name > in mirror < 1 - 4 | name-str >
[< 1 - 4 | name-str > < 1 - 4 | name-str > < 1 - 4 | name-str >]
The < name-str > option applies only if the specified mirroring session has
already been configured with the name < name-str > option in the mirror
command.
The no command form removes vlan < vid-# > mirroring source from the
specified session, but leaves the session available for other assignments.
