Monitoring and Analyzing Switch Operation
Traffic Mirroring
N o t e s
B-52
If a mirroring session is configured with a mirroring source that uses an ACL
for traffic selection, then no other mirroring sources can be configured to use
that session. Conversely, if a mirroring session is already configured with a
mirroring source that does not use an ACL, then the session cannot accept an
additional mirroring source that does use an ACL.
The ACL option applies only to IP traffic entering the switch on the specified
interface. An ACL used for mirroring purposes ignores non-IP traffic when
selecting traffic to mirror.
The switch ignores any log statements included in deny ACEs in an ACL used
for mirroring purposes.
ACL (Access Control List) Selection Criteria for Mirroring from a
Port, Trunk, or Mesh Interface. ACL traffic filtering for mirroring pur-
poses operates as described in the ACL chapter except that the effect of the
ACL is to mirror or not mirror IP traffic, instead of to permit or deny the IP
traffic.
Syntax: [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 >]
This command assigns a mirroring source to a previously
configured mirroring session on a source switch. It specifies the
port. trunk, and/or mesh source(s) to use, the (previously
configured) ACL to use for selecting traffic to mirror, and the
session identifier. Use this option to mirror selected IP traffic
entering the switch on specified ports, trunks, and/or a mesh.
The no form of the command removes the mirroring source
assigned to the session, but does not remove the session itself.
This enables you to repurpose a a session by removing an
unwanted mirroring source and adding another in its place.
interface < port/trunk/mesh >: Identifies the port(s), static
trunk(s), and/or mesh on which to mirror traffic permitted
by the ACL. Use a hyphen for a range of consecutive ports
or trunks ( a5-a8, Trk2-Trk4 ). Use a comma to separate
non-contiguous interfaces ( b11,b14,Trk4,Trk7 ).
