Traffic Mirroring

ACL (Access Control List) Selection Criteria for Mirroring from a
VLAN Interface.
Syntax: 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 >]
This command assigns a mirroring source to a previously
configured mirroring session on a source switch. It specifies the
VLAN source to use, the (previously configured) ACL to use for
selecting traffic to mirror, and the session identifier. Use this
option when you want to mirror selected IP traffic entering the
switch on a specific VLAN.
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.
vlan < vid-# >: Identifies the VLAN on which to mirror traffic.
monitor ip access-group < acl-name > in: For the interface
specified by < vid-#>, selects the IP traffic to mirror based on
the selection criteria specified in the named ACL. (The ACL
must be already be configured on the switch. Refer to "ACL
Operation for Mirroring Applications" on page B-51.)
(Using monitor without mirroring criteria or session
number affects session 1. Refer to "Monitor Command" on
page B-71.)
< acl-name >: For traffic entering the switch on the
specified interface, mirror the IP traffic having a
match with the permit ACEs in the named ACL. (IP
traffic matching a deny ACE, including the implicit
deny any or deny any any in the named ACL is dropped.)
mirror < 1 - 4 | < name-str >: Assigns the traffic defined by the
interface to a session by number or (if configured) by name.
(The session must have been previously configured. Refer
to "3. Configure the Mirroring Session on the Source
Switch" on page B-43.) Depending on how many sessions
are already configured, you can use the same command to
assign the specified source to up to four numeric or
alphanumeric identifiers. For example, 1 2 test-
mirror. For limits on configuring mirroring sources to a
given session, see "Mirroring Source Limits" on page B-47.
< 1 - 4 > : Assigns a numeric session identifier to
associate with the traffic selected for mirroring.
