monitor mac mac-addr
Configures the MAC address as selection criteria for mirroring traffic on any port or learned VLAN on the switch.
{src | dest | both}
Specifies how the MAC address is used to filter and mirror packets in inbound
and/or outbound traffic on the interfaces on which the mirroring session is
applied:
• src: Mirrors all packets in inbound traffic that contain the specified MAC
address as source address.
• dest: Mirrors all packets in outbound traffic that contain the specified MAC
address as destination address.
NOTE: The MAC address of the switch is not supported as either
the source or destination MAC address used to select mirrored
traffic.
both: Mirrors all packets in both inbound and outbound traffic that contain the
specified MAC address as either source or destination address.
mirror [1 - 4 | name-
str]
Assigns the inbound and/or outbound traffic filtered by the specified MAC
address to a previously configured mirroring session. The session is identified
by a number or (if configured) a name.
Depending on how many sessions are configured on the switch, you can use
the same command to configure a MAC address as mirroring criteria in up to
four sessions. To identify a session, you can enter either its name or number; for
example: mirror 1 2 3 traffsrc4
1 - 4: Specifies a mirroring session by number, for which the configured MAC
address is used to select and mirror inbound and/or outbound traffic.
Packets that are sent or received on an interface configured with a mirroring session and that contain the MAC
address as source and/or destination address are mirrored to a previously configured destination device.
To remove a MAC address as selection criteria in a mirroring session, you must enter the complete Command
syntax, for example, no monitor mac 998877-665544 dest mirror 4.
The no form of the command removes the MAC address as a mirroring criteria from an active session, but does
not remove the session itself. This enables you to repurpose a session by removing an unwanted mirroring
criteria and adding another in its place.

Context: Global configuration
Syntax
