Creating a Mirroring Session and Enabling Mirroring Status

To create a mirroring session with protection against blocking and mirroring status enabled (turning port
mirroring on), enter the
session ID number, the source and destination slot/ports, optional unblocked VLAN ID number and
enable, as shown in the following example:
-> port mirroring 6 source 2/3 destination 2/4 unblocked 750 enable
This command line specifies mirroring session 6, with the mirrored (active) port located in slot 2/port 3,
and the mirroring port located in slot 2/port 4. The mirroring port on VLAN 750 is protected from Span-
ning Tree updates, and Mirroring Status is enabled (i.e., port mirroring is turned ON). Note that the port
mirroring session identifier and slot/port locations of the designated interfaces must always be specified.
Note. Port mirroring session parameters cannot be modified when a mirroring session is enabled. Before
you can modify parameters, the mirroring session must be disabled.

Disabling a Mirroring Session (Disabling Mirroring Status)

To disable the mirroring status of the configured session between a mirrored port and a mirroring port
(turning port mirroring off), use the
the port mirroring session ID number and the keyword disable.
In this example the command specifies port mirroring session 6, with the mirrored (active) port located in
slot 2/port 3, and the mirroring port located in slot 6/port 4. The mirroring status is disabled (i.e., port
mirroring is turned off):
-> port mirroring 6 source disable
Note. You can modify the parameters of a port mirroring session that has been disabled.
Keep in mind that the port mirroring session configuration remains valid, even though port mirroring has
been turned off. Note that the port mirroring session identifier and slot/port locations of the designated
interfaces must always be specified.
Note. Note that the port mirroring session identifier and slot/port locations of the designated interfaces
must always be specified.

Configuring Port Mirroring Direction

By default, port mirroring sessions are bidirectional. To configure the direction of a port mirroring session
between a mirrored port and a mirroring port use the
by entering port mirroring followed by the port mirroring session ID number, the source and destination
slot/ports, and bidirectional, inport, or outport.
Note. Optionally, you can also specify the optional unblocked VLAN ID number and either enable or
disable on the same command line.
