Configuring port mirroring and monitoring
20
The both, in, and out parameters specify the traffic direction you want to monitor on the mirror port.
There is no default.
To display the port monitoring configuration, enter the show monitor and show mirror commands.
Monitoring an individual trunk port
You can monitor the traffic on an individual port of a static trunk group, and on an individual port of
an LACP trunk group.
By default, when you monitor the primary port in a trunk group, aggregated traffic for all the ports in
the trunk group is copied to the mirror port. You can configure the device to monitor individual ports
in a trunk group. You can monitor the primary port or a secondary port individually.
To configure port monitoring on an individual port in a trunk group, enter commands such as the
following.
PowerConnect(config)#mirror-port ethernet 2/6
PowerConnect(config)#trunk e 2/2 to 2/5
PowerConnect(config-trunk-2/2-2/5)#config-trunk-ind
PowerConnect(config-trunk-2/2-2/5)#monitor ethernet 2/4 ethernet 2/6 in
Traffic on trunk port e 2/4 will be monitored, and the monitored traffic will be copied to port e 2/6,
the mirror port.
Syntax: [no] mirror-port ethernet <port> [input | output]
Syntax: [no] config-trunk-ind
Syntax: [no] monitor ethernet <port> both | in | out
The <port> variable for mirror-port ethernet specifies the port to which the monitored traffic will be
copied. The <port> variable for monitor ethernet specifies the port on which traffic will be
monitored.
Specify the <port> variable in the following formats:
• PowerConnect B-Series FCX stackable switches – <stack-unit/slotnum/portnum>
The input or output parameters configure the mirror port exclusively for ingress or egress traffic. If
you do not specify one, both types of traffic apply.
The config-trunk-ind command enables configuration of individual ports in the trunk group. You
enter the config-trunk-ind command only once in a trunk group. After you enter the command, all
applicable port configuration commands apply to individual ports only.
NOTE
If you enter no config-trunk-ind, all port configuration commands are removed from the individual
ports and the configuration of the primary port is applied to all the ports. Also, once you enter the
no config-trunk-ind command, the enable, disable, and monitor commands are valid only on the
primary port and apply to the entire trunk group.
The both, in, and out parameters specify the traffic direction you want to monitor on the mirror port.
There is no default.
To display the port monitoring configuration, enter the show monitor and show mirror commands.
