Table 167 RMON Alarm commands Command no rmon alarm show rmon alarm Description Deletes this alarm index. Displays the current RMON Alarm parameters. Command mode: All Port mirroring Port Mirroring is used to configure, enable, and disable the monitored port. When enabled, network packets being sent and/or received on a target port are duplicated and sent to a monitor port. By attaching a network analyzer to the monitor port, you can collect detailed information about your network performance and usage. Port mirroring is disabled by default. NOTE: See the "Troubleshooting tools" appendix in the HP GbE2c Ethernet Blade Switch for c-Class BladeSystem Application Guide for information on how to use port mirroring. The following table describes the Port Mirroring Configuration commands. Table 168 Port Mirroring Configuration commands Command Description [no] port-mirroring enable Enables or disables port mirroring. Command mode: Global configuration show port-mirroring Displays current settings of the mirrored and monitoring ports. Command mode: All except User EXEC Port-based port mirroring The following table describes the port-based Port Mirroring Configuration commands. Table 169 Port Mirroring Configuration commands Command port-mirroring monitor-port mirroring-port {in|out|both} no port-mirroring monitor-port mirroring-port no port-mirroring monitor-port show port-mirroring Description Adds the port to be mirrored. This command also allows you to enter the direction of the traffic. It is necessary to specify the direction because: • If the source port of the frame matches the mirrored port and the mirrored direction is ingress or both (ingress and egress), the frame is sent to the mirrored port. • If the destination port of the frame matches the mirrored port and the mirrored direction is egress or both, the frame is sent to the monitoring port. Command mode: Global configuration Removes the mirrored port. Command mode: Global configuration Deletes this monitor port. Command mode: Global configuration Displays the current settings of the monitoring port. Command mode: All except User EXEC Configuration Commands 138

the monitor port, you can collect detailed information about your network performance and usage. Port mirroring is
disabled by default.

•
If the destination port of the frame matches the mirrored
port and the mirrored direction is egress or both, the
frame is sent to the monitoring port.
Command mode:
