13 Port Monitoring The Aggregator supports user-configured port monitoring. See Configuring Port Monitoring for the configuration commands to use. Port monitoring copies all incoming or outgoing packets on one port and forwards (mirrors) them to another port. The source port is the monitored port (MD) and the destination port is the monitoring port (MG). Configuring Port Monitoring To configure port monitoring, use the following commands. 1. Verify that the intended monitoring port has no configuration other than no shutdown, as shown in the following example. EXEC Privilege mode show interface Dell(conf-if-te-0/1)#show config ! interface TenGigabitEthernet 0/1 no shutdown 2. Create a monitoring session using the command monitor session from CONFIGURATION mode, as shown in the following example. CONFIGURATION mode monitor session Dell(conf)#monitor session 1 Dell(conf-mon-sess-1)#source tengig 0/1 destination tengig 0/8 direction both 3. Specify the source and destination port and direction of traffic, as shown in the following example. MONITOR SESSION mode source Dell(conf)#monitor session 1 Dell(conf-mon-sess-1)#source tengig 0/1 destination tengig 0/8 direction both NOTE: By default, all uplink ports are assigned to port-channel (LAG) 128 and the destination port in a port monitoring session must be an uplink port. When you configure the destination port using the source command, the destination port is removed from LAG 128. To display the uplink ports currently assigned to LAG 128, enter the show lag 128 command. Port Monitoring 153
