Dell PowerEdge FN I/O Module Configuration Guide 9.10(0.0)

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
                                    

Example of Viewing Port Monitoring Configuration

To display information on currently configured port-monitoring sessions, use the show monitor session command from EXEC Privilege mode.

Dell(conf)# monitor session 0
                                 Dell(conf-mon-sess-0)# source tengig 0/1 dest tengig 0/8 direction rx
                                 Dell(conf-mon-sess-0)#exit
                                 Dell(conf)# do show monitor session 0
                                 SessionID Source     Destination   Direction  Mode       Type
                                 --------- ------      -----------  ---------  ----       ---- 
                                 0    TenGig 0/1   TenGig 0/8       rx     interface  Port-based
                                 Dell(conf)#
                              

In the following example, the host and server are exchanging traffic which passes through the uplink interface 0/1. Port 0/1 is the monitored port and port 0/8 is the destination port, which is configured to only monitor traffic received on tengigabitethernet 0/1 (host-originated traffic).
