• The destination interface must be an uplink port (ports 9 to 12). • In general, a monitoring port should have no ip address and no shutdown as the only configuration; the Dell Networking OS permits a limited set of commands for monitoring ports. You can display these commands using the ? command. • A monitoring port may not be a member of a VLAN. • There may only be one destination port in a monitoring session. • A source port (MD) can only be monitored by one destination port (MG). If you try to assign a monitored port to more than one monitoring port, the following message displays: Dell(conf)#mon ses 1 Dell(conf-mon-sess-1)#source tengig 0/1 destination tengig 0/8 direction both Dell(conf-mon-sess-1)#do show monitor session SessionID Source 1 TenGig 0/1 Destination Direction Mode TenGig 0/8 both interface Type ---- Port-based Dell(conf-mon-sess-1)#mon ses 2 Dell(conf-mon-sess-2)#source tengig 0/1 destination tengig 0/8 direction both % Error: MD port is already being monitored. NOTE: There is no limit to the number of monitoring sessions per system, provided that there are only four destination ports per port-pipe. If each monitoring session has a unique destination port, the maximum number of session is four per port-pipe. Port Monitoring The Aggregator supports multiple source-destination statements in a monitor session, but there may only be one destination port in a monitoring session. There may only be one destination port in a monitoring session (% Error: Only one MG port is allowed in a session.). The number of source ports the Dell Networking OS allows within a port-pipe is equal to the number of physical ports in the port-pipe (n). Multiple source ports may have up to four different destination ports (Exceeding max MG ports for this MD port pipe.). In the following examples, ports 0/1, 0/2, 0/3, and 0/4 all belong to the same port-pipe. These ports mirror traffic to four different destinations (0/9, 0/10, 0/11, and 0/12).

Dell Networking OS Behavior: All monitored frames are tagged if the configured monitoring direction is transmit (TX), regardless of whether the monitored port (MD) is a Layer 2 or Layer 3 port.
