19 Port Monitoring The port monitoring feature allows you to monitor network traffic by forwarding a copy of each incoming or outgoing packet from one port to another port. Important Points to Remember • Port monitoring is supported on physical ports only. Port-channel interfaces and virtual local area networks (VLANs), are not supported. • The monitoring (destination, "MG") and monitored (source, "MD") ports must be on the same switch. • The monitored (source) interface must be a server-facing interface in the format slot/port, where valid slot number is 0 and server-facing port numbers are from 1 to 8. The monitoring interface must be an uplink port in the chassis. • Dell Networking OS permits a limited set of commands for monitoring ports. To display these commands, use 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 error is displayed as shown in example. Example Dell(conf)#mon ses 1 Dell(conf-mon-sess-1)#source tengig 0/1 destination tengig 0/6 direction both Dell(conf-mon-sess-1)#do show mon ses SessionID Source Destination Direction Mode Type 1 TenGig 0/1 TenGig 0/6 both interface Port-based Dell(conf-mon-sess-1)#mon ses 2 Dell(conf-mon-sess-2)#source tengig 0/1 destination tengig 0/7 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. 202
