17 Port Monitoring Overview 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. Monitoring Commands • description • monitor session • show config • show monitor session • show running-config monitor session • source (port monitoring) Important Points to Remember • Port monitoring is supported on physical ports only; virtual local area networks (VLANs) and port-channel interfaces do not support port monitoring. • 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 numbers are 0-1 and server-facing port numbers are from 1 to 32. The monitoring interface must be an uplink port in the chassis. • FTOS 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 (Message 1). Port Monitoring | 193
