Port Monitoring; Important Points To Remember - Dell PowerEdge M IO Aggregator Command Reference Manual

Port Monitoring

The Aggregator supports user-configured port monitoring. See
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).

Important Points to Remember

• Port monitoring is supported on physical ports only; virtual local area network (VLAN) and
port-channel interfaces do not support port monitoring.
• The monitored (source, MD) and monitoring ports (destination, MG) must be on the same switch.
• The monitored (source) interface must be a server-facing interface in the format slot/port, where the
valid slot numbers are 0 or 1 and server-facing port numbers are from 1 to 32.
• The destination interface must be an uplink port (ports 33 to 56).
• In general, a monitoring port should have
FTOS permits a limited set of commands for monitoring ports. To display these commands, use the

• 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

% 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.
