Dell PowerEdge FN I/O Module Command Line Reference Guide 9.10(0.0)

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.
