How to configure Port Monitoring / Mirroring on Dell Networking Force10 Switches

This article explains how to set up and verify Port Monitoring (Mirroring) on Dell Networking Force10 Switches.

Important things to Know

  • Port Monitoring is supported on both physical and logical interfaces like virtual area network (VLAN) and port-channel.
  • The monitored (the source) and monitoring ports (the destination) must be on the same switch.
  • In general, a monitoring port should have no ip address and no shutdown as the only configuration. A monitoring port also may not be a member of a VLAN.
  • There may only be one destination port in a monitoring session.
  • A Port monitoring session can have multiple source statements.
  • One Destination Port can be used in multiple sessions.

Configure Port Monitor Session



Force10# configure

Enter configuration mode.

Force10(conf)# interface te 0/2

Enter the destination port to be used for monitor session. Confirm that it has no configuration.

Force10(conf-if-te-0/2)# no switchport
Remove any Layer 2 that may be configured.

Force10(conf-if-te-0/2)# no ip address

Remove any ip address that may be configured.

Force10(conf-if-te-0/2)# no shutdown

Enable the port.


Leave the destination port interface.

Force10(conf)# monitor session 0

Set up and identify the session number. Range 0 - 65535.

Force10(conf-mon-sess-0)#source te 0/1 destination te 0/2 direction both

Set the source (the port you want to monitor). Set the destination (the port where you send the monitored packets). Set the direction (Both/Rx/Tx).

Verify Port Monitor Session
