Port Monitoring

The Aggregator supports multiple source-destination statements in a monitor session, but there may only be one destination port in a monitoring session.

There may only be one destination port in a monitoring session ( % Error: Only one MG port is allowed in a session. ).

The number of source ports the Dell Networking OS allows within a port-pipe is equal to the number of physical ports in the port-pipe (n). Multiple source ports may have up to four different destination ports ( Exceeding max MG ports for this MD port pipe.).

In the following examples, ports 0/1, 0/2, 0/3, and 0/4 all belong to the same port-pipe. These ports mirror traffic to four different destinations (0/9, 0/10, 0/11, and 0/12).

A source port may only be monitored by one destination port, but a destination port may monitor more than one source port.

Dell Networking OS Behavior: All monitored frames are tagged if the configured monitoring direction is transmit (TX), regardless of whether the monitored port (MD) is a Layer 2 or Layer 3 port.
  • If the MD port is a Layer 2 port, the frames are tagged with the VLAN ID of the VLAN to which the MD belongs.
  • If the MD port is a Layer 3 port, the frames are tagged with VLAN ID 4095.
  • If the MD port is in a Layer 3 VLAN, the frames are tagged with the respective Layer 3 VLAN ID.
For example, in the configuration source tengig 0/1 destination tengig 0/9 direction tx, if the source port 0/1 is an untagged member of any VLAN, all monitored frames that the destination port 0/9 receives are tagged with the VLAN ID of the source port.
