Example of Viewing a Monitoring Session
In the example below, 0/25 and 0/26 belong to Port-pipe 1. This port-pipe has the same restriction of only four destination ports, new or
used.

Given these parameters, the following illustration shows the possible port monitoring congurations.
Figure 90. Port Monitoring Congurations
Dell Networking OS Behavior: All monitored frames are tagged if the congured monitoring direction is egress (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 conguration source Gig 6/1 destination Gig 6/2
