FTOS Behavior: On the C-Series, S-Series and Z-Series, 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 gig 6/0 destination gig 6/1 direction tx, if the MD port

gigabitethernet 6/0 is an untagged member of any VLAN, all monitored frames that the MG port

gigabitethernet 6/1 receives are tagged with the VLAN ID of the MD port. Similarly, if BPDUs are

transmitted, the MG port receives them tagged with the VLAN ID 4095. This behavior might result in a

difference between the number of egress packets on the MD port and monitored packets on the MG

6), but a destination port may
