Dell Networking OS Behavior: All monitored frames are tagged if the configured 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 configuration source TenGig 6/0 destination TenGig 6/1 direction tx, if the MD port TenGig 6/0 is an untagged member of
any VLAN, all monitored frames that the MG port TenGig 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 port.
Dell Networking OS Behavior: The switch continues to mirror outgoing traffic even after an MD participating in spanning tree
protocol (STP) transitions from the forwarding to blocking.
