A source port may only be monitored by one destination port (Message 3), but a destination port may
monitor more than one source port.
Message 3 One Destination Port in a Monitoring Session Error Message
% Error: Exceeding max MG ports for this MD port pipe.
Message 4 One Destination Port per Source Port Error Message
% Error: MD port is already being monitored.
FTOS Behavior: All monitored frames are tagged if the configured monitoring direction is transmit
(TX), regardless of whether the monitored port is a Layer 2 or Layer 3 port.
- If the source port is a Layer 2 port, the frames are tagged with the VLAN ID of the VLAN to which the
port belongs.
- If the source port is a Layer 3 port, the frames are tagged with VLAN ID 4095.
- If the source port is in a Layer 3 VLAN, the frames are tagged with the corresponding Layer 3 VLAN
ID.
For example, in the configuration source tengig 1/1 destination tengig 1/41 direction tx, if the source
port 1/1 is an untagged member of any VLAN, all monitored frames that the destination port 1/41
receives are tagged with the VLAN ID of the source port.
