Given these parameters, Figure 34-4 illustrates conceptually the possible port monitoring configurations on the S-Series. Message 2 One Destination Port in a Monitoring Session Error Message on S-Series % Error: Exceeding max MG ports for this MD port pipe. Message 3 One Destination Port per Source Port Error Message % Error: MD port is already being monitored. Figure 34-4.

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 te 6/0 destination te 6/1 direction tx, if the MD port Tengigabitethernet 6/0 is an untagged member of any VLAN, all monitored frames that the MG port Tengigabitethernet 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. 638 | Port Monitoring
