Configuring Port Monitoring - Dell S6100 Configuration Manual

VLAN, the frames are tagged with the respective Layer 3 VLAN ID. For example, in the configuration source TenGig 11/6/1 destination
TeGig 11/6/2 direction tx, if the MD port TenGig 11/6/1 is an untagged member of any VLAN, all monitored frames that the MG port TeGig
11/6/2 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 platform continues to mirror outgoing traffic even after an MD participating in spanning tree protocol
(STP) transitions from the forwarding to blocking.

Configuring Port Monitoring

To configure port monitoring, use the following commands.
1 Verify that the intended monitoring port has no configuration other than no shutdown, as shown in the following example.
EXEC Privilege mode
show interface
2 Create a monitoring session using the command monitor session from CONFIGURATION mode, as shown in the following example.
CONFIGURATION mode
monitor session
monitor session type rpm/erpm
type is an optional keyword, required only for rpm and erpm
3 Specify the source and destination port and direction of traffic, as shown in the following example.
MONITOR SESSION mode
source
Example of Viewing Port Monitoring Configuration
To display information on currently configured port-monitoring sessions, use the show monitor session command from EXEC
Privilege mode.
