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.
Configuring Port Monitoring
Port monitoring (also referred as mirroring) monitors network traffic by forwarding a copy of incoming and outgoing packets
from a source port to a destination port on the same network router To configure port monitoring on the port extender, use
the following commands.
1 Display the running configuration of an interface.
EXEC Privilege mode
show running-config monitor session
2 Create a monitoring session using the command monitor session from CONFIGURATION mode, as shown in the following
example.
MONITOR SESSION mode
monitor session [session-ID] source interface | range destination interface direction {rx |
tx | both}
3 Specify the source and destination port and direction of traffic, as shown in the following example.
MONITOR SESSION mode
monitor session 1 source TenGigabitEthernet 0/2 destination TenGigabitEthernet 0/4 direction
rx
