Fix Recommendation

Enable the feature or configure the switch so that it is capable of capturing ingress and egress packets from any designated switch port for the purpose of monitoring a specific user session.

The example configuration below will capture packets from interface GigabitEthernet0/3 and replicate the packets to GigabitEthernet0/2:

SW1(config)#monitor session 1 source int g0/3
SW1(config)#monitor session 1 destination int g0/2

Check Contents

Verify that the switch is capable of capturing ingress and egress packets from any designated switch port for the purpose of monitoring a specific user session.

The example configuration below will capture packets from interface GigabitEthernet0/3 and replicate the packets to interface GigabitEthernet0/2:

monitor session 1 source interface Gi0/3
monitor session 1 destination interface Gi0/2

If the switch is not capable of capturing ingress and egress packets from a designated switch port, this is a finding.
