I want to sniff the traffic from a computer connected to a remote switch.
The sniffer is installed on a computer connected to a TRUNK port with several sub-interfaces for each VLAN.
I want to direct the traffic to one of the sub-interfaces.
I tried using the "ingress" command and "learning" but the computer stopped working each time.
Remote source switch:
monitor session 3 source interface Gi7/1
monitor session 3 destination remote vlan 555
1. the computer port configuration:
switchport access vlan 20
switchport trunk encapsulation dot1q
switchport trunk native vlan 20
switchport mode trunk
logging event link-status
no snmp trap link-status
2.monitor session config:
monitor session 1 source vlan 555
monitor session 1 destination interface Gi10/22 ingress vlan 20 learning
Thanks in advanced for the help!!
I dont mind that the of the sub-interface destination port will only sniff the traffic.
