TCPDump Error

Ajinkya.Purohit

Level 1

Hi Folks

 

I need an explanation in this regards. I am using Ge0/0 and Ge0/1 as WAN Ports and Ge0/3 as LAN Port on Cloud vEdge. Ge0/2 has been received for Local Internet link.

 

Now, the LAN to LAN Routing works fine but I am not able to capture the TCPDump output of port Ge0/3. So also this port is not visible under ifconfig output.

Please try the same command specifying VPN 1 :

tcpdump vpn 1 interface ge0/3

By default the tcpdump will get executed for VPN 0 whilst your interface is present under VPN 1.
