    Hi Ramdev, is there any wasy to test linkloop connectivity between 2 interfaces to check interface belongs to same VLAN? I am settip up bond so need to check which 2 interface are on same VLAN?

    ifconfig bond1

  8. Ramdev says:

    normally I do tcpdump on each interface , to watch the network segment broadcast it is receiving.

  9. Venkatesh says:

    Thanks Ramdev, how can i analyze tcpdump to check VLAN connectivity? What s/w can i use to read tcpdump o/p?

    In HP i do fairly simple

    #linkloop -i but in redhat not sure?
