  • 1.  Can you see all traffic that is hitting a certain interface on the CLI or GUI?

    I know with the juniper that when you run a snoop or a flow filter the juniper displays traffic from all interfaces.

     

    However are device is being hit with a lot of broadcast traffic by the looks of it so we want to find out what address the main of this is coming from. Is the anyway on box to see all the traffic hitting an interface?

     

    Thanks Chris

    Hi Chris,

    you can set filters with snoop:

    test(M)-> snoop filter ?
    cisco-hdlc           snoop cisco hdlc protocol packet
    delete               delete snoop filter
    ethernet             snoop specified ethernet
    frame-relay          snoop frame relay protocol and multilink fragment packet
    id                   snoop filter id
    ip                   snoop ip packet
    off                  turn off snoop filter
    on                   turn on snoop filter
    ppp                  snoop ppp protocol and multilink fragment packet
    tcp                  snoop tcp packet
    udp                  snoop udp packet

     

    in your case you can select "ethernet".

     

    Hope it helps,

    Nadia
