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
