Hi

When the bandwidth is high / spike, how can I be easy way to identify
the traffic coming from in juniper/netscreen

In linux, I can run the iftop -i int

Thank you

I really like the "monitor interface traffic" screen.


It's a little app that loops over writing out some columnnar statistics on interface rates and link states, clears the screen, and repeats.

Cheers,
jof

At least on my EX3200s running 10.1+, there is an "iftop", available
from a 'start shell tcsh' or similar.. I have no idea about netscreens,
so my apologies if this is irrelevant :)

Also available is 'ifmon', which is sort of a realtime 'show interface'
view, both are located in /usr/sbin.

Hello,

If you want to monitor a 10G interface for example xe-1/1/0

You can use : monitor interface xe-1/1/0
