  • 1.  monitoring vlan trafic on EX23000

    Posted 03-18-2021 13:50
    bonjour all, 
    I often use this command 
    > monitor interface traffic detail​
    to check the amount of trafic on each physical interface  of my 2300s, if it,s up or down ... absolutely love this monitoring command. 
    please suggest to me monitoring commands on an EX that will give me answers to the following questions,
    For example,  I want to ssh a switch and check quickly ...
    • what is the bps trafic on a particular logical interface ?
    • the amount of multicast vs unicast on a particular logical interface ?
    • what is the amount of trafic going in and out of a particular vlan ? 
    merci
    Michel

    Hi,

    I suggest to use SNMP to collect traffic statistics  for a particular interface.
    If you really want to use a CLI option you can use "monitor interface  <IFD>"

    The most immediate way I can think of to measure Unicast vs Multicast on a transit interface is to use ipv4 firewall filters with a term for unicast and another for multicast with a count and acccept action.

    Traffic in the VLAN, you can use a L2 firewall filter with the count+accept action and apply it to the bridge domain. The same kind of construct for the ipv4 FWF.


    Cheers
