  • 1.  EX4200 - Clear arp

    Posted 02-01-2016 12:20

    We had a very strange issue today with the arp, in this EX4200.

     

    One of our servers was very unresponsive, even though the IP and mac showed up in the arp table,

    We had drops on pings.

     

    Once I cleared the arp, the response came back to normal.

     

    How often does the arp need to be cleaned.?

    Hi,

    By default, the ARP aging timer is set at 20 minutes

    Have you tried to change the ARP timer ?

    [edit system arp]
    aging-timer minutes;
