    Hello.

    Wrong subject...

    A-side EX4500
    B-side EX4300

    I'm investigating a problem with one of two members of a aggregated Ethernet link where the backup link has suddenly started to timeout LACP packets. 

    Both switches has no CPU spikes at all and physical link is there is no problem with.

    Here's syslog output for A and B side.

    Any advice?

    Thanks.
