  • 1.  what is this interface?

    Hi,

     

    for the first time ever I have created vlan tagged interfaces on an SRX today. After doing so, I see a strange interface unit that was automatically created by Junos. Can anyone explain to me what that is? terse interface list:

     

    ge-2/0/8.0 up down aenet --> reth8.0
    ge-2/0/8.32767 up down aenet --> reth8.32767

     

    unit 0 is the actual vlan interface, unit 32767 just appeared.

     

    Thanks

    Sascha

    Hi Sascha,

     

    The internal unit .32767 is created automatically and used internally to process 802.3ad (LACP) frames.

     

    You will see it on all ae interfaces, as well as reth (which internally are ae interfaces, and can use LACP bundling as well).

     

    I found a brief KB article on it.
