Re: EX4300 LACP with SRX requires VSTP Edge configuration. Why.

Hi,

 

I have looked over these things without any findings that points me in the right direction.

show spanning-tree interface ae3 doesnt give me any output as long as I dont have it added under "protocols vstp ae3", as expected.

The show ethernet-switching interface ae3 shows all added VLANs as in FORWARDING.

host# run show ethernet-switching interface ae3
Routing Instance Name : default-switch
Logical Interface flags (DL - disable learning, AD - packet action drop,
LH - MAC limit hit, DN - interface down,
SCTL - shutdown by Storm-control,
MMAS - Mac-move action shutdown, AS - Autostate-exclude enabled)

Logical Vlan TAG MAC STP Logical Tagging
interface members limit state interface flags
ae3.0 65535 tagged
xxm 2 65535 Forwarding tagged
xxz 3 65535 Forwarding tagged
xxx 4 65535 Forwarding tagged
xxy 5 65535 Forwarding tagged

 

When I double checked this now, I experience the even more wierd thing, ping is forwarded to the SRX (it respond to ping) but I cannot reach it via SSH.

I have been trying to pinpoint this for days. LACP looks fine, but forwarding is sometimes working and sometimes not. When doing tests this morning, the "edge" command made it work. Without, it didnt work.

When testing now again, it works with and without.
