Hi all,
in one of our sites, I'm having trouble getting an uplink working. Here's the situation:
The main switch is an aruba 2540.
One of the switches connected to it, is an Aruba 2930F 8-ports.
Both switches run on version
16.10.0016.When this 8-ports switch is connected to the 2540, the ports go down (=no link, leds out). It's not a bpdu protection thing, because they don't go "admin down" and there is no bpdu protection on any of these uplink ports - I checked that 100 times or so, also in the logs this is not there.
Here's the port config of the 8-ports switch:
interface 8
broadcast-limit 10
tagged vlan 40,42-44,46-47
untagged vlan 1
loop-protect
exit
Here's the port config of the 2540 switch:
interface 11
name "lab"
tagged vlan 40,42-44,46-47
untagged vlan 1
loop-protect
exit
When an unmanaged switch is connected in between the 2 Aruba's, all works like a charm.
None the other switches have this problem. I used a template - pushed by Airwave - to put the initial config on all switches in that site, so there should be no difference there - except for the vlans per port of course.
In the logs of the 2540, I just see port up/down, nothing more
In the logs of the 8-ports, I see a message for all vlans that they "Starved for a BPDU on port 8 from Desginated Bridge"
I tried the below already:
- use another port (on both switches)
- I asked our local guy to disconnect everything from the 8-ports switch and only connect the uplink
- disabled/enabled spanning tree
- removed spanning tree mode (rapid pvst)
- rebooted switch
- configured keep-alives on the uplink ports (tried on each side)
- bpdu filter
- broadcast limit
- ...
Nothing of the above worked
I'm out of ideas to try to get this working. Does anybody of you have more inspiration for me on this, please?
Thanks!
