Hi Aarón,
your right this a strange behavior. Down you can find the outputs of the commands your mention above. For Troubleshooting with the support, I change the transceiver from 1/1/11 to 1/1/12 and configurated it as a L2 interface. So, in included 1/1/11 and 1/1/12 in the output.

Hi again Florian,
It is rather a strange behaviour. I didn't notice that you preconfigured this: system interface-group 1 speed 10g.
Checking this link may help -> https://community.arubanetworks.com/community-home/digestviewer/viewthread?MID=27911 It explains what the interface-group does and how to troubleshoot it. The interesting commands (to run in the 8325) are:
sh system interface-group
sh int brief
Also on both switches show run interface xxx (with the involved ports) and give us the output to check it out.
If nothing interesting comes out of it I would recommend you upgrading to the latest availabla firmware and then performing a zeroize to have a totally clean and fresh install.
If it's on a production environment bare in mind that this takes a long time (20 minutes iirc). It would not be the first time that zeroizing a switch resolves issues as it may have come with some faulty configs (system wise) from factory.
Hope you can find out the issue!
Cheers,
Aarón

Hi Aarón,
Unfortunately, the problem is still accruing.
Thank you for your successes but I try it with different cable and transceiver and it still is not working.
But if I try to connect the 8325 to a 2510 with the same cable and transceiver with are not working to the 5406 I get a link right away. Same if I try the connection from the 5406 to the 2510 or another switch with the same cable and transceiver is just works.
I opened a case with the support but so far, I got no solution from there.

Hello Florian,
You probably already have figured it out but just in case here are my two cents. In your case only the port of the 8325 is up, that indicates that the light emitted by the 8325 through the fiber optic is not reaching the 5406, probably due a faulty fiber or tranceiver.
To validate this simply change the order of splices of fiber, in the 8325 put the Rx cable to Tx and viceversa and do the same on the 5406, if now the 5406 B21 port comes up that means that you have a faulty cable.
To check if the transceivers are ok, make a physical loopback with a single LC-LC cable, plug Rx and Tx on the same transceiver, if the port does not not come up then there is an issue with the transceiver.
Also check the Rx signal on the 5406 side:
show interf B21 transceiver details -> this will show you if there is any light reaching the port or not
I hope this helps.
Cheers,
Aarón

Hi Florian, few more show ... commands? like, as example, show interface 1/1/11 transceiver detail (on the Aruba 8325)? a similar command on the HP 5406zl? it's difficult to diagnose without a basic diagnostic.

HI @parnassus
Sorry my bad, you right I forgot to involve the interface on the 5406.
On the 5406 I use the Port B21 at the moment and on the 8325 it is the 1/1/11interface.
Actorly I don't use SFP+ modules, I use J4858D modules on both switches.
The right vlans are not set jet because the 5406 is in a productive environment so I use the default vlan to test the Link. The Trunk Ports belong to the Productive side of things and are working fine 😉

Hi @thi_flo!
It's not entirely clear to me what ports are really involved, especially watchin the HP 5406zl configuration you pasted.
Aruba 8325 side you wrote about 1/1/11 (operating at 10Gbps in routed mode). What's about on Aruba 5406 side? I doubt there is an HP 5406zl Module with 24 ports all operating at the same 10Gbps speed.
At best, IIRC, the old HP 5400zl supports these 10G (SFP+) modules only:
- HP ProCurve 2-Port SFP+/ 2-Port CX4 10-GbE yl Module (J9312A)
- HP ProCurve 4-Port 10GbE SFP+ zl Module (J9309A)
So, considering only SFP+ ports, there should be a module with 2 or 4 10Gbps SFP+ ports (and its SFP+ transceivers) with ports numbered Xn where X is the Slot letter and n is the port number...n=1-4...or something very similar).
Then you posted about Port Trunking logical interfaces Trk1 and Trk2 made of - I'm quite sure - 1Gbps RJ45 ports aggregated...this is a nonsense...I mean...(2x1Gbps) LACP or single 1Gbps ports on HP 5406zl side and a single 10Gbps Routed port on Aruba 8250 side...there is some confusion going on here.
Could you clarify a little bit better (ports, transceivers, vlan, etc.)?

I try to establish a connection over fiber between one of my HP5406 and an Aruba 8325.
The 8325 is showing that the Link is active but the 5406 is telling me the Link is down.
The 5406 is running Software Version K.16.02.0031
And the 8325 is running GL.10.04.3031
If try different GIBICs and different cables.
Below the Interface configurations

Has someone an idea how to resolve the issues?
