VLAN trunk interface goes down after seconds

Hello,
I currently try to get a couple of Cisco Catalyst 9500 switches running.
I would like to connect two StackWise Virtual stacks via VLAN trunking to each other.
See this basic image of the network:
bb.png
After enabling one side get the VLAN trunk inferface up my whole network is not working for a few seconds until the link of the VLAN trunk interface goes down again. But the only thing I can see (on both StackWise switches) in logging is:
Jan 21 11:19:56.755: %LINK-3-UPDOWN: Interface HundredGigE1/0/28, changed state to down
 
Where can I dig deeper to get a more meaningful information? 
The interface state is simply down. No errdisabled or something like that...

I finally got it working... two problems I identified:

1. Both stacks had the same STP priority which lead to a short network outage at the beginning of each connection try

2. I used the wrong cables. The SFPs are for multi mode - I used single mode cables. Big mistake, but it happend...

Thanks to all for their help! I really appreciate it.

Hello @seb1303 

Do you check on both sides of the VLAN trunk interface ?  Verify that the interface settings (speed, duplex, VLAN configuration) match on both ends. A mismatch in configuration could lead to link instability.

The only think here is are you config same STP mode for both stack virtual SW?

Did you check STP ?

Did you see any log about stp?

What IOS XE code running both SVL - what is the Domain ID used on both the SVL (is this same ?)

check when you interconnect  2 SVL domain Id should be different  - there are some Layer 2 issue around.

Cisco StackWise Virtual Topology 

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9500/software/release/16-12/configuration_guide/ha/b_1612_ha_9500_cg/configuring_cisco_stackwise_virtual.html

 

After enabling one side get the VLAN trunk inferface up my whole network is not working for a few seconds until the link of the VLAN trunk interface goes down again.

we also need more information your spanning-tree information - how other 3rd party device participated in Layer 2 command, what you see the logs on both SVL ?

At the beginning both had the same domain id. I changed it. But the problems are still the same.

STP on HP infrastructure is disabled.

Change domain-id and first time you use same ! Here you need to stop

Can I see show spanning tree in both pairs before you interconnect via trunk?

What issue I think 

Domain-id use to build virtual mac for both SW this vMAC use in PO and for STP if you use same domain-id then both pairs use same vMAC and this make stp block the trunk.

Check show spanning tree  see the bridge id is it same or not 

If it same then you need to reboot one pair to make it select new vMAC for new different domain-id

Thanks

I rebooted the SVL after changing the domain ID.

Above output is for both. See the comment "SVL #1" and "SVL #2".
SVL #1 shows the bigger output. SVL #2 only shows "No spanning tree instance exists."

No spanning tree exists?

You mentioned that you disable stp for HP but I see you disable it for SVL #2

Show spanning tree summary <- share this for both SVL

Right, STP is disabled on the HP infrastructure. It is enabled on SVL #2 but there is currently no link on any interface so the output shows "No spanning tree instance exists.". As far as I know this is a normal behaviour. Isn't it?

(I shut down the port-channel of SVL #2 because this problem kills my whole networking...)

I don't know which member-port I need to use. But see what I get when I run this:
SVL #1

# test platform software nif_mgr lmp local-platform-info
Local Platform Information:
        Blueshift Version:1
        Distributed Stack Domain:1
        Distributed Stack Mode:1

        Stack MAC Address:3c8b:7f57:b2e0
        System CMI Index:0
        LMP Port LPN:0/0

SVL #2

# test platform software nif_mgr lmp local-platform-info

Address:3c8b:7f57:30e0

The stack mac is ok it different since domain is different 

Show lacp port-channel x 

In both pair 

Check the system mac address
