Cisco Switches, some ports show no status in GUI

Checkmk Raw Edition 2.2.0p14 on Ubuntu 22.04

On one 52 port switch the status of four ports is missing in GUI. The good ports show service description “Interface CLIENT PORT 10148”, the bad ones like “Interface ZH-HQ-AP006” (trailing Cisco Interface Number “10141” is missing). All ports that have this problem seem to have this formatting bug as well.

The port status is ONLY missing in GUI. It is shown in the CheckMk network inventory and in the cmk command output and in the SNMP walk log.

The trailing number is only shown if a port name exists more than 1 time.
Your ports with the ZH names are unique names and so no number is appended.
If you say you don’t see the ports inside the GUI, is this also the case after you activated all changes if there are any pending ones?

There are no pending changes.

I did also try “Tabula rasa” and recreating one of the switches. This did not resolve the issue.

In your output the checks are found and shown. What is the problem inside the GUI if you compare it to your posted output from the command line.

The GUI shows this:
cmk_swint_pend

All switches together we have around 110 stale services, but only in the GUI.

The age of the current service state (empty)
The time since the last check of the service (empty)
The time of the next scheduled service check (empty)
The last time the service was OK (empty)
Host created at: 2021-06-14 17:17:01

That means the service is found but got no data for the checks.
I think the most possible problem are the special characters in your port description.

Yes, it works, if I replace * with - on the problem interfaces.
Strangely the other interfaces with * cause no problems.

The interface “Interface MANAGEMENT [Vlan1], (up), MAC: 70:0B:4F:B3:A2:C0, Speed: 1 GBit/s, In: 3.64 kB/s (<0.01%), Out: 5.52 kB/s (<0.01%)” is still pending and no special characters. But I could disable this service, if there is no other solution.
