Description (partial)

C9800 command 'show wlan <ID> client stats' outputs the info of another WLAN (and not the one of the ID used in the command) where WLAN-name starts with same name-characters and other special conditions (like amount of WLANs, order of the WLANs, and others).

Example where command is used to display client stats for WLAN ID-1, but WLC outputs info for WLAN ID-2:

C9800#show wlan summary

Number of WLANs: 2

C9800#show wlan id 1 client stats
Wlan Profile Name: atest123r, Wlan Id: 2
Current client state statistics:

- C9800 running 16.12.1 and probably other older and newer codes.
- Two WLANs with a name that starts with a similar name before specific characters.
- Trigger also depends on amount of WLANs or order of the WLANs.
