Why certificate info has gone at wlc

[interfacedy]

Hello, We need configure certificate for vWLC9800 sometimes. The commands are like below:

WLC(config)#ap dot11 5ghz shutdown

WLC(config)#ap dot11 24ghz shutdown

WLC(config)#wireless management interface gig 1

WLC(config)#ap country US

WLC#wireless config vwlc-ssc key-size 2048 signature-algo sha256 password 0 abc

WLC#show wireless management trustpoint
Trustpoint Name : WLC_WLC_TP
Certificate Info : Not Available
Private key Info : Not Available
FIPS suitability : Not Applicable

After running these commands, the original info of certificate has gone. it become "Not Available"(original is Available). Did I miss some step or some step wrong? Anyone can explain commands briefly? Thank you

Verify your wireless management interface.

By default, the 9800-CL comes with three network interfaces:

●     GigabitEthernet1 -> Device management interface: Map it to the out-of-band management network. This is the equivalent of the service port.

●     GigabitEthernet2 -> Wireless management interface: Map it to your network to reach APs and services. Usually this interface is a trunk to carry multiple VLANs.

●     GigabitEthernet3 -> High Availability interface: Map it to a separate network for peer-to-peer communication for SSO.

Regards,

CJ

You should see some info, did you reboot the controller?

Its very strange. I often see the two below info, but dont know why it happen. Do you have any idea on that?  Thanks

Certificate Info : Not Available
Private key Info : Not Available

When I see what you have posted, its usually an issue with the trustpoint.  I basically delete it and create a new one.  The issue for me was on earlier code version, not the later ones.

I think this could be the issue. Try with vlan instead of gig int for wireless management and then do the cert creation.

C9800(config)#wireless management interface vlan X
