HI..

We have one AP 3500 series which not joined to the WLC. On the AP there are error

Hi @Leo Laohoo

How we can see the expiry of AP certificate? I see on some forum we can check by issuing show crypto pki certificates, but in y 3500 there are no show crypto command.

Because you typed "crypto" wrong.

If no one is going to properly read the Field Notice, there is nothing I can do.

The time and date is correct, we still have 24 APs joined to this WLC. Only 1 AP with that SN which not joined.
