Client stuck in DHCP REQD, not receiving discovery or boot requests?

Lost & Found
Level 2
Level 2

Although I've seen multiple cases of clients becoming stuck in "DHCP REQD," in my case, it appears from the debug output that there have been no discovery or BOOTREQUEST from the client (which should be?).

 

We are using 8.0.152.0, I want to find out if this behavior is due to a bug. Or is there a problem with APs? or do certain parameters need to be checked? Thanks

 - You can have these debugs analyzed with https://cway.cisco.com/wireless-debug-analyzer/  , for the rest if controller and ap-models permit suggest looking into : https://www.cisco.com/c/en/us/support/docs/wireless/wireless-lan-controller-software/200046-tac-recommended-aireos.html  , go as far up as you can go (8.0.x is old)

-- Each morning when I wake up and look into the mirror I always say ' Why am I so brilliant ? '
    When the mirror will then always repond to me with ' The only thing that exceeds your brilliance is your beauty! '

Did you check with different types of clients to see if all behave the same?

I do not suspect it is a bug. Need to check client vlan has been properly trunked to WLC (assuming local mode AP) & dynamic interface on WLC configured with correct IP/mask
