The DHCP server on our out of support 4500 stopped providing IPs to clients on the two interfaces we had it configured to do so.
Did not see anything in the logs, tried recreating the DHCP range and changed a few settings, but no joy.
So I reset to factory defaults, and I did not get an IP from the DHCP sever to run the inital config. Ran the config wizard, set a password and left all other settings default (which includes the DHCP server being enabled and providing IPs for clients on x), still no luck.
I'm thinking it's dead, but figured I would check and see if there were any other ideas before it hits the bin. Unclear if I can/should upgrade firmware (running 5.9.1.5-16, 5.9.1.8-10 is current.
