Updated 8/20/2015, 7:55 pm: TSS has restored the server and the network team believes that normal DHCP service has been restored.

8/20/2015 1:25:58 PM:
DHCP is not working on various older Cisco switches on the UW campus. The problem is due to a bug on older Cisco switches that was discovered when a server failed that received log files from the affected switches. As a temporary fix, network personnel have disabled on the affected switches the writing of logs to the server. At the same time, IT staff are working on restoring the server. All known problems are resolved at this time. Users may need to do a DHCP release/renew to implement the temporary fix.
