not sure wether this is a bug or not but when running 'show dhcp leases' on a WLC4402 (running 126.96.36.199) I get something like this back:
(Cisco Controller) >show dhcp leases
MAC IP Lease Time Remaining
00:21:6b:c2:f9:14 10.16.16.50 44 seconds
00:23:12:b0:e1:5b 10.16.16.51 1 second
00:17:f2:3f:02:9b 10.16.16.53 7 seconds
Considering that my leases are setup to be 86400sec it seems a bit strange. I've the feeling that this is a simple display bug wanted confirmation.
Thanks for insight,
