I have an interesting scenario that I can't explain. I'm looking at a
3640 router running as a DHCP server with a "standard" configuration -
no conflict logging, just a specified pool and an excluded range for
static addresses. No hard-coded MAC addresses or permanent entries.
Yet when I run a "show ip dhcp binding", I see several entries whose
lease expiration is listed as "infinite". I have the lease time set for
1 hour, and all of the other addresses are adhering to this
configuration. Why would some entries be listed as infinite? As far as
I know, the DHCP server dictates the least time, not the DHCP client.
Hmm... anyone have any clues? :-)
