I want to configure a DHCP server on 2851 with 12.4.11T IOS version.
I created a dhcp database as written in http://www.cisco.com/en/US/products/sw/iosswrel/ps5207/products_feature_guide09186a008027fa7c.html#wp1027258
with the "origin file tftp...." command I associate the DHCP Pool with this static mapping file. The IOS parses the file correct and saves it to the DHCP Binding database excepting the DHCP Lease time.
The IOS allways saves infinite in the DHCP database but I want a lease duration of one day.
Has anyone a correct configuration? Please help!
