macaddress with lease expiration infinite

[hernanescalante]

hi. I have this DHCP configuration on a SW 6509...

!
ip dhcp excluded-address 10.132.98.1 10.132.98.10
!         
ip dhcp pool VLAN-WIFI
   network 10.132.98.0 255.255.255.192
   default-router 10.132.98.1
   dns-server 10.132.16.2 10.132.16.3
   domain-name xxx.com
   lease 0 4
!

When i look for the DHCP binding i get an IP with lease expiration infinite

SWITCH01#sh ip dhcp binding              
IP address       Client-ID/              Lease expiration        Type
                 Hardware address
10.132.98.22     bc3b.af21.bf3a          Infinite                Automatic
10.132.98.23     0140.6aab.3f47.d9       May 16 2014 01:01 PM    Automatic

Why is that??

Thanks

your config seems to be fine why donot your clear the binding and check again .unplug the computer and restart it then given this command to the switch

# clear ip dhcp binding *

and see if the new lease is what you expected.

thx

[hernanescalante]

do you know why that happens??

[kaaftab]

yes its due to binding was done before this config. and needs to be clear and only way for renew is either by force/request by client.
