[c-nsp] DHCP Question

[Paul Stewart]

Hi there...

We provide static IP's to business customers on our wireless networks using IOS DHCP server.  Normally we just bind the mac address to an IP like this:

 

ip dhcp pool CustomerXXX
   host XXX.XXX.XXX.61 255.255.255.192
   client-identifier 0100.0d88.98a8.77
   default-router XXX.XXX.XXX.1
   dns-server 216.168.96.10 216.168.96.13
   domain-name nexicom.net


This works great in all locations except for one customer at an existing location.  Here's some output:

 

dis1-rtr-bh#sh ip dhcp binding

IP address       Client-ID/              Lease expiration        Type
                 Hardware address
XXX.XXX.XXX.26   0050.bac9.f875          Sep 25 2005 02:16 PM    Automatic

XXX.XXX.XXX.60   0050.bac9.f875          Infinite                Manual

I'm having an impossible time trying to get this particular customer (who's running a linux box on his side) bound to a static IP.  Whether I use client-identifier or host entry it will not bind and I'm puzzled why.  Above you can see this customer getting a dynamic address of xxx.xxx.xxx.26 while I have a bound entry for this customer at xxx.xxx.xxx.60

Here's the current config:

ip dhcp pool Custxxxx
   host XXX.XXX.XXX.60 255.255.255.192
   hardware-address 0050.bac9.f875
   default-router XXX.XXX.XXX.1
   dns-server 216.168.96.10 216.168.96.13
   domain-name nexicom.net


I've tried it this way and also using client-identifier which works everywhere else...

 

Thoughts?
