Create an Excluded Address in the Pool

You can use this option to specify a range of IP addresses that cannot be allocated for the client. The no form of the command deletes the excluded pool.

In this example, the range of excluded address pools is 12.0.0.1 through 12.0.0.10. The first available IP in this pool will be 12.0.0.11.

1. Create the address pool.

   SEFOS# configure terminal
   SEFOS(config)# ip dhcp pool 1
   

2. Specify the excluded address pool.

   SEFOS(dhcp-config)# excluded-address 12.0.0.1 12.0.0.10
   SEFOS(dhcp-config)# end
   

3. View the excluded address pools.

   SEFOS# show ip dhcp server pools
   

   The output in switch 1 is:

   Pool Id                         : 1

   Exclude Address Start IP        : 12.0.0.1
