[c-nsp] IOS DHCP Server - dynamic and static in one subnet

[Ramcharan, Vijay A]

Since you mentioned one subnet with static allocations from a portion of
that subnet I assume that you don't want the DHCP server handing out
your static allocations. You can configure exclusions (i.e. don't give
out these addresses) with "ip dhcp excluded-address"
