Functional Notes

The AOS

DHCP server (by default) allows all IP addresses for the DHCP p ool to be assigned to requesting

clients. This command is used to ensure that the specified addr ess is neve r assigne d by the DHCP server.

When static addressed hosts are present in the network, it is helpful to exclude the IP addresses of the

host from the DHCP IP address pool. This will avoid IP address overlap.
