Display the current pool configuration. ip dhcp server pool name network network /prefix-length Prefix-length Range: 17-31 show config Command Mode CONFIGURATION DHCP DHCP DHCP Once an IP address is leased to a client, only that client may release the address. FTOS performs a IP + MAC source address validation to ensure that no client can release another clients address. This is a default behavior, and is separate from IP+MAC Source Address Validation. Exclude Addresses from the Address Pool The DHCP server assumes that all IP addresses in a DHCP address pool are available for assigning to DHCP clients. You must specify the IP address that the DHCP server should not assign to clients. Task Command Syntax Exclude an address range from DHCP assignment. The exclusion applies excluded-address to all configured pools.
