18.2.2.18 network-address
Command: network-address <network-number> [<mask> | <prefix-length>]
no network-address
Function: Set the scope for assignment for addresses in the pool; the ‘no
network-address’ command cancels the setting.
Parameters: <network-number> is the network number; <mask> is the subnet mask in
the decimal format; <prefix-length> stands for mask in prefix form. For example, mask
255.255.255.0 in prefix is ‘24’, and mask 255.255.255.252 in prefix is ‘30’. Note: When
using DHCP server, the pool mask should be longer or equal to that of layer 3 interface IP
address in the corresponding segment.
Default: If no mask is specified, default mask will be assigned according to the address
class.
Command mode: DHCP Address Pool Mode
Usage Guide: This command sets the scope of addresses that can be used for dynamic
assignment by the DHCP server; one address pool can only have one corresponding
segment. This command is exclusive with the manual address binding command
‘hardware address’ and ‘host’.
Example: Configure the assignable address in pool 1 to be 10.1.128.0/24.
Switch(dhcp-1-config)#network-address 10.1.128.0 24
