Commands for DHCP
309
node type in Hex from 0 to FF.
Default: No client node type is specified by default.
Command Mode: DHCP Address Pool Mode
Usage Guide: If client node type is to be specified, it is recommended to set the client
node type to h-node that broadcasts after point-to-point communication.
Example: Setting the node type for client of pool 1 to broadcasting node.
Switch(dhcp-1-config)#netbios-node-type b-node
26.1.25 network-address
Command: network-address <network-number> [<mask> | <prefix-length>]
no network-address
Function: Sets 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: Configuring the assignable address in pool 1 to be 10.1.128.0/24.
Switch(dhcp-1-config)#network-address 10.1.128.0 24
26.1.26 next-server
Command: next-server <address1>[<address2>[…<address8>]]
no next-server
Function: Sets the server address for storing the client import file; the “no next-server”
command cancels the setting.
Parameters: <address1>…<address8> are IP addresses, in the decimal format.
Command Mode: DHCP Address Pool Mode
Usage Guide: This command configures the address for the server hosting client import
file. This is usually used for diskless workstations that need to download configuration
