Configuring the DHCP server
Procedure
1. Enter ip dhcp pool, followed by a number from 1 to 32, to create a DHCP
pool.
2. Use the name command to configure the pool’s name.
3. Configure a range of available IP addresses that the DHCP server may assign to
clients, using start-ip-addr to set the start IP address of the range and end-
ip-addr to set the end IP address of the range.
Consider the following:
• For a manual/reservation pool, set identical IP addresses for the start and end
IP addresses
• The start IP address and end IP address must be on the same network
according to the subnet mask
• The start IP address must be lower than the end IP address
• The combined number of IP addresses in all pools must not exceed 256
addresses
• Both the start IP address and end IP address can be up to 223.255.255.255
• The start IP address and end IP address may not be network/broadcast
addresses according to the subnet mask
4. Use the subnet-mask command to configure the subnet mask of the pool.
5. Use the lease command to configure the lease period for IP address
assignment.
By default, the lease is eight days.
6. For a manual/reservation pool, use the client identifier command to reserve
the pool’s IP address for assignment to a specific client.
To configure a reservation, the start IP address and end IP address must be
identical. You cannot configure more than one reservation on a single pool.
7. Configure DHCP options for the pool, if required.
See
Configuring options on page 450 and, for vendor specific options, Configuring
vendor-specific options on page 451.
8. Repeat steps 1 to 7 to configure as many DHCP pools as you require.
You can configure up to 32 DHCP pools. By default, all pools are inactive until you
activate them. This enables you to modify each pool’s configuration without affecting
network devices.
