Dhcp Server Cli Configuration - Avaya G250 Administration

Configuring the router
Overlap between pools is not allowed. You cannot configure a reservation pool on an
IP address that falls within the range of another pool.

DHCP server CLI configuration

1. Use the ip dhcp pool command, 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.
●
The start IP address and end IP address can be in the range of 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
and, for vendor specific options,
8. Repeat steps 1-7 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.
9. Activate each of the DHCP pools you configured, using the ic dhcp activate pool
command in general context, followed by the pool number.
10. Use the ip dhcp-server command to activate DHCP server. DHCP server is now
active. If you change the pool configuration, it is recommended to do so while the pool is
active.
