5-4 Motorola RF Switch System Reference
5.2.1 Configuring the Switch DHCP Server
The switch contains an internal Dynamic Host Configuration Protocol (DHCP) Server. DHCP can provide the
dynamic assignment of IP addresses automatically. DHCP is a protocol that includes mechanisms for IP
address allocation and delivery of host-specific configuration parameters from a DHCP server to a host. Some
of these parameters are IP address, network mask and gateway.
When a DHCP server allocates an address for a client, the client is assigned a lease (which expires after an
interval defined by the administrator). Before the lease expires, clients are expected to renew the lease to
continue to use the addresses assigned. Once a lease has expired, the client to which that lease was
assigned is no longer permitted to use the leased IP address.
To configure DHCP:
1. Select Services > DHCP Server from the main menu tree.
2. Select the Enable DHCP Server checkbox to enable the switch’s internal DHCP Server for use with
global pools.
3. Select the Ignore BOOTP checkbox to bypass a BOOTP request.
4. Define an interval (from 1 -10 seconds) for the Ping timeout variable. The switch uses the timeout to
intermittently ping and discover whether the client requested IP address is already used.
NOTE: DHCP Server setting updates are only implemented when the switch is restarted.
NOTE: When using the switch’s internal DHCP server ensure that traffic can pass on UDP
ports 67 & 68 between the switch and the clients receiving DHCP information.
