DHCP servers
The DHCP server feature can be enabled in a TransPort LR device to assign IP addresses and other
IP configuration to other hosts on the same local network. Addresses are assigned from a specified
pool of IP addresses. For a local network, the device will use the DHCP server that has the IP address
pool in the same IP subnet as the local network.
You can configure up to 10 DHCP servers.
When a host receives an IP configuration, the configuration is valid for a particular amount of time,
known as the lease time. After this lease time expires, the configuration must be renewed. The host
performs lease-time renewal automatically.
