M1112 Administrator Manual

Start address is the first address in the address range. The Range size defines how many addresses the range contains. Subnet mask is the subnet mask of the addresses in the range. Primary and Secondary DNSs set the domain name servers for the corresponding address range. Lease time defines how often the DHCP client must renew its lease. Domain name defines the domain name for the range.

The DHCP server can be enabled towards LAN and VBRIDGE (gateway interface) ports. When the DHCP server is enabled, up to two scopes (address ranges) are automatically generated and bound to LAN/VBRIDGE interfaces, in this order if the interface has an IP address. In Figure 5-6, scope (a) has been bound to Ethernet interface and scope (b) to VBRIDGE interface. When the address ranges are not defined, M1112 uses the default values for all DHCP parameters. The default values are:

DStart address is the interface IP address

DSubnet mask 255.255.255.0

DRange size of up to 253 addresses starting from the interface IP address.

DDNS address is the interface IP address

DLease time is 60 minutes

DDomain name is null string

If at least one address range has been defined, then IP address, DNS, domain name and lease time, if defined, override the default values.
