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, M1122 uses the default values for all DHCP parameters. The
default values are:
D Start address is the interface IP address
D Subnet mask 255.255.255.0
D Range size of up to 253 addresses starting from the interface IP
address.
D DNS address is the interface IP address
D Lease time is 60 minutes
D Domain 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.
