4 Press the TAB key to save the settings.
Table 159 LAN Scope Specific Options
Attribute Description
Name Allows you to specify the name of the LAN scope.
Description Allows you to specify a description for the LAN scope.
DNS Server Allows you to specify the IP addresses of the primary DNS server and the secondary DNS
server in a valid dot format. When you specify a secondary DNS server, separate the two IP
addresses by a space.
Business Communications Manager automatically assigns the value for this parameter. If the
IP address or subnet mask for the corresponding LAN interface changes, this value is
overwritten. Use caution when changing this value.
WINS Server Allows you to specify the IP address of the WINS server.
Business Communications Manager automatically assigns the value for this parameter. If the
IP address or subnet mask for the corresponding LAN interface changes, this value is
overwritten. Use caution when changing this value.
Default Gateway Allows you to specify the IP address of the default next-hop router.
Business Communications Manager automatically assigns the value for this parameter. If the
IP address or subnet mask for the corresponding LAN interface changes, this value is
overwritten. Use caution when changing this value.
Lease Time Allows you to specify the time, in seconds, for an address assignment until the client’s lease
expires.
The default is 259200 seconds (72 hours).
Scope Status Allows you to enable or disable the scope.
The default is enabled.
Note: If the IP address or subnet mask for a LAN interface changes, the system creates or
modifies the corresponding DHCP scope for the interface. This operation also involves
setting
default values for some parameters. By default, Business Communications
Manager sets the IP address of the corresponding LAN interface to the DNS Server,
WINS Server, Default Gateway options of the scope. It also sets the lease time to three
days and creates a range of addresses for the scope. If the IP address of the LAN interface
is in the lower half of the subnet, the address range set for the scope includes all the
addresses above the LAN interface address. If the IP address of the LAN interface is in the
upper half of the subnet, the address range set for the scope includes all the addresses
below the LAN interface address. By default, the scope is enabled.
Note: When DNS is disabled in Business Communications Manager, the DNS Server box
must be set to the IP address of a remote DNS server.
