Configuring Global Settings

Setting the Dynamic Host Control Protocol (DHCP) Server

When a packet comes in from a user whose address includes an assigned gateway, the
PortMaster does not consult the forwarding table but forwards the packet to the
gateway address. If a gateway address is not assigned to a range, the range uses the
default gateway address of the IP pool. If the IP pool is not assigned a default gateway
address, no crossbar IP address is used and the PortMaster consults the forwarding table.

Setting a Named IP Pool Gateway

Use the following command to set a default gateway for the entire named IP pool:

Command> set ippool Name default-gateway Gateway

Always reset the pool when you make changes to the named IP pool.

Command> reset ippool

When a packet comes in from a user whose address includes an assigned gateway, the
PortMaster does not consult the forwarding table but forwards the packet to the
gateway address. If a gateway address is not assigned to a range, the range uses the
default gateway address of the IP pool. If the IP pool is not assigned a default gateway
address, no crossbar IP address is used and the PortMaster consults the forwarding table.

The default gateway functions as a crossbar IP address. See the PortMaster 4 Command
Line Reference for details about how to configure crossbar IP for an interface, user, or
location.

Setting Named IP Pools in RADIUS

You must modify the RADIUS dictionary to enable named IP pools. You cannot
configure the local user table on the PortMaster for named IP pools. To enable named IP
pools, add the following line to the RADIUS dictionary:

ATTRIBUTE Ip-Pool-Name 193 string

The following example shows a RADIUS user profile using an IP pool named livermore:

homers Password = "kwyjibo"
Service-Type = Framed-User,
Framed-Protocol = PPP,
Framed-IP-Address = 255.255.255.254,
Framed-IP-Netmask = 255.255.255.255,
Ip-Pool-Name = livermore

Setting the Dynamic Host Control Protocol (DHCP) Server

The set dhcp server command supports the Cable Modem Telephone Return Interface
Specification (CMTRIS) developed by the Multimedia Cable Network System (MCNS)
Partners Limited. The CMTRIS solves the problem of limited upstream bandwidth in a
cable modem system by providing for the use of a standard telephone interface for
upstream traffic. Downstream traffic travels on the coaxial cable.
