Enabling Host Authorization for an IP Range of CPEs
Instead of adding individual static CPEs on a specific cable interface using the cable
host authorization cpe command, CPEs can be added automatically to the network
by specifying a start and end range of IP addresses. This function allows you to
specify a partial subnet by allowing CPEs on different cable interfaces to
automatically connect to a network.
Use the cable host authorization range command in Global Configuration mode to
define a range of CPE IP addresses that are allowed to be added to the host
authorization table (static IP table). Any CPE IP address within the specified start and
end IP address range is added to the host authorization table when a CPE joins the
network.
MOT(config)#
cable host authorization range {<
prefix
> <
prefix
>}
where:
prefix
is the start of the IP address range.
prefix
is the end of the IP address range.
For example:
MOT(config-if)#
cable host authorization range 150.42.19.100 150.42.19.109
Removing Host Authorization for an IP Range of CPEs
Use the no cable host authorization range command to remove the start and end IP
range of CPE addresses so that new CPEs trying to join the network (having an IP
address within the specified range) cannot be added to the host authorization table:
MOT(config)#
no cable host authorization range {<
prefix
> <
prefix
>}
A CPE with an IP address that is within the start and end range defined by the host
authorization range command that is currently connected remains in the host
authorization table until it is individually removed by the no host authorization
command, or if the BSR is reset.
Note: Up to 32 CPE IP address ranges can be defined for the BSR.
