Customer Premises Equipment
Maximum Number of CPEs Determines the maximum number of CPE devices that can use the cable modem to
connect to the cable network. The default value is 1. In bridging mode, the
Cisco uBR924 router supports a maximum number of either 3 or 254 CPE devices,
depending on the Cisco IOS software release being used.
CPE Ethernet MAC Address Configures the cable modem with the MAC addresses for one or more CPE devices that
are allowed to connect to the cable network. Entering values in this field is optional
because the cable modem can learn the MAC addresses of CPE devices dynamically, up
to the maximum allowable number. However, DOCSIS cable modems give priority to the
CPE devices whose MAC addresses are in the configuration file.
Software Upgrade
TFTP Software Server IP
Address
Specifies the IP address for the TFTP server that will provide software images. This server
does not necessarily have to be the same TFTP server that provided the DOCSIS
configuration file.
Software Image Filename Specifies the fully qualified path name for the software image that the cable modem
should be running. If necessary, the cable modem uses TFTP to download this image from
the software server.
