SNMP::Info::DocsisCM - SNMP Interface for DOCSIS Cable Modems | ||
=head1 DESCRIPTION | ||
SNMP::Info::DocsisCM is a subclass of SNMP::Info that provides info | ||
about a given cable modem. Extracts data from the sysDescr, which is | ||
mandated in the DOCSIS specification to match | ||
"HW_REV: <value>; VENDOR: <value>; BOOTR: <value>; SW_REV: <value>; MODEL: <value>" | ||
=head2 Inherited Classes | ||
None. | ||
=head2 Required MIBs | ||
None. | ||
=head1 GLOBALS | ||
These are methods that return scalar value from SNMP | ||
=over | ||
=item $cm->vendor() | ||
Returns the vendor of the cable modem. | ||
=item $cm->model() | ||
Returns the model of the cable modem. | ||
=item $cm->os() | ||
Returns 'cm', as the actual os is vendor and model dependent. | ||
=item $cm->os_ver() | ||
Returns the version of the software, extracted from the SW_REV field. | ||
