GLOBALS

These are methods that return scalar value from SNMP.

$cnos->mac(): Returns base mac based on "dot1dBaseBridgeAddress".
$cnos->os_ver(): Returns the OS version extracted from "entPhysicalSoftwareRev.1".

Overrides

$cnos->vendor(): Returns 'lenovo'.
$cnos->os(): Returns 'cnos'.

TABLE ENTRIES

These are methods that return tables of information in the form of a reference to a hash.

$cnos->agg_ports_cnos(): placeholder function, will return agg_ports mapping once implemented.

Overrides

$cnos->i_description(): Uses "ifName" to match most other devices.
$cnos->i_name(): Uses "ifDescr" to match most other devices.
$cnos->i_speed(): CNOS does not set "ifSpeed" to 4294967295 for high speed links, return orig_if_speed_high() instead. SNMP::Info will handle this correctly.
$cnos->i_speed_raw(): If "ifSpeedHigh" > 2500 we overwrite i_speed_raw(), using the formula: "ifSpeedHigh" * 1_000_000.
