💖 SNMP::Info::Layer3::Lenovo 💖

okay bestie, gather round, because we're talking about SNMP::Info::Layer3::Lenovo — the SNMP interface to Lenovo switches running CNOS. yes, that CNOS. the Lenovo one. slay. 💅

This page lives in the User Contributed Perl Documentation corner of your man pages, and honestly? iconic.

🦋 SYNOPSIS 🦋

the classic "let SNMP::Info figure out which subclass you actually need" move:

# Let SNMP::Info determine the correct subclass for you.
use SNMP::Info;
my $cnos = new SNMP::Info(
                         AutoSpecify => 1,
                         Debug       => 1,
                         DestHost    => 'myrouter',
                         Community   => 'public',
                         Version     => 2
                       )
   or die "Can't connect to DestHost.\n";
my $class = $cnos->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";

literally just hand it the vibes (AutoSpecify => 1) and it goes and sniffs out the right subclass for you. main character energy fr fr ✨

🌸 DESCRIPTION 🌸

It's a subclass for Lenovo switches running CNOS. that's the whole assignment. she does it well. 💅

🌈 Inherited Classes

SNMP::Info::IEEE802dot3ad
SNMP::Info::Layer3

she's built different because she's built on those two. periodt.

🍓 Required MIBs

LENOVO-ENV-MIB
LENOVO-PRODUCTS-MIB

no MIBs, no info. these are non-negotiable bestie.

🧚 Inherited Classes' MIBs

See SNMP::Info::IEEE802dot3ad for its own MIB requirements.

See SNMP::Info::Layer3 for its own MIB requirements.

(go check those pages, they have their own whole list, we're not gonna duplicate it here 💀)

👑 GLOBALS 👑

these are methods that return scalar values straight from SNMP. one value, no table, just a little guy.

$cnos->mac() — returns the base mac, and she gets it from dot1dBaseBridgeAddress. the classic source. 💖
$cnos->os_ver() — returns the OS version, extracted from entPhysicalSoftwareRev.1. yes, specifically .1. don't ask, it's just where it lives.

🔥 Overrides

$cnos->vendor() — returns 'lenovo'. shocking, I know. 😭
$cnos->os() — returns 'cnos'. also shocking. the consistency?? we love to see it.

🎀 TABLE ENTRIES 🎀

these return tables of information, i.e. a reference to a hash. so much data. so much structure. obsessed.

$cnos->agg_ports_cnos() — placeholder function 🫠 it will return the agg_ports mapping once it's implemented. so like… not yet bestie. it's giving "coming soon". don't build your whole monitoring stack on it, ngl.

💅 Overrides

$cnos->i_description() — uses ifName, to match most other devices. consistency queen 👑
$cnos->i_name() — uses ifDescr, to match most other devices. again: consistency. we love her.
$cnos->i_speed() — CNOS does not set ifSpeed to 4294967295 for high speed links, so this returns orig_if_speed_high() instead. good news: SNMP::Info will handle this correctly. so you don't have to panic. breathe. 🧘
$cnos->i_speed_raw() — if ifSpeedHigh is > 2500, we overwrite i_speed_raw(), using the formula: ifSpeedHigh * 1_000_000. math? in my manpage? more likely than you think. ✨
