SNMP::...CiscoSB(3pm)

💖 SNMP::Info::Layer2::CiscoSB 💖

okay bestie, so this is the Perl module SNMP::Info::Layer2::CiscoSB — it's your SNMP interface to the Cisco Small Business series of switches. yes, the little ones. they're cute. they're also managed. let's go 🦋

✨ SYNOPSIS ✨

the vibe here is: let SNMP::Info figure out which subclass you actually need, because you are not about to guess manually 💅

# Let SNMP::Info determine the correct subclass for you.
my $ciscosb = new SNMP::Info(
                         AutoSpecify => 1,
                         Debug       => 1,
                         DestHost    => 'myswitch',
                         Community   => 'public',
                         Version     => 2
                       )
   or die "Can't connect to DestHost.\n";

my $class      = $ciscosb->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";

🎀 DESCRIPTION 🎀

This gives you an interface to all the SNMP data living on Cisco Small Business managed switches — and yes, "nee LinkSys", so if you're old enough to remember when they were LinkSys, hi, love you. basically it's for anything matching:

enterprises(1).cisco(9).otherEnterprises(6).ciscosb(1)

that OID right there is the vibe check. if your device matches it, you're home. 🏠✨

🌈 Inherited Classes

• SNMP::Info::CDP
• SNMP::Info::CiscoConfig
• SNMP::Info::CiscoStats
• SNMP::Info::EtherLike
• SNMP::Info::Layer2

📚 Required MIBs

• CISCOSB-DEVICEPARAMS-MIB
• CISCOSB-POE-MIB

🧬 Inherited Classes

and also all the MIBs that the inherited classes listed above need. you don't get to skip those, bestie, they're a package deal 🫶

👑 GLOBALS 👑

these are the methods that hand you back a scalar value straight from SNMP. little snack-sized facts about your switch.

• $ciscosb->mac() — returns the mac, pulled from "rndBasePhysicalAddress".
• $ciscosb->os_ver() — returns the software version, straight from "entPhysicalSoftwareRev".
• $ciscosb->serial() — returns the serial number of the unit, from "entPhysicalSerialNum".
• $ciscosb->model() — returns the model and the hardware revision of the unit, from "entPhysicalModelName+entPhysicalHardwareRev". yes, both, glued together, that's just how it is.

💅 Overrides

• $ciscosb->vendor() — returns 'cisco'.
• $ciscosb->os() — returns 'ros'.

🌟 Globals imported from SNMP::Info::Layer2

the details live in "GLOBALS" in SNMP::Info::Layer2 — go read that, it's giving thorough.

🌟 Globals imported from SNMP::Info::EtherLike

same deal, but for "GLOBALS" in SNMP::Info::EtherLike.

---

🌼 TABLE METHODS 🌼

• $ciscosb->peth_port_power() — the power being supplied by the PoE ports, measured in milliwatts. it comes from "rlPethPsePortOutputPower". no cap, your ports are out here feeding devices 🍓
• $ciscosb->i_duplex() — returns the duplex, and it figures that out based on whatever EtherLike->el_duplex() came back with. it's a chain, bestie, we respect the chain.

💅 Overrides

• $ciscosb->interfaces() — uses the i_name() field. that's the whole thing. simple. effective. periodt.

🌟 Table Methods imported from SNMP::Info::Layer2

see "TABLE METHODS" in SNMP::Info::Layer2 for the full rundown.

🌟 Table Methods imported from SNMP::Info::EtherLike

and see "TABLE METHODS" in SNMP::Info::EtherLike for all of that too 💜

---

heads up bestie: everything here is a straight-up interface to what's in those MIBs. if a device doesn't answer, that's a network problem, not a me problem 🙈
