It's the SNMP::...Timetra(3pm) page, aka the User Contributed Perl Documentation situation, and we're gonna walk through it together. Grab a snack. 🍓

🦋 SYNOPSIS 🦋

Okay so the entire point is: you let SNMP::Info figure out which subclass this poor device belongs to, so you don't have to guess.

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

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

That or die is doing the Lord's work, do not remove it. 😭

🌈 DESCRIPTION 🌈

It's a subclass for Alcatel-Lucent Service Routers. That's the vibe. That's the whole assignment.

🫶 Inherited Classes

• SNMP::Info::Layer3

📚 Required MIBs

• TIMETRA-GLOBAL-MIB
• TIMETRA-LLDP-MIB
• TIMETRA-PORT-MIB
• TIMETRA-CHASSIS-MIB

🧚 Inherited Classes' MIBs

Yeah so, the parent class has its own needs. See "Required MIBs" in SNMP::Info::Layer3 for its own MIB requirements.

---

👑 GLOBALS 👑

These are the methods that return a scalar value from SNMP. Single values only, no table drama. ✨

• $alu->vendor() — Returns 'nokia'.
• $alu->os() — Returns 'TiMOS'.
• $alu->os_ver() — Grabs the version string from sysDescr.
• $alu->model() — Tries to combine series and model extracted from $alu->id() to one of the product MIBs.
  • Removes tmnxModel from the name for readability.
• $alu->fan() — Return the status of all fans from the TIMETRA-CHASSIS-MIB. Returns a string indicating the number of fans 'OK' or identification of any fan without a 'Ok' operating status.
• $alu->ps1_status() — Return the status of the first power supply in each chassis from the TIMETRA-CHASSIS-MIB.
• $alu->ps2_status() — Return the status of the second power supply in each chassis from the TIMETRA-CHASSIS-MIB.

There's more, but it lives at home. See documentation in "GLOBALS" in SNMP::Info::Layer3 for details.

💀 TABLE METHODS 💀

These are methods that return tables of information in the form of a reference to a hash. Hashes of hashes, the classic. 🧚

• $alu->i_duplex() — Returns reference to map of IIDs to current link duplex.
• $alu->i_duplex_admin() — Returns reference to hash of IIDs to admin duplex setting.
• $alu->agg_ports() — Returns a HASH reference mapping from slave to master port for each member of a port bundle on the device. Keys are ifIndex of the slave ports, Values are ifIndex of the corresponding master ports.

🔥 Overrides

• $alu->interfaces() — Returns ifName, since the default Layer3 ifDescr varies based upon the transceiver inserted.
• $alu->lldp_if() — Returns the mapping to the SNMP Interface Table. Utilizes (ifIndex) from the (tmnxLldpRemEntry ) index.

Not me pointing out that there is a literal trailing space inside that backtick-quoted tmnxLldpRemEntry . It's in the original, so it's staying. Character for character, bestie, that's the rule. 🙈

💖 LLDP Remote Table (lldpRemTable) uses

• (TIMETRA-LLDP-MIB::tmnxLldpRemTable)
• $alu->lldp_rem_id_type() — (tmnxLldpRemChassisIdSubtype)
• $alu->lldp_rem_id() — (tmnxLldpRemChassisId)
• $alu->lldp_rem_pid_type() — (tmnxLldpRemPortIdSubtype)
• $alu->lldp_rem_pid() — (tmnxLldpRemPortId)
• $alu->lldp_rem_desc() — (tmnxLldpRemPortDesc)
• $alu->lldp_rem_sysname() — (tmnxLldpRemSysName)
• $alu->lldp_rem_sysdesc() — (tmnxLldpRemSysDesc)
• $alu->lldp_rem_sys_cap() — (tmnxLldpRemSysCapEnabled)

🎀 Entity Table

• $alu->e_index() — (tmnxHwIndex)
• $alu->e_class() — Chassis, Module, Fan, Power Supply ...
  • (tmnxHwClass)
• $alu->e_descr() — Human Friendly
  • (tmnxHwName)
• $alu->e_fwver() — (tmnxHwFirmwareCodeVersion)
• $alu->e_fru() — BOOLEAN. Is a Field Replaceable unit?
  • (tmnxHwIsFRU)
• $alu->e_model() — Model Name of Entity.
  • (tmnxHwMfgBoardNumber)
• $alu->e_name() — More computer friendly name of entity.
  • (tmnxHwName)
• $alu->e_parent() — 0 if root.
  • (tmnxHwContainedIn)
• $alu->e_pos() — The relative position among all entities sharing the same parent.
  • (tmnxHwParentRelPos)
• $alu->e_serial() — (tmnxHwSerialNumber)
• $alu->e_swver() — (tmnxHwSoftwareCodeVersion)

Again — the parent class has lore. See documentation in "TABLE METHODS" in SNMP::Info::Layer3 for details.

🍓 Data Munging Callback Subroutines 🍓

These ones clean up the messy strings so they don't give you the ick. ✨

• $alu->munge_tmnx_state() — Removes 'deviceState' or 'device' from TmnxDeviceState strings.
• $alu->munge_tmnx_e_class() — Attempts to normalize tmnxHwClass to an IANAPhysicalClass.
• $alu->munge_tmnx_e_swver() — Extracts the software version from tmnxHwSoftwareCodeVersion string.

And that's the whole page, no skips, no summarising, every last flag and MIB accounted for. 💖

Okay bye bestie, this one came to you courtesy of perl v5.40.1, dated 2026-02-28 — so yes, it's lowkey from the future, and honestly? Slay. 👑✨
