✨ SNMP::...illion(3pm) ✨

okay bestie, this is a page from the User Contributed Perl Documentation set — it's the man page for SNMP::...illion(3pm) (yes the name is abbreviated like that, we love a mystery 💅). let's get into it.

🌸 NAME 🌸

SNMP::Info::Layer2::Centillion — the SNMP interface to Nortel Centillion based ATM Switches. no cap, that's the whole vibe.

Eric Miller wrote this. iconic of him honestly.

✨ SYNOPSIS ✨

okay so here's how you actually use it. you let SNMP::Info figure out the right subclass for you, because why would you do that work yourself:

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

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

like, it just tells you what class your device falls under. main character energy tbh 👑

💖 DESCRIPTION 💖

This gives you an abstraction over all the configuration info you can pull off a Centillion device through SNMP. simple as that, fr fr.

Note: This class supports version 4.X and 5.X which are VLAN based rather than bridge group based. so if you're on the bridge-group flavor, this is not your girl, sorry bestie 😭

🌈 GLOBALS 🌈

these are the methods that return scalar values from SNMP. lil single-value girlies ✨

• $centillion->vendor() — returns 'nortel'
• $centillion->model() — cross references $centillion->id() to the SYNOPTICS-MIB and returns the results. also it removes "sreg-" from the model name (we don't need that baggage 🚮)
• $centillion->os() — returns 'centillion'
• $centillion->tftp_action() — ("sysTFTPStart")
• $centillion->tftp_host() — ("sysTFTPIpAddress")
• $centillion->tftp_file() — ("sysTFTPFileName")
• $centillion->tftp_type() — ("sysTFTPFileType")
• $centillion->tftp_result() — ("sysTFTPResult")

🌟 Overrides

• $centillion->index_factor() — required by SNMP::Info::SONMP. it's the number representing the number of ports reserved per slot within the device MIB. returns 256.
• $centillion->slot_offset() — required by SNMP::Info::SONMP. it's the offset if slot numbering does not start at 0. returns 0.

👑 TABLE METHODS 👑

these are the methods that return tables of info, in the form of a reference to a hash. multi-value baddies 💅

🌙 Overrides

• $centillion->interfaces() — returns a reference to the map between IID and physical Port.

Slot and port numbers on the Passport switches are determined by the formula:

 port = index % 256
 slot = int(index / 256)

The physical port name is returned as slot.port.

• $centillion->i_duplex() — returns reference to map of IIDs to current link duplex
• $centillion->i_duplex_admin() — returns reference to hash of IIDs to admin duplex setting
• $centillion->i_ignore() — returns reference to hash of IIDs to ignore.
• $centillion->fw_mac() — ("s5CmSNodeMacAddr")
• $centillion->fw_port() — ("s5CmSNodeIfIndx")
• $centillion->bp_index() — returns a mapping between "ifIndex" and the Bridge Table.
• $centillion->i_vlan() — returns a mapping between "ifIndex" and the VLAN.

🍓 Centillion 802.3 Extension Table ("cnDot3ExtnTable")

• $centillion->centillion_p_index() — returns reference to hash. maps table IIDs to Interface IIDs. ("cnDot3ExtnIfIndex")
• $centillion->centillion_p_duplex() — returns reference to hash. maps port operational duplexes to IIDs. ("cnDot3ExtnIfOperConnectionType")
• $centillion->rc_centillion_p_duplex_admin() — returns reference to hash. maps port admin duplexes to IIDs. ("cnDot3ExtnIfAdminConnectionType")

🌸 Centillion VLAN Table ("cnVlanPortMemberTable")

• $centillion->centillion_i_vlan_index() — returns reference to hash. Key: Table entry, Value: Index. ("cnVlanPortMemberIfIndex")
• $centillion->centillion_i_vlan() — returns reference to hash. Key: Table entry, Value: VLAN ID. ("cnVlanPortMemberVID")
• $centillion->centillion_i_vlan_type() — returns reference to hash. Key: Table entry, Value: VLAN Type. ("cnVlanPortMemberIngressType")

and that's the whole page bestie, no skips, no cuts, we read all of it 💖

okay bye ily — this bad boy ships as perl v5.40.1, dated 2026-02-28, and it lives under SNMP::...illion(3pm). slay 🎀✨
