🌸 SNMP::Info::EtherLike — bestie edition 💅

okay so this is a page from the User Contributed Perl Documentation, and the manual name up top is SNMP::...herLike(3pm) (yes it's truncated, the real one is SNMP::Info::EtherLike). Sit down, hydrate, we're learning ETHERLIKE-MIB together 🫶

🎀 SYNOPSIS 🎀

here's the whole vibe, copy-paste ready, no cap:

my $el = new SNMP::Info (
                            AutoSpecify => 1,
                            Debug       => 1,
                            DestHost    => 'router',
                            Community   => 'public',
                            Version     => 2
                          );

my $class = $el->class();
print " Using device sub class : $class\n";

# Find the duplex setting for a port on a device that implements
# ETHERLIKE-MIB
my $interfaces = $el->interfaces();
my $el_index   = $el->el_index();
my $el_duplex  = $el->el_duplex();

foreach my $el_port (keys %$el_duplex){
   my $duplex = $el_duplex->{$el_port};
   my $iid    = $el_index->{$el_port};
   my $port   = $interfaces->{$iid};

   print "PORT:$port set to duplex:$duplex\n";
}

literally the entire flex in one snippet 😭🔥

💖 DESCRIPTION 💖

SNMP::Info::EtherLike is a subclass of SNMP::Info that supplies access to the ETHERLIKE-MIB used by some Layer 3 Devices such as Cisco routers. it's giving niche but essential.

See RFC 1398 for more details — go read it, it's right there, iykyk 📖

⚠️ Important, bestie: use or create a subclass of SNMP::Info that inherits this one. Do not use directly. like, do not. it says so. 🙈

🧬 Inherited Classes

None. she's independent, she's her own woman ✨

📚 Required MIBs

ETHERLIKE-MIB — that's the one, that's the whole list 💜

---

🌈 GLOBALS 🌈

These are methods that return scalar values from SNMP.

None — nothing here, empty, a void, an aesthetic empty room 🎀

---

🧚 TABLE METHODS 🧚

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

💅 ETHERLIKE STATS TABLE ("dot3StatsTable") 💅

• $el->el_index() — Returns reference to hash. Indexes Stats Table to the interface index (iid). 🦋
  • maps to ("dot3StatsIndex")
• $el->el_duplex() — Returns reference to hash. Indexes Stats Table to Duplex Status of port. ✨
  • maps to ("dot3StatsDuplexStatus")
• $el->el_chipset() — ("dot3StatsEtherChipSet")
• $el->el_coll_excess() — ("dot3StatsExcessiveCollisions")
• $el->el_coll_late() — ("dot3StatsLateCollisions")
• $el->el_coll_mult() — ("dot3StatsMultipleCollisionFrames")
• $el->el_coll_single() — ("dot3StatsSingleCollisionFrames")
• $el->el_error_alignment() — ("dot3StatsAlignmentErrors")
• $el->el_error_fcs() — ("dot3StatsFCSErrors")
• $el->el_error_cs() — ("dot3StatsCarrierSenseErrors")
• $el->el_error_frame() — ("dot3StatsFrameTooLongs")
• $el->el_error_mac_rec() — ("dot3StatsInternalMacReceiveErrors")
• $el->el_error_mac_xmit() — ("dot3StatsInternalMacTransmitErrors")
• $el->el_error_sqe() — ("dot3StatsSQETestErrors")
• $el->el_error_symbol() — ("dot3StatsSymbolErrors")
• $el->el_xmit_defer() — ("dot3StatsDeferredTransmissions")
• $el->el_coll_count() — ("dot3CollCount")
• $el->el_coll_freq() — ("dot3CollFrequencies")

yes bestie that's 18 methods, i counted, all accounted for, no skips, no cuts 👑

🪄 Data Munging Callback Subroutines 🪄

• $el->munge_el_duplex() — Removes 'Duplex' from the end of a string. teeny tiny little cleanup, so satisfying 🌸

and that's the whole page, we ate and left no crumbs 💖 the source is perl v5.40.1, dated 2026-02-28, and the manual name is SNMP::...herLike(3pm) — go forth and query your duplex settings, bestie 🦋✨🎀
