SNMP::...::Cisco(3pm)

✨ NAME ✨

SNMP::Info::Layer3::Cisco — bestie, this is the SNMP Interface to L3 and L2+L3 IOS Cisco devices that aren't covered by the other classes, AND it's the base L3 Cisco class that all the other device-specific L3 Cisco classes build on top of. She's a foundational queen. 👑

(This page lives in the SNMP::...::Cisco(3pm) slot of the User Contributed Perl Documentation, iykyk.)

💅 SYNOPSIS 💅

okay so first you let SNMP::Info figure out the right subclass for you, because she's smart like that:

# Let SNMP::Info determine the correct subclass for you.
my $cisco = 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      = $cisco->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";

Then you just ask her what class she decided on and print it. That's it. Slay. ✨

🌸 DESCRIPTION 🌸

She's the subclass for Generic Cisco Routers running IOS, and she's also the base L3 Cisco class for all the other device-specific L3 Cisco classes. Like, the whole squad descends from her. 💜

🌈 GLOBALS 🌈

These are the methods that hand you back a scalar value straight from SNMP. Little single values, big energy. 💫

• $cisco->eigrp_id() — pulls "cEigrpAsRouterId". That's the whole thing, she's a simple girl. 💁
• $switch->cisco_comm_indexing() — returns 1 when the device is likely to need vlan indexing. How does she know? She checks "vtpVersion". Detective mode: activated. 🔍

👑 TABLE METHODS 👑

These ones don't do baby scalars — they return tables of information in the form of a reference to a hash. Full meals, not snacks. 🍓

• $cisco->eigrp_peers() — returns EIGRP peer IP addresses.

("cEigrpPeerAddr")

• $cisco->i_vlan() — returns a mapping between "ifIndex" and the PVID or default VLAN. Perfect for when you're like "which vlan is this interface even on??" 😭

💖 and that's the whole page bestie 💖

This one's served up fresh from perl v5.40.1, dated 2026-02-28, and it's the SNMP::...::Cisco(3pm) manual. Go poke a router, you got this. 🦋✨
