SYNOPSIS

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

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

DESCRIPTION

SNMP::Info subclass to provide information for Cisco Catalyst series switches running CatOS.

This class includes the Catalyst 2920, 4000, 5000, 6000 (hybrid mode) families.

This subclass is not for all devices that have the name Catalyst. Note that some Catalyst switches run IOS, like the 2900 and 3550 families. Cisco Catalyst 1900 switches use their own MIB and have a separate subclass. Use the method above to have SNMP::Info determine the appropriate subclass before using this class directly.

See SNMP::Info::device_type() for specifics.

Note: Some older Catalyst switches will only talk SNMP version 1. Some newer ones will not return all their data if connected via Version 1.

For speed or debugging purposes you can call the subclass directly, but not after determining a more specific class using the method above.

 my $cat = new SNMP::Info::Layer2::Catalyst(...);

Inherited Classes

SNMP::Info::Layer2
SNMP::Info::CiscoVTP
SNMP::Info::CiscoStack

Required MIBs

Inherited Classes' MIBs

See SNMP::Info::Layer2 for its own MIB requirements.

See SNMP::Info::CiscoVTP for its own MIB requirements.

See SNMP::Info::CiscoStack for its own MIB requirements.

These MIBs are found in the standard v2 MIBs from Cisco.

GLOBALS

These are methods that return scalar value from SNMP

$cat->os()

Returns 'catalyst'

$cat->os_ver()

Tries to use the value from SNMP::Info::CiscoStats->os_ver() and if it fails it grabs $cat->m_swver()->{1} and uses that.

$cat->vendor()

Returns 'cisco'

TABLE ENTRIES

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

Overrides

$cat->bp_index()

Returns reference to hash of bridge port table entries map back to interface identifier (iid)

Crosses (portCrossIndex) to (portIfIndex) since some devices seem to have problems with BRIDGE-MIB
