SYNOPSIS

 # Let SNMP::Info determine the correct subclass for you.
 my $cat = new SNMP::Info(
                          AutoSpecify => 1,
                          Debug       => 1,
                          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(...);

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'

$cat->cisco_comm_indexing()

Returns 1. Use vlan indexing.

TABLE METHODS

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