SYNOPSIS

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

GLOBALS

$ciscostats->cpu()

Returns ios_cpu() or cat_cpu(), whichever is available.

$ciscostats->cpu_1min()

Returns ios_cpu_1min() or cat_cpu1min(), whichever is available.

$ciscostats->cpu_5min()

Returns ios_cpu_5min() or cat_cpu5min(), whichever is available.

$ciscostats->mem_total()

Returns mem_free() + mem_used()

$ciscostats->vendor()

'cisco'

$ciscostats->os()

Tries to parse if device is running 'IOS', 'CatOS', 'IOS-XE' or something else from description()

Available values:

'ios'          for Cisco IOS
'ios-xe'       for Cisco IOS XE
'ios-xr'       for Cisco IOS XR
'pix'          for Cisco PIX

'fwsm-admin'   for Admin context of multi-context FWSM
'fwsm-context' for Standard context of multi-context FWSM
'ace-admin'    for Admin context of ACE module
'ace-context'  for Standard context of ACE module (NB: No OS version
                    detection is available, but will be the same as it's
                    'ace admin')
