=head1 NAME
SNMP::Info::Layer2::CiscoSB - SNMP Interface to Cisco Small Business series
=head1 AUTHOR
Nic Bernstein (shamelessly stolen from Max Baker's Aironet code)
=head1 SYNOPSIS
# Let SNMP::Info determine the correct subclass for you.
my $ciscosb = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
DestHost => 'myswitch',
Community => 'public',
Version => 2
)
or die "Can't connect to DestHost.\n";
my $class = $ciscosb->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";
=head1 DESCRIPTION
Provides interface to SNMP Data available on Cisco Small Business (nee LinkSys)
managed switches. [i.e. those matching enterprises(1).cisco(9).otherEnterprises(6).ciscosb(1)]
