SNMP::Info::Layer2::Centillion - SNMP Interface to Nortel Centillion based ATM Switches

|
|
|
=head1 SYNOPSIS
|
|
|
|
# Let SNMP::Info determine the correct subclass for you.
|
|
my $centillion = 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 = $centillion->class();
|
|
print "SNMP::Info determined this device to fall under subclass : $class\n";
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Provides abstraction to the configuration information obtainable from a
|
|
Centillion device through SNMP.
|
|
|
|
For speed or debugging purposes you can call the subclass directly, but not after determining
|
|
a more specific class using the method above.
|
|
|
|
my $centillion = new SNMP::Info::Layer2::centillion(...);
|
|
|
|
Note: This class supports version 4.X and 5.X which are VLAN based rather
|
|
than bridge group based.
