Bill Fenner and Zoltan Erszenyi,

Hacked in LLDP support from Baystack.pm by

=head1 SYNOPSIS
|

|
||||
# Let SNMP::Info determine the correct subclass for you.
|

|

=head1 DESCRIPTION
|
||||
|
||||
Provides abstraction to the configuration information obtainable from a
|
||||
Netgear device through SNMP. See inherited classes' documentation for
|
||||
inherited methods.
