=head1 SYNOPSIS
|
|
|
|
# Let SNMP::Info determine the correct subclass for you.
|
|
my $entity = new SNMP::Info(
|
|
AutoSpecify => 1,
|
|
Debug => 1,
|
|
# These arguments are passed directly on to SNMP::Session
|
|
DestHost => 'myswitch',

=head1 DESCRIPTION
|
|
|
|
ENTITY-MIB is used by some Layer 2 devices like HP Switches and Aironet Access Points
|
|
|
|
Create or use a device subclass that inherit this class. Do not use directly.
|
|
|
|
For debugging purposes you can call this class directly as you would SNMP::Info
|
|
|
|
my $entity = new SNMP::Info::Entity (...);

|
|
|
=head2 Inherited Classes
