SNMP::Info::Layer2::HP - SNMP Interface to HP Procurve Switches
=head1 AUTHOR
Max Baker
=head1 SYNOPSIS
# Let SNMP::Info determine the correct subclass for you.
my $hp = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
DestHost => 'myswitch',
Community => 'public',
Version => 2
)
or die "Can't connect to DestHost.\n";
my $class = $hp->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";
=head1 DESCRIPTION
Provides abstraction to the configuration information obtainable from a
HP ProCurve Switch via SNMP.
Note: Some HP Switches will connect via SNMP version 1, but a lot of config
data will not be available. Make sure you try and connect with Version 2
first, and then fail back to version 1.
For speed or debugging purposes you can call the subclass directly, but not
after determining a more specific class using the method above.
my $hp = new SNMP::Info::Layer2::HP(...);
=head2 Inherited Classes
=over
=item SNMP::Info::Layer2
=item SNMP::Info::LLDP
=item SNMP::Info::MAU
=back
=head2 Required MIBs
=over
=item F<RFC1271-MIB>
Included in V2 mibs from Cisco
=item F<HP-ICF-OID>
(this MIB new with SNMP::Info 0.8)
=item F<STATISTICS-MIB>
=item F<NETSWITCH-MIB>
=item F<CONFIG-MIB>

The last four MIBs listed are from HP and can be found at
L<http://www.hp.com/rnd/software> or
L<http://www.hp.com/rnd/software/MIBs.htm>
=head1 Change Log
Version 0.4 - Removed F<ENTITY-MIB> e_*() methods to separate sub-class -
SNMP::Info::Entity
=head1 GLOBALS
These are methods that return scalar value from SNMP
=over
=item $hp->cpu()
Returns CPU Utilization in percentage.
=item $hp->log()
Returns all the log entries from the switch's log that are not Link up or
down messages.
=item $hp->mem_free()
Returns bytes of free memory
=item $hp->mem_total()
Return bytes of total memory
=item $hp->mem_used()
Returns bytes of used memory
=item $hp->model()
Returns the model number of the HP Switch. Will translate between the HP Part
number and the common model number with this map :
