NAME

SNMP::Info::Layer2::HP - SNMP Interface to HP Procurve Switches

AUTHOR

Max Baker

SYNOPSIS

 # Let SNMP::Info determine the correct subclass for you. 
 my $hp = 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      = $hp->class();
 print "SNMP::Info determined this device to fall under subclass : $class\n";

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(...);

Inherited Classes

SNMP::Info::Layer2
SNMP::Info::Entity
SNMP::Info::MAU

Required MIBs

RFC1271-MIB

Included in V2 mibs from Cisco

HP-ICF-OID

(this MIB new with SNMP::Info 0.8)

The last three MIBs listed are from HP and can be found at http://www.hp.com/rnd/software or http://www.hp.com/rnd/software/MIBs.htm

ChangeLog

Version 0.4 - Removed ENTITY-MIB e_*() methods to separate sub-class - SNMP::Info::Entity

GLOBALS

These are methods that return scalar value from SNMP

Returns all the log entries from the switch's log that are not Link up or down messages.

$hp->mem_free()

Returns bytes of free memory

$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 :

              );
$hp->os()

Returns hp

$hp->os_bin()

hpSwitchRomVersion.0

$hp->os_ver()

Tries to use os_version() and if that fails will try and cull the version from the description field.

$hp->os_version()

hpSwitchOsVersion.0

$hp->serial()

Returns serial number if available through SNMP

$hp->slots()

Returns number of entries in $hp->e_name that have 'slot' in them.

$hp->vendor()

hp

TABLE METHODS

These are methods that return tables of information in the form of a reference to a hash.

Overrides

$hp->interfaces()

Uses $hp->i_description()

$hp->i_duplex()

Maps $hp->mau_index() with $hp->mau_link(). Methods inherited from SNMP::Info::MAU.

$hp->i_duplex_admin()

Maps $hp->mau_index() with $hp->mau_auto(), $hp->mau_autostat(), $hp->typeadmin(), and $mau_autosent(). Methods inherited from SNMP::Info::MAU.

$hp->i_name()

Crosses i_name() with $hp->e_name() using $hp->e_port() and i_alias()

$hp->i_type()

Crosses i_type() with $hp->e_descr() using $hp->e_port()

$hp->i_vlan()

Looks in Q-BRIDGE-MIB -- see SNMP::Info::Bridge

and for older devices looks in HP-VLAN.

$hp->bp_index()

Returns reference to hash of bridge port table entries map back to interface identifier (iid)

Returns (ifIndex) for both key and value for 1600, 2424, 4000, and 8000 models since they seem to have problems with BRIDGE-MIB
