SNMP::Info::Layer2::HP(3) SNMP Interface to HP Procurve Switches


Max Baker


# 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";


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


Required MIBs

Included in V2 mibs from Cisco
(this MIB new with SNMP::Info 0.8)

The last four MIBs listed are from HP and can be found at <> or <>

Change Log

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


These are methods that return scalar value from SNMP
Returns CPU Utilization in percentage.
Returns all the log entries from the switch's log that are not Link up or down messages.
Returns bytes of free memory
Return bytes of total memory
Returns bytes of used memory
Returns the model number of the HP Switch. Will translate between the HP Part number and the common model number with this map :

Returns hp
Tries to use os_version() and if that fails will try and cull the version from the description field.
Returns serial number if available through SNMP
Returns number of entries in $hp->e_name that have 'slot' in them.
Returns fan status
Power supply 1 status
Power supply 2 status
Power supplied by PoE ports, in milliwatts ("hpicfPoePethPsePortPower")
Returns what version of STP the device is running. ("hpicfBridgeRstpForceVersion" with fallback to inherited stp_ver())

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


Uses $hp->i_description()
Returns reference to map of IIDs to current link duplex.
Returns reference to hash of IIDs to admin duplex setting.
Returns reference to hash of IIDs to HP specific port type ("hpSwitchPortType").
Crosses i_name() with $hp->e_name() using $hp->e_port() and i_alias()
Returns reference to hash of power Ethernet port table entries map back to interface index (c<ifIndex>)
Returns a HASH reference mapping from slave to master port for each member of a port bundle on the device. Keys are ifIndex of the slave ports, Values are ifIndex of the corresponding master ports.

These are methods that provide SNMP set functionality for overridden methods or provide a simpler interface to complex set operations. See ``SETTING DATA VIA SNMP'' in SNMP::Info for general information on set operations.
