# SNMP::Info::Layer2::HP(3pm)

SNMP Interface to HP Procurve Switches

## 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,
                          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(...);
```

## Change Log

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

- $hp-\>**cpu()**

  Returns CPU Utilization in percentage.

- $hp-\>**log()**

  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-\>**mem\_total()**

  Return bytes of total memory

- $hp-\>**mem\_used()**

  Returns bytes of used 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 :
