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(...);

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()

Returns reference to map of IIDs to current link duplex.

$hp->i_duplex_admin()

Returns reference to hash of IIDs to admin duplex setting.

$hp->vendor_i_type()

Returns reference to hash of IIDs to HP specific port type (hpSwitchPortType).

$hp->i_name()

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

$hp->peth_port_ifindex()

Returns reference to hash of power Ethernet port table entries map back to interface index (c<ifIndex>)

Topology information

Based upon the firmware version HP devices may support Cisco Discovery Protocol (CDP), Link Layer Discovery Protocol (LLDP), or both. These methods will query both and return the combination of all information. As a result, there may be identical topology information returned from the two protocols causing duplicate entries. It is the calling program's responsibility to identify any duplicate entries and remove duplicates if necessary.

$hp->hasCDP()

Returns true if the device is running either CDP or LLDP.

$hp->c_if()

Returns reference to hash. Key: iid Value: local device port (interfaces)

$hp->c_ip()

Returns reference to hash. Key: iid Value: remote IPv4 address

If multiple entries exist with the same local port, c_if(), with the same IPv4 address, c_ip(), it may be a duplicate entry.

If multiple entries exist with the same local port, c_if(), with different IPv4 addresses, c_ip(), there is either a non-CDP/LLDP device in between two or more devices or multiple devices which are not directly connected.

Use the data from the Layer2 Topology Table below to dig deeper.

$hp->c_port()

Returns reference to hash. Key: iid Value: remote port (interfaces)

$hp->c_id()

Returns reference to hash. Key: iid Value: string value used to identify the chassis component associated with the remote system.

$hp->c_platform()

Returns reference to hash. Key: iid Value: Remote Device Type
