=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.

=head1 TABLE METHODS
These are methods that return tables of information in the form of a reference
to a hash.
=head2 Overrides
=over
=item $hp->interfaces()
Uses $hp->i_description()
=item $hp->i_duplex()
Returns reference to map of IIDs to current link duplex.
=item $hp->i_duplex_admin()
Returns reference to hash of IIDs to admin duplex setting.
=item $hp->i_name()
Crosses i_name() with $hp->e_name() using $hp->e_port() and i_alias()
=item $hp->i_vlan()
Returns a mapping between ifIndex and the PVID (default VLAN) or untagged
port when using HP-VLAN.
Looks in Q-BRIDGE-MIB first (L<SNMP::Info::Bridge/"TABLE METHODS">) and for
older devices looks in HP-VLAN.
=item $hp->i_vlan_membership()
Returns reference to hash of arrays: key = ifIndex, value = array of VLAN IDs.
These are the VLANs which are members of the egress list for the port. It
is the union of tagged, untagged, and auto ports when using HP-VLAN.
Looks in Q-BRIDGE-MIB first (L<SNMP::Info::Bridge/"TABLE METHODS">) and for
older devices looks in HP-VLAN.
Example:
my $interfaces = $hp->interfaces();
my $vlans = $hp->i_vlan_membership();
foreach my $iid (sort keys %$interfaces) {
my $port = $interfaces->{$iid};
my $vlan = join(',', sort(@{$vlans->{$iid}}));
print "Port: $port VLAN: $vlan\n";
}
=item $hp->bp_index()
Returns reference to hash of bridge port table entries map back to interface identifier (iid)
Returns (B<ifIndex>) for both key and value for 1600, 2424, 4000, and 8000 models
since they seem to have problems with BRIDGE-MIB
=back
=head2 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 de-duplicate if necessary.
=over
=item $hp->hasCDP()
Returns true if the device is running either CDP or LLDP.
=item $hp->c_if()
Returns reference to hash. Key: iid Value: local device port (interfaces)
=item $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.
=item $hp->c_port()
Returns reference to hash. Key: iid Value: remote port (interfaces)
=item $hp->c_id()
Returns reference to hash. Key: iid Value: string value used to identify the
chassis component associated with the remote system.
=item $hp->c_platform()
Returns reference to hash. Key: iid Value: Remote Device Type

=head1 SET METHODS
These are methods that provide SNMP set functionality for overridden methods or
provide a simpler interface to complex set operations. See
L<SNMP::Info/"SETTING DATA VIA SNMP"> for general information on set operations.
=over
=item $hp->set_i_vlan(vlan, ifIndex)
Changes an untagged port VLAN, must be supplied with the numeric VLAN
ID and port ifIndex. This method will modify the port's VLAN membership.
This method should only be used on end station (non-trunk) ports.
Example:
my %if_map = reverse %{$hp->interfaces()};
$hp->set_i_vlan('2', $if_map{'1.1'})
or die "Couldn't change port VLAN. ",$hp->error(1);
=item $hp->set_i_pvid(pvid, ifIndex)
Sets port PVID or default VLAN, must be supplied with the numeric VLAN ID and
port ifIndex. This method only changes the PVID, to modify an access (untagged)
port use set_i_vlan() instead.
Example:
my %if_map = reverse %{$hp->interfaces()};
$hp->set_i_pvid('2', $if_map{'1.1'})
or die "Couldn't change port PVID. ",$hp->error(1);
=item $hp->set_add_i_vlan_tagged(vlan, ifIndex)
Adds the port to the egress list of the VLAN, must be supplied with the numeric
VLAN ID and port ifIndex.
Example:
my %if_map = reverse %{$hp->interfaces()};
$hp->set_add_i_vlan_tagged('2', $if_map{'1.1'})
or die "Couldn't add port to egress list. ",$hp->error(1);
=item $hp->set_remove_i_vlan_tagged(vlan, ifIndex)
Removes the port from the egress list of the VLAN, must be supplied with the
numeric VLAN ID and port ifIndex.
Example:
my %if_map = reverse %{$hp->interfaces()};
$hp->set_remove_i_vlan_tagged('2', $if_map{'1.1'})
or die "Couldn't add port to egress list. ",$hp->error(1);
