|
|
|
|
Abstraction subclass for HP network devices which Foundry Networks was the

Original Equipment Manufacturer (OEM) such as the HP ProCurve 9300 series.
|
|
|
|
For speed or debugging purposes you can call the subclass directly, but not
|
|
after determining a more specific class using the method above.

=head2 Topology information
|
|
|
|
Based upon the software version devices may support Foundry Discovery
|
|
Protocol (FDP) and Link Layer Discovery Protocol (LLDP). 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.
|
|
|
|
=over
|
|
|
|
=item $hp9300->hasCDP()
|
|
|
|
Returns true if the device is running either FDP or LLDP.
|
|
|
|
=item $hp9300->c_if()
|
|
|
|
Returns reference to hash. Key: iid Value: local device port (interfaces)
|
|
|
|
=item $hp9300->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-FDP/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 $hp9300->c_port()
|
|
|
|
Returns reference to hash. Key: iid Value: remote port (interfaces)
|
|
|
|
=item $hp9300->c_id()
|
|
|
|
Returns reference to hash. Key: iid Value: string value used to identify the
|
|
chassis component associated with the remote system.
|
|
|
|
=item $hp9300->c_platform()
|
|
|

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