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 de-duplicate if necessary.
