TATISTICS

Use the LLDP Port Statistics page to display statistics on LLDP global

counters and control frames.

ARAMETERS

These parameters are displayed on the LLDP Port Statistics page:

Global Counters

◆

Neighbor entries were last changed at

- The time the LLDP

neighbor entry list was last updated. It also shows the time elapsed

since last change was detected.

◆

Total Neighbors Entries Added

- Shows the number of new entries

added since the switch was rebooted, and for which the remote TTL has

not yet expired.

◆

Total Neighbors Entries Deleted

- The number of LLDP neighbors

which have been removed from the LLDP remote systems MIB for any

reason.

◆

Total Neighbors Entries Dropped

- The number of times which the

remote database on this switch dropped an LLDPDU because the entry

table was full.

◆

Total Neighbors Entries Aged Out

- The number of times that a

neighbor’s information has been deleted from the LLDP remote systems

MIB because the remote TTL timer has expired.

LLDP Statistics

◆

Local Port

- Port Identifier.

◆

Tx Frames

- Number of LLDP PDUs transmitted.

◆

Rx Frames

- Number of LLDP PDUs received.

◆

Rx Errors

- The number of received LLDP frames containing some kind

of error.

◆

Frames Discarded

- Number of frames discarded because they did not

conform to the general validation rules as well as any specific usage

rules defined for the particular Type Length Value (TLV).

◆

TLVs Discarded

- Each LLDP frame can contain multiple pieces of

information, known as TLVs. If a TLV is malformed, it is counted and

discarded.

◆

TLVs Unrecognized

- The number of well-formed TLVs, but with an

unknown type value.

◆

Org. Discarded

- The number of organizational TLVs discarded.
