LLDP TX Statistics No. of Length Error - The number of LLDPDU Length
Errors recorded for this port and destination MAC address. If the set of
TLVs that is selected in the LLDP local system MIB by network
management would result in an LLDPDU that violates LLDPDU length
restrictions, then the No. of Length Error statistic is incremented by 1, and
an LLDPDU is sent containing the mandatory TLVs plus as many of the
optional TLVs in the set as will fit in the remaining LLDPDU length.
19.2.7.3 Displaying LLDP Received Frames Statistics (CLI)
To display statistics about LLDP frames received by the unit, enter the
following command in root view:
root> ethernet lldp statistics-port-rx-show
The following information is displayed:
RX Destination Port - The index value used to identify the port in LLDP
transmissions.
RX DA Index - The index value used to identify the destination MAC
address associated with this entry.
RX Total Discarded - The number of LLDP frames received by the LLDP
agent on this port, and then discarded for any reason. This counter can
provide an indication that LLDP header formatting problems may exist
with the local LLDP agent in the sending system or that LLDPDU validation
problems may exist with the local LLDP agent in the receiving system.
RX Invalid Frames - The number of invalid LLDP frames received by the
LLDP agent on this port while the agent is enabled.
RX Valid Frames - The number of valid LLDP frames received by the LLDP
agent on this port.
RX Discarded TLVs - The number of LLDP TLVs discarded for any reason
by the LLDP agent on this port.
RX Unrecognized TLVs - The number of LLDP TLVs received on the given
port that are not recognized by LLDP agent.
RX Ageouts - The number of age-outs that occurred on the port. An age-
out is the number of times the complete set of information advertised by
the remote system has been deleted from the unit's database because the
information timeliness interval has expired. This counter is similar to
the
LLDP No. of Ageouts
counter, except that it is per port rather than for
the entire unit. This counter is set to zero during agent initialization. This
counter is incremented only once when the complete set of information is
invalidated (aged out) from all related tables on a particular port. Partial
ageing is not allowed.
