o outPkts – Number of packets sent by the AP at the RF Interface over the collection interval
o Discards (in/out) – Number of packets that had to be discarded by the AP at the respective
RF Interface Queue during the collection interval
o Discards % (in/out) – Percent of the total packets received / transmitted that had to be
discarded during the collection interval
LUID RF Throughput Stats
This table contains a row that corresponds to each active LUID served by the AP. Note that an LUID
may be assigned 1 or 2 VCs. If the LUID is assigned 2 VCs, then the data in the table is the sum of the
activity for both VCs. This table may be used to determine which LUIDs are experiencing overload so
that corrective action can be taken (i.e. fixing a poor RF link or moving a heavily loaded link to a less
congested AP). Each row contains counters and statistics related to the RF Interface that are updated
once per minute:
Inbound Statistics - Statistics collected at the RF Interface for the Uplink:
o octets – Number of octets (bytes) received by the AP at the RF Interface for this LUID over
the collection interval
o pkts – Number of packets received by the AP at the RF Interface for this LUID over the
collection interval
o Ave Pkt Size – Average size of the packets received by the AP at the RF Interface for this
LUID over the collection interval
o discards – Number of packets received by the AP at the RF Interface for this LUID over the
collection interval that had to be discarded because the RF In Queue was full
o discards % – Percent of the total packets received by the AP at the RF Interface for this
LUID over the collection interval that had to be discarded because the RF In Queue was full
Outbound Statistics - Statistics collected at the RF Interface for the Downlink:
o octets – Number of octets (bytes) transmitted by the AP at the RF Interface for this LUID
over the collection interval
o pkts – Number of packets transmitted by the AP at the RF Interface for this LUID over the
collection interval
o Ave Pkt Size – Average size of the packets transmitted by the AP at the RF Interface for this
LUID over the collection interval
o discards – Number of packets to be transmitted by the Access Point at the RF Interface for
this LUID over the collection interval that had to be discarded because the RF Out Queue was
full
o discards % – Percent of the total packets to be transmitted by the AP at the RF Interface for
this LUID over the collection interval that had to be discarded because the RF Out Queue was
full.
Using the Sessions Tool (AP)
The PMP 450 AP has a tab Sessions under the Tools category which allows operators to drop one or all
selected SM sessions and force an SM re-registration. This operation is useful to force QoS changes for
SMs without losing AP logs or statistics. This operation may take at most 5 minutes to regain all SM
registrations.
