Interpreting RF Control Block statistics

The Statistics > Radio page is applicable for all module (AP/SM/BHM/BHS). The Radio page of the

Statistics page displays the following fields.

Table 211 Radio (Statistics) page attributes – RF Control Block

Attribute

Meaning

inoctets Count

This field displays how many octets were received on the interface,

including those that deliver framing information.

inucastpkts Count

This field displays how many inbound subnetwork-unicast packets were

delivered to a higher-layer protocol.

Innucastpkts Count

This field displays how many inbound non-unicast (subnetwork-

broadcast or subnetwork-multicast) packets were delivered to a higher-

layer protocol.

indiscards Count

This field displays how many inbound packets were discarded without

errors that would have prevented their delivery to a higher-layer

protocol. This stat is pegged whenever corrupt data is received by

software or whenever the RF Software Bridge queue is full.

Corrupt data is a very unusual event because all packets are CRC

checked by hardware before being passed into software.

The likely case for indiscards is if the RF bridge queue is full. If this is the

case the radio is most likely PPS limited due to excessive small packet

traffic or a problem at the Ethernet interface. If there is a problem at the

Ethernet interface there is likely to be discards at the Ethernet as well.

inerrors Count

This field displays how many inbound packets contained errors that

prevented their delivery to a higher-layer protocol.

inunknownprotos

Count

This field displays how many inbound packets were discarded because

of an unknown or unsupported protocol.
