Chapter 3: Operation System statisticsPage 3-47Interpreting RF Control Block statisticsThe Statistics > Radio page is applicable for all module (AP/SM/BHM/BHS). The Radio page of theStatistics page displays the following fields.Table 133 Radio (Statistics) page attributes – RF Control BlockAttribute Meaninginoctets Count This field displays how many octets were received on the interface, includingthose that deliver framing information.inucastpkts Count This field displays how many inbound subnetwork-unicast packets weredelivered to a higher-layer protocol.Innucastpkts Count This field displays how many inbound non-unicast (subnetwork-broadcast orsubnetwork-multicast) packets were delivered to a higher-layer protocol.indiscards Count This field displays how many inbound packets were discarded without errorsthat would have prevented their delivery to a higher-layer protocol. This statis pegged whenever corrupt data is received by software or whenever theRF Software Bridge queue is full.Corrupt data is a very unusual event because all packets are CRC checkedby hardware before being passed into software.The likely case for indiscards is if the RF bridge queue is full. If this is thecase the radio is most likely PPS limited due to excessive small packet trafficor a problem at the Ethernet interface. If there is a problem at the Ethernetinterface there is likely to be discards at the Ethernet as well.inerrors Count This field displays how many inbound packets contained errors thatprevented their delivery to a higher-layer protocol.inunknownprotosCountThis field displays how many inbound packets were discarded because of anunknown or unsupported protocol.outoctets Count This field displays how many octets were transmitted out of the interface,including those that deliver framing information.
