Attribute Meaning
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 will be 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.
outoctets Count This field displays how many octets were transmitted out of the
interface, including those that deliver framing information.
outucastpkts Count This field displays how many packets for which the higher-level
protocols requested transmission to a subnetwork-unicast address.
The number includes those that were discarded or not sent.
outnucastpkts Count This field displays how many packets for which the higher-level
protocols requested transmission to a non-unicast (subnetwork-
broadcast or subnetwork-multicast) address. The number includes
those that were discarded or not sent.
outdiscards Count This field displays how many outbound packets were discarded
without errors that would have prevented their transmission.
The
link can be at capacity due to bandwidth being exceeded, poor RF
links to the SMs, or sudden interference.
outerrrors Count This field displays how many outbound packets contained errors
that prevented their transmission.
Interpreting Data in the VLAN Tab (All)
The VLAN tab in the Statistics web page provides a list of the most recent packets that were
filtered because of VLAN membership violations.
