Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows
Description
The number of multicast packets that were received successfully.
The number of broadcast packets that were received successfully.
The number of unicast packets that were received successfully.
The number of bytes of data that were received successfully.
The number of beacon packets that were received successfully.
The number of all packets that were received successfully.
The number of duplicate packets that were received successfully.
The number of packets received when no receive buffers were
available. These errors usually occur when the host does not read
the received packets from the client adapter fast enough.
The number of times the client adapter started to receive an
802.11 physical layer convergence protocol (PLCP) header but
the rest of the packet was ignored due to a cyclic redundancy
check (CRC) error in the header.
CRC errors can be attributed to packet collisions caused
Note
by a dense population of client adapters, overlapping
access point coverage on a channel, high multipath
conditions due to bounced signals, or the presence of
other 2.4-GHz signals from devices such as microwave
ovens, wireless handset phones, etc.
The number of times an 802.11 PLCP header was received with a
valid CRC but the rest of the packet was ignored due to an
unknown value in the header.
The number of times an 802.11 PLCP header was received but the
rest of the packet was ignored due to an illegal header length.
The number of packets that had a valid 802.11 PLCP header but
contained a CRC error in the data portion of the packet.
Note CRC errors can be attributed to packet collisions caused
by a dense population of client adapters, overlapping
access point coverage on a channel, high multipath
conditions due to bounced signals, or the presence of
other 2.4-GHz signals from devices such as microwave
ovens, wireless handset phones, etc.
The number of fragments that were discarded because the entire
packet was not received successfully.
The number of times the client adapter tried to associate to an
access point but was unable to because the adapter's SSID was not
the same as the access point's.
