Appendix A: WLAN Application Gateway 2246
• Stats Time Period – the length of time the statistics have been
accumulating in the Pkts and Bytes columns. This is either the system
uptime, or the time that has elapsed since a user pressed C=Clear while
viewing this display.
• User Time Period – the length of time (in seconds) that statistics
accumulate in the Userpkts column before resetting to zero. When
troubleshooting a problem, use this setting to isolate statistics for a given
time period (for example, one hour). This is the only field in this screen
that can be changed by the user.
The rest of the display is a table of Ethernet statistics. The Pkts and User Pkts
columns list the count of Ethernet packets received or transmitted. The Bytes
column is the count of bytes received or transmitted during the amount of
time indicated by the Stats Time Period.
• RX – number of packets and bytes received addressed to the WLAN
Application Gateway 2246.
• RX Broadcast – the number of broadcast packets and bytes received.
• RX Multicast – the number of packets and bytes received with the
multicast address. (A "multicast" message is sent to more than one
destination on the network.)
• RX Not For Us – the number of multicast packets and bytes received
that were not for the WLAN Application Gateway 2246.
• TX – the total number of packets and bytes transmitted.
• Interrupts – the number of times the Ethernet controller signals the
microprocessor that it has received or sent a packet.
• Collisions – the number of times the Ethernet controller attempts to send
a packet, but another device on the network transmitted at the same time,
corrupting the transmission.
• Collision Drops – the number of packets the Ethernet controller
discards, because there were over sixteen collisions. After sixteen
collisions, the Ethernet controller hardware discards the current packet
and attempts to send the next packet in its buffer.
• CRC Errors – the number of packets discarded by the Ethernet
controller, because of a Cyclic Redundancy Check (CRC) error.
