B: Show 802.11 Errors

B.1 Introduction

When you enter the Show 80211 command without any other parameters, the resulting screen includes a field for errors. The “Errors:” field displays two eight-digit numbers, separated by a comma. These numbers are a 64-bit wide bitfield of error bits, each one indicating whether or not the given error has occurred at least once.

For example, suppose you're using an MSS-Via with a ZoomAir card in Infrastructure mode. After having been running for a long time, your Access Point loses power in the middle of sending a fragmented packet to the MSS. If you entered the Show 80211 command, you might see a screen resembling the following:
