Using Command-Line Diagnostics
• Delay—delay interval in system clock-ticks (1/52 second) that must elapse
before the task runs
Follow the steps in the “Entering Diagnostic Commands” section on page 9-20 to
open the CLI and enter the :vxdiag_i command.
:vxdiag_ipstatshow
Use the :vxdiag_ipstatshow command to display IP statistics for the access point.
The IP statistics might look like the following example:
total 5760
badsum 0
tooshort 0
toosmall 0
badhlen 0
badlen 0
infragments 0
fragdropped 0
fragtimeout 0
forward 0
cantforward 0
redirectsent 0
unknownprotocol 0
nobuffers 0
reassembled 0
outfragments 0
noroute 0
These are descriptions of each IP statistic:
• Total—the total number of packets received
• Badsum—number of packets received with bad checksums
• Tooshort—number of packets received that were shorter than the expected
length
• Toosmall—number of packets received that did not have enough data
• Badhlen—number of packets received with IP header length less than the
packet data size
• Badlen—number of packets received with IP length less than the IP header
length
• Infragments—number of packets received that were fragmented
