Displaying WAN IP interface information
The following commands provide information about WAN IP interfaces.
Displaying packets on WAN IP interfaces
The
wandisplay
command displays all packets received from, or sent to any of the IP
WAN interfaces. Because
wandisplay
output shows what the Stinger unit is receiving
from and sending to a remote device, the information can be very helpful in resolving
PPP negotiation problems. The syntax of the command is as follows:
wandisplay
number-of-octets-to-display
If you enter the command while traffic through the Stinger unit is heavy, the
resulting amount of output can make your search for information tedious. The screen
might even display the message
----- data lost -----
, which means that not all the
output can be displayed on the screen.
Depending on the types of information you need to gather, you might prefer to use
the
wandisplay
command during a period of low throughput, or to use
wandsess
,
wanopen
, or
wannext
to focus the display.
The following is an example of
wandisplay
command output. Note that the bytes are
displayed in hexadecimal format.
