ARP snooping active on interfaces: lan wan dmz
ARP on wan: gw-world requesting wan_ip
ARP on lan: 192.168.123.5 requesting lan_ip
Buffers
This command can be useful for troubleshooting. For example, if an unexpectedly large number of
packets begin queuing or when traffic does not seem to be flowing for an unknown reason. By
analyzing the contents of the buffers, it is possible to determine whether such traffic is making it to
the DFL-160 at all.
Syntax: buffers
Brings up a list of most recently freed buffers.
Example:
DFL-160:/> buff
