- arpsnoop all
Snoop all interfaces.

Buffers
This command can be useful in troubleshooting; e.g. if an unexpectedly
large number of packets begin queuing in the firewall or when traffic does
not seem to be flowing for some inexplicable reason. By analyzing the
contents of the buffers, it is possible to determine whether such traffic is
making it to the firewall at all.
Syntax:
-- buffers
Brings up a list of most recently freed buffers.
