Sonicwalls devices are firewalls, not switches. Generally port mirroring is
done as a layer 2 operation in hardware. Firewalls generally don't have
hardware layer2 switching between ports, and would have to do the mirror in
software, thus this feature is not common in firewall devices.

AFAIK, none of the Cisco PIX, Cisco IOS, netscreen firewall, sonicwall or
checkpoint firewall products support port mirroring.

Look for a mangaged ethernet switch, that's where you'll usually find
mirroring capabilities.
