The following tables list the product specifications.
Dynamic ARP Dynamic ARP allows you to filter incoming traffic based on the MAC to
IP address mapping. The switch can be configured to only allow trusted
devices to communicate via its ports.
RMON-Lite Remote Network Monitoring Management (RMON) allows you to gather
information about the switch’s performance, view statistics and create
alarms.
Cable Diagnostics Use this feature to inspect the Ethernet cables connected to the switch
for shorts, open faults or shorts-between-pairs.
Logging The switch allows you to specify what information should be logged and
where it should be stored. It supports internal logging as well as external
logging via a syslog server.
