FEATURE

DESCRIPTION

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.
