STP (Spanning Tree
Protocol) / RSTP (Rapid
STP)
(R)STP detects and breaks network loops and provides backup
links between switches, bridges or routers. It allows a Switch to
interact with other (R)STP-compliant switches in your network
to ensure that only one path exists between any two stations
on the network.
Defence Engine Use the defence engine feature to protect the CPU from
overwhelming by flooding traffic.
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.
Link Aggregation Link aggregation (trunking) is the grouping of physical ports
into one logical higher-capacity link. You may want to trunk
ports if for example, it is cheaper to use multiple lower-speed
links than to under-utilize a high-speed, but more costly,
single-port link.
Port Authentication and
Security
For security, the Switch allows authentication using IEEE
802.1x with an external RADIUS server and port security that
allows only packets with dynamically learned MAC addresses
and/or configured static MAC addresses to pass through a port
on the Switch.
Authentication and
Authorization
The Switch supports authentication and authorization services
via RADIUS AAA servers.
Device Management Use the web configurator or commands to easily configure the
rich range of features on the Switch.
Syslog The Switch can generate syslog messages and send it to a
syslog server.
Firmware Upgrade Download new firmware (when available) from the ZyXEL web
site and use the web configurator and TFTP tool to put it on the
Switch.
Note: Only upload firmware for your specific model!
Configuration Backup &
Restoration
Make a copy of the Switch’s configuration and put it back on
the Switch later if you decide you want to revert back to an
earlier configuration.
