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.
Loop Guard Use the loop guard feature to protect against network loops on
the edge of your network.
IP Source Guard Use IP source guard to filter unauthorized DHCP and ARP
packets in your network.
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,
Authorization and
Accounting The Switch supports authentication, authorization and
accounting services via RADIUS and AAA servers.
Device Management Use the web configurator or commands to easily configure the
rich range of features on the Switch.
Port Cloning Use the port cloning feature to copy the settings you configure
on one port to another port or ports.
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, CLI or an FTP/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
earl
i er configuration.
Cluster Management Cluster management (also known as iStacking) allows you to
manage switches through one switch, called the cluster
manager. The switches must be directly connected and be in
the same VLAN group so as to be able to communicate with
one another.
sFlow sFlow allows the Switch to monitor traffic in a network by
getting sample data and packet statistics from traffic, and send
information to an sFlow collector for analysis.
PPPoE IA With the PPPoE Intermediate Agent enabled, the Switch can
give a PPPoE termination server additional subscriber
information that the server can use to identify and authenticate
a PPPoE client.
