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
earlier 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.
CPU Protection You can limit the rate of protocol control packets (such as ARP,
BPDU and/or IGMP) to be delivered to the CPU on a port.
Error Disable You can set the Switch to take an action (such as to shut down
a port or stop sending packets) on a port when the Switch
detects a pre-configured error. You can also configure the
Switch to automatically undo the action after the error is gone.
Private VLAN You can set the Switch to prevent communications between
ports in a VLAN to do port isolation within a VLAN.
Policy Routing Policy routing lets you override the default routing behavior and
alter the packet forwarding based on the pre-defined policy.
ARP Learning You can configure the Switch to update the ARP table with with
an ARP reply or a gratuitous ARP request and/or an APR
request.
Load Sharing Load sharing allows the Switch to forward packets destined to
the same device through different routing paths of equal path
cost.
