Port Mirroring Port mirroring allows you to copy traffic going from one or all ports to
another or all ports in order that you can examine the traffic from the
mirror port (the port you copy the traffic to) without interference.
Static Route Static routes tell the Switch how to forward IP traffic when you configure
the TCP/IP parameters manually.
Multicast VLAN Registration
(MVR)
Multicast VLAN Registration (MVR) is designed for applications (such as
Media-on-Demand (MoD)) using multicast traffic across a network. MVR
allows one single multicast VLAN to be shared among different
subscriber VLANs on the network.
This improves bandwidth utilization by reducing multicast traffic in the
subscriber VLANs and simplifies multicast group management.
STP (Spanning Tree
Protocol) / RSTP (Rapid
STP) / MSTP (Multiple 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. The Switch also
allows you to set up multiple STP configurations (or trees). Ports can
then be assigned to the trees.
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 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 TACACS+ 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 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.
