Static Route

Static routes allow the Switch to communicate with management

stations not reachable via the default gateway.

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.

IP Multicast

With IP multicast, the Switch delivers IP packets to a group of hosts on

the network - not everybody. In addition, the Switch can send packets to

Ethernet devices that are not VLAN-aware by untagging (removing the

VLAN tags) IP multicast packets.

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 and

Accounting

The Switch supports authentication 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 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.
