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!
