DESCRIPTION
Static routes allow the Switch to communicate with
management stations not reachable via the default gateway.
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.
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.
(M)(R)STP detects and breaks network loops and provides
backup links between switches, bridges or routers. It allows a
Switch to interact with other (M)(R)STP-compliant switches in
your network to ensure that only one path exists between any
two stations on the network.
Use the loop guard feature to protect against network loops on
the edge of your network.
Use IP source guard to filter unauthorized DHCP and ARP
packets in your network.
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.
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.
The Switch supports authentication, authorization and
accounting services via RADIUS and TACACS+ AAA servers.
Use the web configurator or commands to easily configure the
rich range of features on the Switch.
Use the port cloning feature to copy the settings you configure
on one port to another port or ports.
The Switch can generate syslog messages and send it to a
syslog server.
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!
