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.
RIP RIP (Routing Information Protocol) allows a routing device to exchange
routing information with other routers.
RSTP (Rapid Spanning
Tree Protocol) / MRSTP
(Multiple RSTP)
RSTP detects and breaks network loops and provides backup links
between switches, bridges or routers. It allows a switch to interact with
other RSTP-compliant switches in your network to ensure that only one
path exists between any two stations on the network. MRSTP allows you
to configure multiple RSTP configurations and assign ports to each tree.
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. For redundancy,
multiple RADIUS servers can be configured.
Device Management Use the web configurator to easily configure the rich range of features on
the Switch.
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.
