DESCRIPTION
Bandwidth control means defining a maximum allowable bandwidth for
incoming and/or out-going traffic flows on a port.
Broadcast storm control limits the number of broadcast, multicast and
destination lookup failure (DLF) packets the Switch receives per second
on the ports.
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 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 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!
