Classifier and Policy You can create a policy to define actions to be performed on a traffic flow grouped by a
classifier according to specific criteria such as the IP address, port number or protocol
type, etc.
Queuing Queuing is used to help solve performance degradation when there is network
congestion. Three scheduling services are supported: Strict Priority Queuing (SPQ)
and Weighted Round Robin (WRR). This allows the switch to maintain separate
queues for packets from each individual source or flow and prevent a source from
monopolizing the bandwidth.
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.
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.
Configure Clone The switch allows you to copy multiple attributes of one port and apply them to other
ports on the switch.
