OSPF OSPF (Open Shortest Path First) is a link-state protocol
designed to distribute routing information within an
autonomous system (AS). An autonomous system is a
collection of networks using a common routing protocol to
exchange routing information. OSPF is best suited for large
networks.
DVMRP DVMRP (Distance Vector Multicast Routing Protocol) is a
protocol used for routing multicast data within an autonomous
system (AS). DVMRP provides multicast forwarding capability
to a layer 3 switch that runs both the IPv4 protocol (with IP
Multicast support) and the IGMP protocol.
VRRP Virtual Router Redundancy Protocol (VRRP), defined in RFC
2338, allows you to create redundant backup gateways to
ensure that the default gateway of a host is always available.
STP (Spanning Tree
Protocol) / RSTP (Rapid
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.
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 DHCP and 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 and
Accounting The Switch supports authentication 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!
