DESCRIPTION
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!
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 earlier configuration.
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.
Static MAC forwarding lets you configure forwarding rules based on the
MAC addresses of devices on your network.
Multiple Spanning Tree Protocol (IEEE 802.1s) is backwards-compatible
with STP/RSTP and addresses the limitations of existing spanning tree
protocols (STP and RSTP).
SNMP v3 enhances security for SNMP management. SNMP managers
can be required to authenticate with agents before conducting SNMP
management sessions.
You can specify the types of SNMP traps that should be sent to each
SNMP manager.
Daylight saving is a period from late spring to early fall when many
countries set their clocks ahead of normal local time by one hour to give
more daytime light in the evening.
The Switch can forward DHCP requests to DHCP servers on your
network.
