system through CONSOLE interface.
LED Indicator
The LEDs indicate the port status correctly including transmission rate, link status and system status.
VLAN
The network can be divided into several VLANs according to ports, through which the users in one VLAN
can communicate each other. The VLAN of KIEN6000T conforms to IEEE802.1Q and can realize the
communication within one VLAN of different switches. KIEN6000T supports up to sixteen VLANs based
on IEEE802.1Q.
802.1p Prioritization
KIEN6000T conforms to 802.1p, which is used the most widely in LAN environment. The end-users of
KIEN6000T can make use of this function to configure the port-based prioritization when 802.1p is not
supported at user’s end and different priority is necessary for different ports’ services. Only the data
package without Prioritization in the Packet in the ports can be affected by this function. Each port of
KIEN6000T supports 2 levels (high, low) prioritization.
Layer-2 Switching
Switches work in two ways: Cut-Through and Store-and-Forward. In Cut-Through, a data packet is
immediately relayed further after detecting the target address; in Store-and-Forward, a data packet is
first read-in completely and checked for errors before the switch relays the same. KIEN6000T employs
Store-and-Forward that is a switching mode widely used.
Broadcast Storm Control
Broadcast storm is the ceaseless transfer of broadcast frame or multicast frame in bridge, which is
caused by loop and will waste much bandwidth. The purpose of broadcast storm control is to optimize
the performance of switch network. KIEN6000T supports the broadcast storm based on percentage.
With the control percentage, the broadcast flow of KIEN6000T will be monitored and controlled
effectively. The switch will filter out the over flow and ensure the flow percentage is normal once the
bandwidth of broadcast flow exceed the limit.
Alarming
KIEN6000T offers the alarming functions for power, port link and network. Through management
software, all the alarming functions can be configured functionally. The alarming information is shown
on management interface.
Setting for Working Mode of Port
KIEN6000T is able to set the w orking mode of all ports through management: full/half duplex,
