Functional Description
Jumbo Frame
With Jumbo Frame supported, it is allowed for the switch to transport
identical data in fewer frames. Hence helps to ensure fewer overheads,
shorten processing time, and reduce interrupts.
Note: To enable Jumbo Frame, Flow Control should be enabled in advance.
Flow Control and Back Pressure
Flow control and Back Pressure both contributes for lower and higher speed
devices to communicate to each other hence ensures the correctness of
data transmitting. The 802.3x flow control and Back Pressure mechanisms
work respectively for full and half duplex modes. Flow control can be
enabled or disabled on a per-port basis.
Mirror
The Mirror function provides network administrator to monitor the traffic. By
forwarding a copy of the packets that transferred by the source port, the
monitoring port received all the packets and hence is able to monitor the
traffic of this specific port.
VLAN
With VLAN supported, the network can be segmented in groups to reduce
the collisions from widely broadcasting. The device supports 802.1Q tag
based VLAN, which add tags to the header of the packet to classify their
VLANs.
Trunk (Aggregation)
The Trunk functionality integrates several ports to enlarge the bandwidth
that helps to boost the backbone connectivity.
Quality of Service (QoS)
The QoS service classifies packets into different precedence. The packets
are transmitted and received by their classified priorities. This mechanism
helps high bandwidth demanded applications such as VoIP to get an
unobstructed connection.
SNMP
This device is SNMP(Simple Network Management Protocol)-management
supported. This allows this product to be monitored or inspected by a SNMP
management station.
