Class-of-Service (CoS) Support
The TigerSwitch 10/100 provides two transmit queues on each
port, with a weighted fair queing scheme. This function can be
used to provide independent priorities for various types of data
such as real-time video or voice, and best-effort data.
Priority assignment to a packet in the TigerSwitch 10/100 can be
accomplished in any of the following ways:
•
Priority can be explicitly assigned by end stations which have
applications that require a higher priority than best-effort. This
switch utilizes the IEEE 802.1p and 802.1Q tag structure to
decide priority assignments for the received packets.
•
A port may be manually configured as high priority. In this
case, when any other port receives traffic from a high-priority
port, that traffic is automatically placed in the high-priority
output queue.
Port Trunks
Ports can be combined into an aggregate link to increase the
bandwidth of a network connection or ensure fault recovery. You
can group ports into trunks that consist of two, three or four ports,
creating an aggregate bandwidth up to 4 Gbps when grouping
multiple Gigabit ports. Besides balancing the load across each port
in the trunk, the additional ports provide redundancy by taking
over the load if another port in the trunk should fail.
When using port trunks, remember that:
•
Before removing a port trunk via the configuration menu, you
must disable all the ports in the trunk or remove all the network
cables. Otherwise, a loop may be created.
