Priority assignment to a packet in the TigerStack 100 can be accomplished
in any of the following ways:
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 8 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.

Otherwise, a loop may be created.
•
To disable a single link within a port trunk, you should first remove the
network cable, and then disable both ends of the link via the
configuration menu. This allows the traffic passing across that link to
be automatically distributed to the other links in the trunk, without
losing any significant amount of traffic.
