Note
1.
If the default priority is High, then other QoS property will not be checked and put into High priority queuing
2.
DSCP is lower than default priority, if there is no settings about DSCP, 802.1P will be checked, or the queuing will
be based on DSCP settings.
3.
The above 3 kinds of priority can be used both independently and together.
Redundancy
Port Trunking
Main features of TRUNK is to bind several physical ports (general number is 2-4) to make a logical channel.
After binding several physical links, bandwidth of entire network improves a lot so that data can be
transmitted through several physical links, which also make many redundant links. When one or more links
are cut off by failure or other reason, the rest of them can continue to work well.
