6.6.1 Port Trunking
In telecommunications, trunking is a method for a system to provide network access to many clients by
sharing a set of lines or frequencies instead of providing them individually. This is analogous to the
structure of a tree with one trunk and many branches. Trunking, is set by the configuration software, the
two or more physical ports get together into a logical path to increase the bandwidth between the switch
and the network node. Trunking is a packaging technology, it is a peer to peer link, both ends of the link
are switches, it can be a switch and a router, and also can be a host, switch or router.
Based on port
trunking function that allows between two or more ports between switches, switches and routers, hosts
the switch or router connected in parallel to provide for the simultaneous transmission of higher
bandwidth and greater throughput, significantly entire network capacity. Trunking is more economical to
1.
Port priority is the highest level, don't need to check other QoS attributes is discharged into the highest priority
queue if you set the port priority as 1.
2. DSCP priority comes second, unless we do not set DSCP, therefore will check 802.1p priority, otherwise it will
line up according to the DSCP settings.
3.
As above, the three priority can be used alone, can also be used at the same time, queuing according to the
above rules.
