TRUNK port aggregation is the meaning of the settings through the configuration software will be two or more physical ports together into a logical path in order to increase the switch and the network bandwidth between nodes, the port will belong to these bandwidth combined to give the port a few times in the exclusive independent high-bandwidth ports. Trunk is a packaging technology, it is a point to point link, both ends of the link to all switches, it can be switches and routers, and switches can also be a host or router. Port-based aggregation (Trunk) feature allows the switch and switches, switches and routers, between the host and the switch or router ports through the parallel connection of two or more simultaneous transmission in order to provide higher bandwidth, more throughput, to provide the substantial network capacity.

basic meaning tree is four meters thick. This tree is four meters thick. 2. (Travel) large box; car the trunk Let me put your baggage in the trunk. I have to put your luggage in the rear of the car's trunk. 3. Trunk; insects and other long-mouth 4. Torso, the body The athlete has a powerful trunk. The athlete body powerful. 5. (Railways, highways, etc.) Route 6. The great vessels, neural stem 7. Men's shorts; men's swimming trunks (especially ######y or fun classes) [P] 8. Tanks a mine washing tr vt. 1. tank washing (ore) The word on different occasions and also have different explanations: 1, the network's hierarchical structure and the rational distribution of broadband, TRUNK be interpreted as TRUNK to bundle multiple physical ports to use as a logical port, multiple ports can be added together with broadband. TRUNK TRUNK technology allows multiple links within each other's backup feature, that is, when a link fails, does not affect the work of other links, but also for traffic between multiple links balanced, just as we are familiar with MODEM printer pool and pool the same. 2,
air force one low, in the voice-grade telecommunications network lines, Trunk means the the necessary signaling and terminal equipment. 3, but the most common areas of routing and switching,
air force one high, VLAN port aggregation also some calling TRUNK, but most call TRUNKING, such as CISCO company. The so-called TRUNKING is used to switch between different connections across multiple switches in order to ensure the establishment of a member of the same VLAN can communicate with each other. Interconnection between the switch which port to use as TRUNK ports. Cascade of switches in general different, TRUNKING is based on the OSI Data Link Layer Layer (DataLinkLayer) RUNKING technology, if you were in two by a number on the switch VLAN (VLAN is also based on Layer2), then at VLAN10 and two switches on the members of the respective VLAN20 If you want to exchange, you need to switch on the A port is set to fetch a VLAN10 and switch B on the set for a port VLAN10 cascade connection. VLAN20 well. So if the switch on the designated VLAN 10, respectively, need to be cascaded with 10 lines, port efficiency is too low. When the switch supports TRUNKING when things simple, only two switches there is a cascade line, and the corresponding port is set to Trunk, this route can carry all the VLAN information on the switch. In this case, even if the switch is also set up hundreds of all VLAN port with only one solved. If it is different from the same station id of the vlan on the switch to communicate with each other, then the trunk port by sharing can be achieved, if it is different from the same platform id of vlan / vlan id, different sets of different between them to communicate with each other, need to routing through a third party to achieve; vlan division has two caveats: First, by several different vlan group has a different vlan id number; assigned to the vlan group inside the switch ports have port id. such as port 1,2,3,4 divided into vlan10, 5,6,7,8 divided into vlan20, I can port the port id 1,3,4 set to 10, while the 2-port port id is set to 20; the 5,6,7 port port id is set to 20, while the 8-port port id is set to 10. In this case, vlan10 of 1,3,
nike air force 1 high,4,
air force 1 high, 8-port to port and vlan20 communicate with each other; and vlan10 The 2-port to port and vlan20 communicate with each other in 5,6,7; Although the vlan id different,
air force one shoes, but the port id same, will be able to communicate, the same the same vlan id,
nike air force one low, port id but not between different port each visit, such as vlan10 the 2-port can not, and 1,3,4-port communication. Atlas Atlas entry for more extended reading: 1
