Trunk Overview
"trunk" is generally translated in network parlance: "trunk, trunk, long-distance lines," but generally do not have Italian translation, direct English. Routing / switching network, trunk commonly referred to as a "relay (pass-through)." In applications in voice-grade line, generally refers Trunk circuit connection or channel between the "backbone network telephone trunk", i.e., two or exchange switch for switching it between two devices, and a signaling terminal data transmission link device.
Trunk Configuration Lab
Step 1: Pull into the operating area of GNS3 two switches and four PC.
Step two: two switches then performed in the same hardware configuration.
Step Three: Next we need to interface and IP address of the PC and switch to plan.
Step four: to configure the device against the plan. Here we first entered the global schema canceled routing function of the switch, then we configure the switch sw1 of two interfaces, interface f1 / 0 configured vlan10, the interface f1 / 1 configured as vlan20, and finally remember to check the configuration.
Next, the switch sw1 sw2 carried out as the same configurations.
Here we first sw1 interface f1 / 2 and f1 / 3 were trunk configuration, the configuration is complete remember to check the configuration.
Sw1 and sw2 for the same operating configuration.
Here are four of the IP address of the PC to set up.
The following four between PC, stitching, experimental results show that the same can be between only the same VLAN. The trunk can also be described by all data vlan.
Then we will strapping together two trunk link, the first two switches tied f1 / 2 and f1 /. 3 two interfaces.
After then disconnected while the two switches f1 / 2 interface.
Then during the test interconnection between two identical vlan, results show a case where a two trunk link is disconnected for some reason does not affect the normal communication between devices.
The experiment proved that we can be across multiple vlan switch only communicate via a link. It also shows the interface including Ethernet channel if there is a trunk accidentally disconnected and will not affect the normal communication between our two facilities in the trunk.
