Iar TRUNK-ul il faci intre doua switch-uri cu management. But, if you want to simulate the purpose of VLAN when you do not have a switch tagged with 802. Cisco used to support its own proprietary trunking protocol for VLAN tagging – ISL, or InterSwitch Link Protocol. In this way, VLANs can keep network applications separate despite being connected to the same physical network, and without requiring multiple sets of cabling and networking devices to be deployed. Comandos:ROUTER 0 enableconf t interface fastethernet 0/0no shutexit interface fastethernet 0/0. Without the switchport mode access command, if the neighbouring port is a trunk port, the port will be configured as a trunk. 300 iface eth1. To do this first we need to understand the different types of networks. Unfortunately, for a minority of Ethernet and FastEthernet cards there is no support for trunking 802. VTP will let you create VLANs on one switch and all the other switches. A non-trunk port-- also called access port -- carries traffic for a single VLAN, but a trunk port carries traffic for multiple VLANs simultaneously. For example, edge switch A may receive a packet through port #9, apply tag #1, and then push that packet to all ports in VLAN #1 and to core switch B through a VLAN trunk. That’s a time consuming task so there is something to help us called VTP (VLAN Trunking Protocol).
