In this lab, you will configure trunk-based inter-VLAN routing and verify connectivity to hosts on different VLANs as well as with a loopback on the router. Some newer switches only support 802.1Q and in that case this command will be unavailable. In this way, we will be passing a trunk of VLANs. You must enable the Trunk feature on each device port to transmit information of different VLANs between switches. On Catalyst switches it is accomplished by the creation of Layer 3 interfaces (switch virtual interfac… Remember earlier in this article I said that VLAN can span anywhere in network, that is happen due to trunk link connection. And it is that no matter […], The Asian manufacturer’s family of activity bracelets has become one of the great references when it comes to buying a smartband. Configure Trunking Ports on Switch With the command “ switch port mode trunk ” you can configure trunking on the FastEthernet 0/1 port of the SW1. • Access link: An access link is a link that is part of only one VLAN, and normally access links are for end devices.Any device attached to an access link is unaware of a VLAN membership. The information found within the frame is modified so that the switches involved can identify both the source and destination VLANs. I have recently taken over responsibility of the management of the switches in my apartment complex. There are two kinds of trunking encapsulations on Ethernet interfaces: - ISL- Inter switch link - 802.1Q is standard encapsulation. Create VLANs 10 and 20 in the switch database Layer3-Switch# configure terminal Layer3-Switch(config)# vlan 10 I want the cisco router to perform inter-vlan routing. For Brocade switches on which the Inter-Switch Links (ISL) are configured using FC ports, you must configure the switch ports on each switch fabric that connect the ISL. Open a console connection to Switch 1 and enter the following IOS commands from global configuration mode to configure VLAN Trunking Protocol (VTP) in Switch 1. To verify the creation of your VLAN you can use the following command: Or you can opt for the abbreviated command: sh vlaneval(ez_write_tag([[250,250],'itigic_com-leader-1','ezslot_20',120,'0','0'])); Expect to see the following on the CLI of each switch: 10 ejemplos active Fa0/11002 fddi-default active1003 token-ring-default active1004 fddinet-default active1005 trnet-default active. Hello, we are trying to get vlan propagation working by using 1 interface on the Cisco and enable trunking(801.1q) on it, and the same on the Dell switch. VTP Pruning. Switch# conf t Switch (config)# interface gigabitethernet 0/1 Switch (config-if)# switchport mode trunk Switch (config-if)# end Switch# wr Before you create the trunk link on the switches, make sure both have a native VLAN installed on them. In addition, we must bear in mind that Cisco has a tool such as Cisco Packet Tracer to perform configuration tests with a simulator. Finally, we only have to assign the IP addresses to each computer and you only need to ping to verify that both computers can communicate correctly. Note: The ports that are displayed in the output are only access ports. There are two types of VLAN connection links and they are Access link and Trunk link.. Rene Ports 3 through 18 are blocking Gigabit ports on the WS-X4418-GB module. So, you have to use “switchport trunk allowed vlan” and specify the VLAN number as shown below. In the first line we can see our VLAN number 10 with an example name. Cisco Layer 3 Switch! Therefore, the Gigabit port on the Catalyst 3560 is connected to a Fast Ethernet (100 Mbps) port on the Catalyst 6500 in this network diagram. S1>enable Use the OIT to view an analysis of show command output. When creating a trunk, you must choose a trunking protocol. VLANs divide broadcast domains in a LAN environment. These ISL ports are also known as E-ports. Note: A trunk port is a port that is configured to carry traffic for all the VLANs on a switched network, Trunk ports mark frames traffic with unique identifying tags – either 802.1Q tags or Inter-Switch Link (ISL) tags as they move between switches. 0. eval(ez_write_tag([[300,250],'itigic_com-box-3','ezslot_3',114,'0','0']));Knowledge about trunks adds a lot of value in ensuring good performance of our local networks.
