In this example, workstation1 has been configured with default gateway 10.10.10.1. As the configuration will become increasingly complex, I encourage you to read them in order. Now that the VLANS are configured in the switch database we can configure the Trunk link between the switch and router. Since the link between SW1 and the router is an L2 trunk you can simply remove the gateway interfaces from SW1 and configure them on your router. For interVLAN routing, be sure to configure the default gateway on all workstations that connect to the switches. This switch port must be TRUNK port: SWITCH1: ———— SVI) for each VLAN with the respective IP address. configure terminal int fa0/1 switchport mode trunk switchport trunk encapsulation dot1q. Certain show commands are supported by the Output Interpreter Tool (registered customers only) , which allows you to view an analysis of show command output. This document provides a sample configuration for Fast EtherChannel (FEC) and IEEE 802.1Q trunking between Cisco Catalyst Layer 2 (L2) fixed configuration switches and a Cisco router.

This configuration ensures availability and stability of the VoIP service, especially during peak traffic hours in your network. Assume that we will use port 0/23 of SWITCH 1 to connect the router. Because VoIP implementations require you to separate the data and voice network in order to route packets between them, you need either a layer 3 switch or a router. 3560). Open a web browser. In Part 2, you will create VLANs as specified in the table … What should be default gateway on the 2 Access switches and the CORE switch, also what static route should be on router to reach all subnets(VLANs) created on these 3 switches. PwC Italy utilized Cisco SD-Access to modernize their networ... Smart Licensing using Policy - Licensing simplified. There are three options available in order to enable routing between the VLANs: Router with a Separate Physical Interface in each VLAN; Router with a Sub-Interface in each VLAN; Utilizing a Layer 3 Switch; The remainder of this article will explore these three options and their configuration. Each of these modules supports a maximum of six EtherChannels, with up to eight ports in an EtherChannel bundle. Change the switchport mode on interface F0/1 to force trunking. If for some reason this doesn't work for you...please let me know what type of device your router is and we should be able to figure it out at that point. The router has 2 FE ports one for WAN and one for LAN which is connected to F0/24 on SW1 which has unpruned trunk as suggested by you. EtherChannel provides incremental speeds between Fast Ethernet (FE) and Gigabit Ethernet (GE) through the group of multiple equal-speed ports into a logical port channel. Your router would be configured like: int fa0/0 (interface connected to switch). On an 802.1Q trunk, all VLAN packets except the native VLAN are tagged. John Note: The Catalyst 2950 switch commands and configuration in this document are applicable to switches that run Cisco IOS Software Release 12.1(6)EA2 and later. Remaining 2 Cisco3560's(Access) are connected to Gi0/1 and Gi0/2 on the 1st switch-CORE via gi0/1 . If you want to create intervlan routing between all three VLANs 2,3,4 then you need to connect a router on one trunk port of ANY switch (either switch 1 or switch 2) and then configure DOT1Q subinterfaces on the router. The purpose of the configuration of trunking between the switch and the router is to provide interVLAN communication. Now, let’s find out what VTP can do for you. In Part 3, you will manually configure interface F0/1 as a trunk. The Catalyst L2 fixed configuration switches include the 2900/3500XL, 2940, 2950/2955, and 2970 switches. if i have a switch and don`t configure any vlans on it only default vlan (vlan 1) and configure int vlan 1 and give him IP add. There are a number of reasons you will need to install a certificate on to an IOS \ IOS XE device. - no interfaces should need to be configured on these switches...SW1 will know with port to send host traffic to via mac-addresses as will each access switch. I did what you recomended and I can ping from host to SW1 gateway with in each VLAN but can't ping to the router from any switch or host. On the router I will have route to all VLANs I have to createe on all these 3 switches. TRK1 has ALL Vlan trunked coming in from Draytek router Note: Native VLAN is the VLAN that you configure on the Catalyst interface before you configure the trunking on that interface. With this command, the interface changes to permanent trunking mode. But you can use any other router that supports EtherChannel and 802.1Q trunking to get the sa… You can connect a Cisco switch and router via 802.1q trunking. - this will also allow for the inter-VLAN routing...no need for router on a stick when using a L3 switch (e.g. The switch to switch connection is trunk allowing all VLANs created on all these 3 switches. 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. **NOTE:  For the static route being configured on the Router, be sure to only include the range of networks configured on SW1. On all three switches I have created multile VLANs and assigned ports to these VLAN. Router:- Draytek 3900 . In my opinion this is more scalable and aligns better with Cisco's campus design model. The show interfaces interface-id switchport command displays the switchport configuration of the interface in the Administrative Mode field and the Administrative Trunking Encapsulation field of the output. You can use the show interfaces interface.subinterface command in order to verify the trunk configuration. This type of interface can be assigned only to a single VLAN. The Catalyst 2940 and 2955/2950 switches do not support Inter-Switch Link Protocol (ISL) trunking due to hardware limitations. All rights reserved. You create a subinterface on the router for each VLAN. Awesome Rettuc- Everythign worked as a chime   A big thanks for all the help provided!!! First to give the overview of topology- I have an enviornment of 3 X 3560G of which I have 1st switch-CORE(f0/10) connecting to the VPN router(CE) interface-f0/0. So those are the two ways you can configure your environment... remove VLAN interfaces from SW1 and add them to the router instead.

To make it easier, Cisco developed VLAN Trunking Protocol (VTP). The part that im having problems is pinging from wkstn A to wkstn B. I used a different class of IP's but followed the directions as careful as possible. You must configure the native VLAN in the same way on each side of the trunk. In a campus network, you configure trunking over an EtherChannel link to carry the multiple-VLAN information over a high-bandwidth channel. VIPs) are configured on the same L3 device hosts from one VLAN should be able to ping hosts in another VLAN. show interfaces port-channel channel-number. If your switches support both ISL and 802.1q frame tagging protocols, you also need to use the switchport trunk encapsulation {dot1q | isl} command to define the type of trunking. S1 (config)#int fa0/1 S1 … This device will be were all of your HOST gateways will live for these networks so the IP's assigned to each SVI would ideally be x.y.z.1 (e.g. Make sure to do this on both switches. You can use the show interfaces port-channel channel-number command in order to verify the port channel interface and the channel member ports. Our example is based on a scenario you are most likely to come across when dealing with VoIP networks. Background:- HPE Office COnnect 1920 Series JG928A Switch . If you don’t configure a default gateway then VLAN1 will be unable to send traffic to another network. This would set up trunking for 2 vlans on a switch and the router would provide the routing for traffice between the 2 vlans via trunking. sorry for leaving that detail out..for the traffic to get from either switch to the router and back you will need to configure a routing protocol, static routes or a default route on both sw1 (reference the diagram in my previous response) and the the neighboring router. switchport trunk encapsulation dot1q ... How to configure a trunk port on a Cisco 2960 switch? Use this table in order to determine which router platforms support FEC as well as 802.1Q trunking features: 1 An exception to EtherChannel support on Cisco 2600, 3600, and 3700 series routers is when you have installed either the NM-16ESW or NM-36ESW Ethernet Switch Network Module.
