Routers only support Dot1Q encapsulation. A port on a Cisco switch is either an access port or a trunk port. Step 7 Router#configure terminal Router(config)#voice-port 1/0/0!Enters voice-port configuration mode Router(config-voiceport)#signal loop-start!Enables loop-start signaling Router(config-voiceport)#ring number 3!Sets FXO port to answer after three rings Router(config Example 17-1 shows a full example of the 802.1Q trunking configuration required on Router B1 in Figure 17-2 . That kind of a setup consists of a router and a switch connected through one Ethernet link configured as an 802.1q trunk link. The bandwidth calculation for the Location is not the same as configured in the router’s policy-map/Interface, so don’t fall into this trap.Interface, so don’t fall into this trap. Step 5 Router(config-if)# switchport nonegotiate Configures the trunk not to use DTP. it will not attach or read vlan tags on frames sent or received by it. How should I configure In this article we will cover the sample configuration for configuring the SIP Trunk to more than one Service provider on Cisco Unified Border Element (CUBE). Before diving into the configuration part, lets review a bit of theory related to This chapter discusses the router side of that trunking configuration; the matching switch interface would need to be configured with the switchport mode trunk command. Step 3 In this lesson, we will learn how to configure VLANs on Cisco switches and their assignments to interfaces. This article explained the use of router-on-a-stick configurations and showed how you can configure an 802.1q trunk link between a Cisco switch and router. I didn't think access since that would signify a host end point on the other end The kind of port that can read the incoming frames with extra vlan tagged information attached to them, is a configured trunk port. How to Configure Trunk Port on Cisco Switch To activate Trunk and examine its logic, open Packet Tracer and create a network topology as shown in the following illustration. A trunk port can have two or more VLANs configured on the interface; it can carry traffic for several VLANs simultaneously. An interface that is shutdown will not send or receive traffic. CME Router Configuration: 1.) The VLAN configuration is as follows: VLAN 10 = Data VLAN 20 = Servers **Note you can add as many This configuration is known as a router-on-a-stick. I'm using a single VLAN to isolate guest network traffic between Ubiquiti AP's and the gateway router (Ubiquiti ER-X). The following output shows the commands used to reset all trunking characteristics of a trunking interface to the default settings. Step 6 Router(config-if)# switchport port-security Enables port security on the trunk. Solved: The switch is configured with access vlan 10 and voice vlan 20. First, we will configure the port connected to 2611XM’s Fa0/1 interface to be a trunk on the switch. port 46 is set up also as a trunk port that connects to a cisco router. There are two parts in this article: Sample configuration & Requirement from SIP Trunk Service Provider So I plugged the switch into it via its configured trunk port, and configured 4 sub interfaces on the router 1800 and all seemed happy as larry and working. SG200 - VLAN trunk - simple configuration to pass VLAN tagged traffic? We will configure the trucking (Trunk) with cisco ASA and after that we will allow the LAN (Inside network behind firewall) to access the internet (8.8.8.8 & 4.4.4.4). The router you are using for Inter-VLAN routing must be compatible and support Inter-Switch Link (ISL) which is a Cisco Systems proprietary protocol, and IEEE 802.1q frame format for routing on the Fast Ethernet interfaces. I'm not sure if I should set up the server's switchport interface (GE 0/1/0) as an access port or a trunk port. Multiple layer 3 interfaces are then The router uses just a single interface connected to a trunk port on the switch. The configuration you posted for port 46 should be applied to port 3 that connects to the EX2200. For the router config, I have created a new VLAN 20 for the server network. Learn all the basics on vlans, trunking, 802.1q, native vlans, and inter vlan routing or routing on a stick for Cisco CCNA Studies. Router-on-a-stick configurations are extremely useful in environments where no layer-3 switch exists, providing Inter-VLAN routing services with a single router and one interface - cutting down seriously the costs for internal routing. interface GigabitEthernet1/0/45 description ZD1000 switchport trunk encapsulation dot1q switchport access vlan 10 switchport trunk allowed vlan 1,10,50,130,150,160 switchport mode trunk spanning-tree portfast end ciscoswitch# *Router A router can be configured as an end device, where it will act just as a PC, i.e. Router# configure terminal Enters global configuration mode. You can connect a Cisco switch and router via 802.1q trunking. Configuration on the switch The switch has the following configuration on its trunk port, GigabitEthernet 0/5 Commands configure terminal interface GigabitEthernet 0/5 switchport trunk native vlan 1 Access ports also carry traffic that comes from only the VLAN assigned to the port. Setup a trunk group name. Trunk Within this example we configure fe-0/0/0 as a trunk and only allow vlans 100, 110 and 120 across. Switch Port Configuration - Shutdown By default on most Cisco switches, all interfaces will be in an administratively shutdown state. Access ports belong to a single VLAN and do not provide any identifying marks on the frames that are passed between switches. Thank you for your answer , I really appreciate it but I need to configure the same port as a promiscuous and trunk port the configuration that is available in this site is for the catalyst 4500 switches and not for 3560 switches, I have tried the following commandes 1 Cisco Router named - R1 1 Cisco Switch named - S1 1 PC named - PC1 1 Server named - SRV1 **Note that the link between SW1 and R1 is a trunk link. trunk group FXO-4PORTS description ***Analog Trunk Group*** hunt-scheme sequential both down ... if we want to allow inside-1 LAN to reach 8.8.8.8 and 4.4.4.4 then below configuration will be If you choose to use an access port, the router will form an adjacency only over the VLAN defined in that access port. The Router interface can be divided into two subinterfaces, with each subinterface belonging to the appropriate VLAN. In the below example we will configure a basic “router on a stick” configuration. There … Router(config-if)# switchport mode trunk Configures the port to trunk unconditionally. Step 1 Perform VLAN creation on Cisco Switch before enabling this protocol. The command to reset the switch port to an access port and, in effect, delete the trunk configuration is also shown. Port security Types of memory on a Cisco device Configure Cisco router as DHCP server Configure NTP on a Cisco router Cisco Discovery Protocol (CDP) overview Map hostnames to IP addresses Configure Cisco device as DNS client Extended ping command Router on a stick approach – Cisco configuration A router on a stick is one of the ways to allow routing between VLANs. Router-on-a-Stick Inter-VLAN Routing Verification (4.2.6) In addition to using ping between devices, the following show commands can be used to verify and troubleshoot the router-on-a-stick configuration. SIP is Cisco's recommended protocol for Voice Gateway & CUCM interconnection. This is the most comprehensive guide for Cisco SIP Gateway configuration.
