They are connected by a single crossover cable. Use Trunk ports for connecting other switches or Axia devices with switches built-in (like a PowerStation Main or QOR or xSwitch). Trunk port configuration example to carry the different VLAN tags between two devices on the same physical link. I've got the default VLAN1 on each switch. Platform: Catalyst 2960-X, Catalyst 3560. The above picture shows that the trunk link is connected to port fa0/24 on both switches. A voice VLAN port is an access port attached to a Cisco IP Phone, configured to use one VLAN for voice traffic and another VLAN for data traffic from a device attached to the phone. *** LACP (Phase 2) ***! SW1(config)# spanning-tree portfast default %Warning: this command enables portfast by default on all interfaces. Voice VLAN . Please note that when connecting to a PowerStation Main, only the GIG ports can be used and they must be properly configured for Trunk operation in the Ethernet Switch configuration of the Element Control Center. Vlan 1 is the default native VLAN of Cisco Switches. The VMPS can be a Catalyst 6500 series switch, for example, but never a Catalyst 2960, 2960-S, or 2960-C switch. I went to school and have some CLI experience but it's been 7+ years. Let’s consider the simplest case when you have to hook up 3 departments of a company to different logical networks (Vlans) using one access layer switch Cisco 2960 (Sometimes they are called switches of the second layer of OSI model).For example we need to organize these networks (Vlan):Sales department (192.168.10.0 255.255.255.0)Accounting department (192.168.20.0 255.255.255.0) The port is lit up on the core switch, but not on the 2960-X uplink port. By default, all switch ports in Layer 2 are configured to operate as access links. I've got a new 2960 switch, and an existing 2960. The problem I'm having is the VLAN's are not passing from the existing to the new. You should now disable portfast explicitly on switched ports leading to hubs, switches and bridges as they may create temporary bridging loops. To participate in VTP, at least one trunk port on the switch stack must be connected to a trunk port of a second switch or switch stack. I'm aware that this may be a simple question. The following Vlans were allowed to use this port as a trunk: 1, 100 and 200. Say we hypothetically have two Cisco 2960 series access switches. Both switches, S1 and S2, are connected at port Fa0/1 (Fast Ethernet 0/1). Following example shows how to create and configure trunk link to carry multiple VLAN traffic and how to configure the native VLAN for a trunk link.. Before you create the trunk link on the switches, make sure both have a native VLAN installed on them. SW1# configure terminal Enter configuration commands, one per line. End with CNTL/Z. interface Ethernet ALL lacp mode port 1/47-48,2/47-48 active lacp aggregation port 1/47-48,2/47-48 enable exit pretty easy Vendor agnostic technology (IEEE 802.1Q) Switch(config)# interface GigabitEthernet 0/0/10 Switch(config-if)# switchport trunk encapsulation dot1q Switch(config-if)# switchport mode trunk We have tried replacing cables, gbics, and all I can think of is that I have the port misconfigured. You can have dynamic-access ports and trunk ports on the same switch, but you must connect the dynamic-access port to an end station or hub and not to another switch. I have a 2960 running IOS 12.2 (25r)SEE1, and trying to configure a trunk for dot1q encapsulation. In our example, the Switch port 40 was configured as a trunk. Don’t forget to save your Switch trunk configuration In this lesson I will demonstrate how to configure a trunk between Cisco Catalyst switches. Let me show you the topology that we’ll use: Above you see a topology with a computer connected to each switch. The Catalyst 2960, 2960-S, or 2960-C switch is a VMPS client. It takes the following statements: switchport trunk allowed vlan 100 switchport mode trunk switchport nonegotiate I'm not sure why I can't change the encapsulation. I configured both for trunking on the uplink port. We’ll put the computers in the same VLAN and create a trunk between the two switches. Here is what I have now: 2960-X Uplink Port. this config works vs a cisco 35XX stack from a ers4850 GTS stack! To carry the different VLAN tags between two devices on the uplink port in example.
