SVIs do not require the no shutdown command to become enabled.Ĭisco IOS switches have physical ports for devices to connect to, but also have one or more switch virtual interfaces (SVIs).

SVIs come preconfigured on Cisco switches.

An SVI is created in software and requires a configured IP address and a subnet mask in order to provide remote access to the switch.

Although it is a virtual interface, it needs to have physical hardware on the device associated with it.

Do this only on a test system, where you can play around and learn how to manipulate VLANs on cisco switch.Last Updated on Novemby Admin What is a characteristic of a switch virtual interface (SVI)? #show vlanĪs a final note, if you don’t know what you are doing, do not execute any of the above commands on production switch, as you might bring down your network. no vlan 192įinally, verify that the VLAN 192 got deleted as shown below. Next, delete the vlan itself as shown below. I.e If you want to delete VLAN 192, assign VLAN 1 to the ports 3 through 6, and just delete the VLAN 192.įirst, assign the default VLAN 1 to ports 3 though 6 as shown below. Let us assume that you want to delete the VLAN 192 (ports 3 though 6) that you just created.ĭeleting a VLAN is as simple as assigning the default VLAN 1 to the ports that are part of the VLAN you want to delete, and delete the VLAN.

Or, you might want to delete a VLAN, just because you’ve created it by mistake. You might want to delete a VLAN, if you are planning to switch the ports assigned to VLAN 192 to a different VLAN.

On a side note, it is always recommended that you upgrade ISO image on your cisco switch to the latest version. swithport access vlan 192 – Indicates that the access to the vlan 192 is enabledĪpart from providing the access to the vlan 192 for the port numbers 3 through 6, you can also specify the following additional switchport configuration parameters (for example, nonegotiate and mode access) config t.interface range gigabitEthernet 1/0/3-6 – Indicates that the port numbers 3 through 6 are assigned to this VLAN.config t – Goes into the configuration mode.In this example, ports 3 through 6 are configured as part of 192 VLAN network. While creating a VLAN you also need to specify the range of ports from the switch that needs to be part of this VLAN network. In the following example, we are creating 192 VLAN network (for 10.10.192.0 network).

In this example, all the ports in this switch ( from 1 through 8 ) are part of the default VLAN 1.ġ default active Gi1/0/1, Gi1/0/2, Gi1/0/3, Gi1/0/4 i.e All the ports in the switch will be connected to the 10.10.192.0 network, then you don’t need to create a VLAN, just use the default VLAN 1.Įvery switch comes with the default VLAN 1 as shown below.

If you are planning to have only one network in your whole switch (for example, 10.10.192.0). While these commands were tested on a cisco catalyst switch 3750 series, similar commands (may be with slight variation to the port number format) should work on all cisco switches. All three of these can be configured in the same physical switch. In one physical cisco switch, you can create multiple VLANs that connects to different network.įor example, a VLAN for 10.10.191.0 network, a VLAN for 10.10.192.0 network, and a VLAN for 10.10.193.0 network. VLAN stands for Virtual Local Area Network. One of the typical configuration activities you’ll perform on a Cisco Switch is to manipulate VLANs.
