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. “Shutdown” shuts down the interface, while “no shutdown” brings up the interface.One of the typical configuration activities you’ll perform on a Cisco Switch is to manipulate VLANs.

Sets a host name to the current Cisco network deviceĪn enable mode command that copies files from one file location to anotherĪn enable mode command that saves the active config, replacing the startup config when a Cisco network device initializesĪn enable mode command that merges the startup config with the currently active config in RAMĪn enable mode command that deletes the startup config Logs you into enable mode, which is also known as user exec mode or privileged modeĮnters interface configuration mode for the specified fast ethernet interfaceĪn exec mode command that reboots a Cisco switch or router Here is a Cisco commands cheat sheet that describes the basic commands for configuring, securing and troubleshooting Cisco network devices. The basic CLI commands for all of them are the same, which simplifies Cisco device management. Almost all Cisco devices use Cisco IOS to operate and Cisco CLI to be managed.
