Join Denise Allen-Hoyt for an in-depth discussion in this video Exploring the types of VLANs, part of Up and Running with Cisco CLI Switch Configuration.
- Cisco switches have one VLAN by default, which is VLAN 1. All of the ports on the switch are assigned to VLAN 1, also by default. I'm gonna show you how the VLAN 1 is displayed on the Cisco switch. I'm gonna go ahead and click on the West switch, click on the CLI, hit Enter on the keyboard, I'm gonna go ahead and expand the window. I type console, console0, ena, for enable, secret1, that's the enable password, and then I go ahead, issue the command show vlan brief.
The output of the show vlan brief displays my VLAN , the default VLAN 1, it is active, and you can see that all of the ports on this switch have been assigned to this VLAN. I cannot change the name of this VLAN, I'll show you. I go config t, I go into VLAN 1, and I try to change its name, let's say I want to call it "wireless". Notice it says that the default VLAN may not have its name changed. So, Cisco switches will always have the one VLAN, by default, with the name of default.
