How to enable VLAN1 and VLAN 100 on all ports on a Cisco Catalyst 3560G PEOP-48 Switch

[EduardoRuiz]

I have a set of 3560G switches and would like to configure all the ports to access VLAN1 and VLAN100. Is this possible? If so, can you provide me instructions or guidance on how I can accomplish this? I'm currently accessing the switch via Cisco Network Assistant software.

These are the options that I have when trying to configure each port. - see images below

Thank you in advance.

Hi Eduardo,

Short answer - Yes, But all ports will have to be trunk to allow both vlan traffic. 

Select the Admin mode - 802.1Q Trunk 

Trunk-Vlans allowed ( Add both 1 and 100 ) - 1,100

From the device console you can use the range command to do the same. 
I have some additional questions

1. Why do you want all ports to use both vlans, is one of them a voice vlan ?

Hi  Shaikmohib

Thanks for your comment. Yes, vlan100 is a voice lan. When IP phones are plugged in, they receive and IP address from this range 192.168.100.#. Therefore I need this Vlan to be accessible across the network.

Hey Eduardo use the following setup to enable both VLan

Access Mode Vlan : 1

Voice Vlan : 100 

You can also use CLI to do the same 

switchport mode access vlan 1

switchport voice vlan 100 

Let us know if you still have any issues
