The Correct Command To Name Vlan 35 As Dhcp_vlan

To name VLAN 35 as dhcp_vlan, you would typically use a network switch configuration command. The exact command may vary depending on the brand and model of the network switch. I can guide you on how to typically configure VLAN names on network devices. 

For Yealink Phone devices Or Video conferencing Devices, you would generally use the command line interface (CLI) to configure VLANs. Here is a general example of how you might name a VLAN on a network switch:

configure terminal
vlan 35
name dhcp_vlan
end

Please note that the exact commands can vary depending on the specific model and firmware version of your Yealink device. If you need detailed instructions, I recommend consulting the user manual for your specific device model or contacting Yealink support directly.

Below are examples for a few common othne brands:

Cisco IOS

For Cisco switches running IOS, the command is:

conf t

vlan 35

name dhcp_vlan

end

Juniper Junos

For Juniper switches running Junos, the command is:

set vlans dhcp_vlan vlan-id 35

HP ProCurve

For HP ProCurve switches, the command is:

vlan 35

name "dhcp_vlan"

exit

Dell Networking

For Dell Networking switches, the command is:

interface vlan 35

name dhcp_vlan

Configuring DHCP Option On Yealink IP Phone

DHCP VLAN is enabled on IP phones by default. You can configure DHCP VLAN via web user interface or using the configuration file. You can also configure the DHCP option. The default DHCP option is 132. 

To configure DHCP VLAN feature via web user interface: 

 1. Log into the web user interface with the administrator credential. The default administrator user name and password are both "admin".

 2. Click on Network->Advanced.

 3. In the VLAN block, select the desired value from the pull-down list of DHCP VLAN Active.

 4. Enter the desired value in the Option field. The default value is 132.

 5. Click Confirm to accept the change. The web user interface prompts the warning"Some settings you changed take effect when you restart your machine! Do you want to reboot now?".

 6. Click OK to reboot the IP phone. 

To configure DHCP VLAN feature using the configuration file: 

 1. Add/Edit DHCP VLAN parameters in the configuration file.

 2. Store the configuration file to the root directory of the provisioning server. 

The following shows an example of DHCP VLAN configuration in the configuration file: 

network.vlan.dhcp_enable = 1 

network.vlan.dhcp_option = 132
