DELL Networking. VLAN Configuring

DELL, vlan, voice vlan

Configuring VLAN for DELL switches (depending on the version of the OS switch syntax may vary slightly.

Before you configure the VLAN on the switch interfaces, you must make the switch in the VLAN database and create a VLAN interface:

console(config)# vlan database
console(config-vlan)# vlan 1972
console(config-vlan)# end
console(config)# interface vlan 1972
console(config-if)# name Marketing
console(config-if)# end

Then you can perform VLAN configuration on the switch ports:

console(config)# interface ethernet 1/e8
console(config-if)# switchport mode access
console(config-if)# switchport access vlan 23
console(config-if)# end
console(config)# interface ethernet 1/e9
console(config-if)# switchport mode trunk
console(config-if)# switchport mode trunk allowed vlan add 23-25
console(config-if)# end
console(config)# interface ethernet 1/e11
console(config-if)# switchport mode general
console(config-if)# switchport general allowed vlan add 23,25 tagged
console(config-if)# switchport general pvid 25

VLAN Configuring for Voice over IP (VoIP)

Most PC users to connect through IP-phone to save ports on the switch. To a PC did not get voice traffic, generate traffic tagging for IP-phones, this mixing of traffic to untagged traffic for PC. In this case, the PC ignores tagged traffic, and IP-phone is configured to accept tagged traffic.

Below is a listing of the configuration of voice VLAN:
