multi vlan on single port

Hi All

I would like to create multi vlan on my existing cisco switch 2960S for our new IPT project, existing i have a default vlan , and would like to create a voice vlan for cisco ITP , just wonder how do i create multi vlan on single port, i have search through internet and found below command, but it shows command invalid, is it my version of the switch doesnt support "switchport mode multi" command ? and i found that from other post, if multi doesnt support on this switch model, there is another solution, they suggest to use turnk ? can you explain how to do that ? i though there is only single port need to form trunk link to other switch, Hope you can help with my problem, Thx !

multi vlan on single port

am i allow to assign fix ip in cisco ip phone ? or it must assigned by dhcp server ? and also for telephone number


multi vlan on single port

You can use static addressing though it is a lot of additional administration. Phone number assignment is done by whatever you are using as a call control agent - Call Manager, CM Express or something else.

multi vlan on single port

Hi mfurnival

For below command, correct me if i,m wrong, is below all the steps to assign mutli vlan to a single switch port, while ip phone access port is connected to pc, anything else i miss ? Thx for help

1 VLAN for VOICE        and 1 VLAN for DATA

interface GigabitEthernet0/2     <--- this switch port is connected to ip phone

Switch(config-if)#switchport voice vlan 10    <---  assign this GigabitEthernet0/2 to voice vlan

Switch(config-if)#switchport access vlan 20     <-- at the same time assign data vlan to GigabitEthernet0/2 , what about my data is using default vlan, i can kindly type "switchport access vlan 1 ? 

Blow command is to configuring Cisco IP Phone Voice Traffic

Switch(config-if)# mls qos trust cos
Switch(config-if)# switchport voice vlan dot1p
Switch(config-if)# end

Below command is to configuring the Priority of Incoming Data Frames

Switch(config)# interface gigabitethernet0/1
Switch(config-if)# switchport priority extend trust
Switch(config-if)# end
