    Hi,

    First You need probably a separate VLAN for voip, in my example it is vlan 10.

    When You have a port already configured for any access VLAN (in my example it is vlan 2 for normal network traffic), You just need to add voip like below.

        ge-0/0/45 {
            unit 0 {
                family ethernet-switching {
                    port-mode access;
                    vlan {
                        members 2;
                    }
                }
            }
        }

    set ethernet-switching-options voip interface ge-0/0/45.0 vlan 10
    set ethernet-switching-options voip interface ge-0/0/45.0 forwarding-class expedited-forwarding

    Hi,

    Can you kindly confirm the full requirements?

    • Do the ports connected to the phone need 802.1x (RADIUS) authentication?
    • Is PoE (Power of Ethernet) required for the Cisco Phones?
    • Do we have a PC connected inline with the Cisco Phones on the same switch port?

    Regards

    Hi,

    If no PC is connected to the IP Phones, then the voice VLAN configuration is unnecessary. The port can be a simple access port in the required VLAN. If there is a need to connect a PC to the IP Phones, then the voice VLAN can be useful, as it can let the IP Phone tag the Voice VLAN packets (using LLDP-MED information) and leave the data VLAN untagged.

    As you requested specific steps, the simplest configuration can be as follows (no Voice VLAN shown here):

    a) Configure the VLAN

    set vlans ip-phone vlan-id 100

    b) If the gateway of the IP phones resides on this switch, then configure the irb interface and associate it with the configured VLAN

    set interfaces irb.100 family inet address 10.10.100.1/24
    
    set vlans ip-phone l3-interface irb.100

    c) Configure the interface connected to the IP Phone as an access-port in the vlan

    set interfaces ge-0/0/0.0 family ethernet-switching interface-mode access vlan members ip-phone

    d) Enable poe on the interface.

    set protocols lldp-med interface ge-0/0/0.0
    
    set poe interface ge-0/0/0.0

    You will need additional configurations if the switch needs to be the DHCP server or act as the DHCP relay for the IP Phones. Similarly, for specific CoS configurations.

    Regards
