(Optional) Configured interface
configuration is not necessary if the VoIP supplicant is using a power adapter. See
"Configuring PoE (CLI Procedure)" on page 3315.
Instead of using a regular telephone, you connect an IP telephone directly to the switch.
An IP phone has all the hardware and software needed to handle VoIP. You also can
power an IP telephone by connecting it to one of the Power over Ethernet (PoE) interfaces
on the switch.
To configure VoIP on an EX Series switch to support an IP phone that does not support
LLDP-MED, add the port to which you want to connect the IP phone as a member of the
voice VLAN and configure the data VLAN as the native VLAN on the EX Series switch.
This configuration ensures that the voice traffic and data traffic do not affect each other.
In this example, the interface ge-0/0/2 on the EX4200 switch is connected to a
non-LLDP-MED IP phone.
NOTE: The implementation of a voice VLAN on an IP telephone is
vendor-specific. Consult the documentation that came with your IP telephone
for instructions on configuring a voice VLAN. For example, on an Avaya phone,
you can ensure that the phone gets the correct VoIP VLAN ID even in the
absence of LLDP-MED by enabling DHCP option 176.
To configure VoIP without LLDP-MED or 802.1X authentication:
To quickly configure VoIP, copy the following commands and paste them into the switch
terminal window:
[edit]
set vlans data-vlan vlan-id 77
set vlans voice-vlan vlan-id 99
set vlans data-vlan interface ge-0/0/2.0
set ethernet-switching-options voip interface ge-0/0/2.0 vlan voice-vlan
set ethernet-switching-options voip interface ge-0/0/2.0 forwarding-class assured-forwarding
set interfaces ge-0/0/2 unit 0 family ethernet-switching vlan members voice-vlan
set interfaces ge-0/0/2 unit 0 family ethernet-switching native-vlan-id data-vlan
Configure VoIP:
Configure the VLANs for data and voice:
1.
[edit vlans]
user@switch# set data-vlan vlan-id 77
user@switch# set voice-vlan vlan-id 99
Configure the VLAN data-vlan
2.
[edit vlans]
user@switch# set data-vlan interface ge-0/0/2.0
