APPLICATION NOTE - Deploying IP Telephony with EX Series Ethernet Switches

In the second functional block (below), two VLANs are defined: one for voice and one for data. The actual VLAN IDs

used on this example are arbitrary; the EX Series allows VLAN ID configurations up to 4096.

user@switch# set vlans voip-only vlan-id 99

user@switch# set vlans data-only vlan-id 10

In the third functional block (below), the interface “ge-0/0/1” has been configured as an access port belonging to the

data VLAN (“data-only”). Notice that there is no configuration needed for the voice VLAN, which is covered in the next

section.

user@switch# set interfaces ge-0/0/1 unit 0 family ethernet-switching port-mode

access

user@switch# set interfaces ge-0/0/1 unit 0 family ethernet-switching vlan member

data-only

In the fourth functional block (below), the Voice VLAN feature is configured under the Ethernet-switching-options

stanza with the voip option (see the “ethernet-switching-options voip” command below). Here the actual VLAN to be

used for voice will be defined, as well as the level of service that will be provided for traffic received on that VLAN—in

this example, “expedited-forwarding.”

user@switch# set ethernet-switching-options voip interface ge-0/0/1.0 vlan voip-

only

user@switch# set ethernet-switching-options voip interface ge-0/0/1.0 forwarding-

class expedited-forwarding

In the fifth functional block (below), the configuration is committed in Junos OS, making it active.

user@switch# commit

Upon completion, the LLDP-MED configuration can be verified on the EX Series, as shown below.
