One RADIUS server
As well as configuring a VoIP for interface
ge-0/0/2
, you configure:
•
802.1X authentication. Authentication is set to
multiple
supplicant to support more
than one supplicant's access to the LAN through interface
ge-0/0/2
.
•
LLDP-MED protocol information. The switch uses LLDP-MED to forward VoIP
parameters to the phone. Using LLDP-MED ensures that voice traffic gets tagged and
prioritized with the correct values at the source itself. For example, 802.1p class of
service and 802.1Q tag information can be sent to the IP telephone.
NOTE:
A PoE configuration is not necessary if an IP telephone is using a
power adapter.
