Network Protocol
Cisco Desktop Collaboration
Experience DX600 series phones
implement the IEEE 802.1X
standard by providing support for
the following authentication
methods: EAP-FAST and
EAP-TLS.
When 802.1X authentication is
enabled on the phone, you should
disable the PC port and voice
VLAN. See
Support, on page 24
for additional
information.
The IEEE 802.1X standard defines a client-server-based
access control and authentication protocol that restricts
unauthorized clients from connecting to a LAN through
publicly accessible ports.
Until the client is authenticated, 802.1X access control allows
only Extensible Authentication Protocol over LAN (EAPOL)
traffic through the port to which the client is connected. After
authentication is successful, normal traffic can pass through
the port.
IEEE 802.1X
The 802.11 interface is a
deployment option for cases when
Ethernet cabling is unavailable or
undesirable.
The IEEE 802.11 standard specifies how devices
communication over a wireless local area network (WLAN).
802.11a operates at the 5 GHz band and 802.11b and 802.11g
operate at the 2.4 GHz band
802.11.n operates in either 2.4 GHz or 5Ghz band.
IEEE 802.11a/b/g/n
To communicate using IP, network
devices must have an assigned IP
address, domain name, gateway,
and netmask.
IP addresses, subnets, and gateway
identifications are automatically
assigned if you are using the Cisco
DX650 with Dynamic Host
Configuration Protocol (DHCP). If
you are not using DHCP, you must
manually assign these properties to
each phone locally.
IP is a messaging protocol that addresses and sends packets
across the network.
Internet Protocol (IP)
The Cisco DX650 supports LLDP
on the PC port.
LLDP is a standardized network discovery protocol (similar
to CDP) that is supported on some Cisco and third-party
devices.
Link Layer Discovery Protocol
(LLDP)
The Cisco DX650 supports LLDP
on the PC port.
LLDP-MED is an extension of the LLDP standard for voice
products.
