Internet Protocol (IP)

Cisco Cius Administration Guide, Release 9.2(3)

Purpose

HTTP is the standard way of

transferring information and moving

documents across the Internet and the

web.

HTTPS is a combination of the

Hypertext Transfer Protocol with the

SSL/TLS protocol to provide

encryption and secure identification of

servers and for transferring Cisco Cius

firmware images.

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.

The IEEE 802.11 standard specifies

how devices communicate 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.

IP is a messaging protocol that

addresses and sends packets across the

network.

Overview of Cisco Cius

Usage notes

Cisco Cius uses HTTP for XML services

and for troubleshooting purposes.

Web applications with both HTTP and

HTTPS support have two URLs

configured.

Cisco Cius implements the IEEE 802.1X

standard by providing support for the

following authentication methods:

EAP-FAST and EAP-TLS, PEAP, and

CCKM.

After 802.1X authentication is enabled

on Cisco Cius, disable the PC port on

the media station and voice VLAN. See

the

Supporting 802.1X Authentication

on Cisco Cius, on page 19

for additional

information.

The 802.11 interface is a deployment

option for cases when Ethernet cabling

is unavailable or undesirable.

To communicate using IP, network

devices must have an assigned IP

address, gateway, and netmask.

IP address, gateway, and netmask

identifications are automatically assigned

if you are using Cisco Cius with DHCP.

If you are not using DHCP, you must

manually assign these properties to each

Cisco Cius locally.
