Quality of service

Last Updated : Dec 21, 2012 |

Quality of service is used in IP networks to provide different priority to different applications, users, or to guarantee a certain level of performance to a critical data flow such as voice or video. Differentiated Services or DiffServ is a networking architecture that specifies a simple mechanism for classifying network traffic using a 6-bit field in the header of the IP packets. VLAN (Virtual LAN) is a technology to logically divide a physical network into several logical nets and thus to differentiate traffic.

Procedure

  1. On the phone, press MENU > SETTINGS > ADVANCED > enter your PIN > NETWORK > ETHERNET > VLAN (or press 6,2,2,2,1 from the main menu—you will be asked to enter the PIN).

  2. Configure the DiffServ and VLAN settings and press OK when you are satisfied. Refer to the table below for a brief description of the setting options.

Ethernet setting

Description

SIP DiffServ

Enter a value between 0 and 63 to prioritize the SIP messages.

Media DiffServ

Enter a value between 0 and 63 to prioritize the media packets (voice).

VLAN

By enabling this option, all communication to and from the B179 is done via the VLAN specified under VLAN ID.

VLAN ID

The ID number to be used for the IP telephony VLAN.

VLAN map enable

Enabling VLAN priority mapping from the DiffServ setting.

VLAN prio SIP

Set a value between 0 and 7 to prioritize the SIP messages in the VLAN.

VLAN prio media

Set a value between 0 and 7 to prioritize the media packets in the VLAN.

802.1x

IEEE 802.1X is an IEEE Standard for port-based Network Access Control and is part of the IEEE 802.1 group of networking protocols. It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN.

Procedure

  1. On the phone, press MENU > SETTINGS > ADVANCED > enter your PIN > NETWORK > ETHERNET > 802.1x AUTH (or press 6,2,2,2,2 from the main menu—you will be asked to enter the PIN).

  2. Configure the protocol and press OK when you are satisfied. Refer to the table below for a brief description of the setting options.

Protocol setting

Description

Enable 802.1x

When you enable this option, the B179 asks an authentication server for permission when connected to the LAN.

EAP method

Select which EAP (Extensible Authentication Protocol) method to use: MD5 or TLS.

Username

The device identity in the network.

MD5 password

The password for the device identity when using MD5.

Certificate

Upload a certificate to the Avaya B179 to be used for authentication when using TLS.

Root certificate

The public key in the root certificate is used to verify other certificates when using TLS.

Private key

Upload a private key to the B179 to be used for authentication when using TLS.

TLS password

The password used for encryption of the private key when using TLS.
