Media Server (Switch) Administration
Issue 5 April 2010 35
!Important:
Important: Avaya Aura Communication Manager administration always takes precedence
over manual administration of IEEE 802.1P/Q data.
The four IEEE 802.IP/Q QoS parameters in the telephones that can be administered on the IP
Network Region form are L2Q, L2QVLAN, L2QAUD, and L2QSIG. To set these parameters at
the switch, see “About Quality of Service (QoS) and voice quality administration” in
Administration for Network Connectivity for Avaya Aura™ Communication Manager (Document
Number 555-233-504). To set these parameters manually see the 1600 IP Telephone
Installation and Maintenance Guide. You can specify VLAN ID and VLANTEST values with the
ADDR Local Administrative Option.
Note:
Note: All local administrative procedures are on a phone-by-phone basis.
Administration using Avaya Aura Communication Manager, DHCP, and HTTP
applies to the telephone system itself or to a range of telephones.
NAT
Network Address Translation (NAT) usage can lead to problems that affect the consistency of
addressing throughout your network. All H.323 IP Telephones support NAT interworking.
Support for NAT does not imply support for Network Address Port Translation (NAPT). The
telephones do not support communication to the PBX through any NAPT device.
NAT requires specific administration on the media server. A direct Avaya IP Telephone-to-Avaya
IP Telephone call with NAT requires Avaya Aura Communication Manager Release 3.0 or
greater software. For more information, see Administration for Network Connectivity for Avaya
Aura™ Communication Manager (Document Number 555-233-504) on the Avaya support Web
site.
DIFFSERV
The DiffServ values change to the values administered on the media server as soon as the
telephone registers. For more information, see Chapter 4 “Network Quality Administration” in
Administration for Network Connectivity for Avaya Aura™ Communication Manager (Document
Number 555-233-504). Unless there is a specific need in your enterprise LAN, Avaya
recommends that you do not change the default values.
