SNMP

QoS

Quality of Service (QoS) is a term covering several initiatives to maximize the voice quality heard at both ends of a call that originates or terminates on an IP-based telephone. These initiatives include various prioritization schemes to offer voice packets a larger or prioritized share of network resources. These schemes include standards such as:

IEEE’s 802.1D and 802.1Q,

the Internet Engineering Task Force’s (IETF’s) “Differentiated Services,”

RTP Control Protocol (RTCP),

Resource ReSerVation Protocol (RSVP), and

port-based priority schemes such as UDP port selection.

Documentation for your LAN equipment details the extent to which your network can support any or all of these initiatives. See Server Administration on page 43, for some implications of QoS for the 4600 Series IP Telephones.

As of Release 1.7, both the 4620 and 4630 families of IP Telephones provided network audio quality information to the end user. This network audio quality information might be useful to the LAN Administrator. As of Release 1.8, all 4600 Series IP Telephones provide some level of detail about network audio quality. For specific information, see Network Audio Quality Display on 4600 Series IP Telephones on page 77.

SNMP

Simple Network Management Protocol (SNMP) is a family of standards-based protocols and procedures to allow vendor-independent data network management. Using a simple set of protocol commands, an SNMP-compliant device stores information in standard format in one or more Management Information Bases (MIBs). Usually, devices support the standards-specific MIB termed MIB-II. In addition, devices can define one or more “custom MIBs” that contain information about the device’s specifics.

As of Release 1.1, the 4600 Series IP Telephones are fully compatible with SNMPv2c, a later version of SNMP, and with Structure of Management Information Version 2 (SMIv2). The telephones respond correctly to queries from entities that comply with earlier versions of SNMP, such as SNMPv1. “Fully compatible” means that the telephones respond to queries directed either at the MIB-II or the Custom MIB. The 4600 Series IP Telephone Custom MIB is read-only. Read-only means that the values therein cannot be changed externally by means of network management tools.
