All rights reserved.CIPT2 v SNMP Refresher SNMP is a protocol that facilitates the exchange of management information between network devices (for example, Cisco Unified CallManager and network management software) SNMP versions: –SMNPv1 –SNMPv2 –SNMPv3 Consists of three key components: –Managed devices –Agents –Network management systems

5 © 2006 Cisco Systems, Inc. All rights reserved.CIPT2 v Cisco Unified CallManager Release 5.0 Supported MIBs CISCO-CCM-MIBContains information about the local Cisco Unified CallManager and its associated devices. CISCO-CDP-MIBEnables Cisco Unified CallManager to advertise itself to other Cisco devices on the network. CISCO-SYSLOG-MIBProvides fault and recovery notification via syslogs. Generates trap for every syslog message with severity above the user-set severity level. MIB2 (Standard)Provides access to variables that are defined in RFC 1213, such as interfaces and IP. SYSAPPL-MIBProvides information about the installed applications, components, and processes that are running on the system. HOST-RESOURCES-MIB (Standard)Provides host information, such as storage resources, process tables, device information, and installed software base.

13 © 2006 Cisco Systems, Inc. All rights reserved.CIPT2 v Enabling Dependency Records Choose Cisco CallManager Administration > System > Service Parameters. Set the value to True to display dependency records. Displaying dependency records leads to high CPU usage and takes time; it executes in a low-priority thread.

14 © 2006 Cisco Systems, Inc. All rights reserved.CIPT2 v Accessing Dependency Records Dependency records can be found on many of the configuration pages in Cisco Unified CallManager Administration. In this example, Choose Dependency Records to see all devices or items using device pool Default.

15 © 2006 Cisco Systems, Inc. All rights reserved.CIPT2 v Dependency Records Summary The Summary window shows the dependency records only by type and number. To get detailed information about a type, click the entry. From the detailed list, click an entry to get to the configuration page of that device.

25 © 2006 Cisco Systems, Inc. All rights reserved.CIPT2 v QRT Overview QRT is a voice-quality reporting tool integrated into Cisco Unified CallManager. QRT allows users to report calls with quality problems or general problems such as missing dial tones by pressing the QRT softkey on the IP phone. Details about affected call are sent to Cisco Unified CallManager and stored on the server hard disk. Stored data can be analyzed using QRT Viewer (part of Cisco Unified CallManager RTMT). Two user interview modes are supported.

26 © 2006 Cisco Systems, Inc. All rights reserved.CIPT2 v User Interface Modes Two user interface modes are supported. –Interview mode: User is presented with extended menu choices. This mode lets the user provide additional details related to audio quality (reason codes). It also lets the user submit a report for problems not related to audio quality, such as phone recently rebooted or cannot make calls. –Silent Mode (default): User is not presented with extended menu choices. When users press the QRT softkey, streaming statistics are collected and report is logged without further user interaction. Cisco Extended Functions service parameter named Display Extended QRT Menu Choices is used to configure the mode.

27 © 2006 Cisco Systems, Inc. All rights reserved.CIPT2 v Extended Menu Choices: Interview Mode User presses QRT softkey. 2. User is prompted to select a problem category. 3. User is prompted to choose a reason code. 4. User is sent an acknowledgment.

28 © 2006 Cisco Systems, Inc. All rights reserved.CIPT2 v Extended Menu Choices: Silent Mode User presses QRT softkey. 2. User is sent an acknowledgment.

29 © 2006 Cisco Systems, Inc. All rights reserved.CIPT2 v QRT Configuration Steps 1. Activate the Cisco Extended Functions service (feature service) in Cisco Unified CallManager Serviceability. 2. Set the Extended Functions service parameter Display Extended QRT Menu Choices to interview mode. 3. Add the QRT softkey to the phones that should be able to use QRT for these states: –Connected –Connected Conference –Connected Transfer –On Hook

32 © 2006 Cisco Systems, Inc. All rights reserved.CIPT2 v Summary Cisco Unified CallManager, as part of the Cisco Unified Communications solution, supports management by SNMP. Cisco Unified Operations Manager is the recommended SNMP management system to manage Cisco Unified Communications deployments. Dependency records help in determining which configuration elements of Cisco Unified CallManager are associated with other configuration elements. Cisco Unified CallManager Dialed Number Analyzer is a tool to diagnose, tune, and test deployed dial plans as well as to test dial plan changes before deployment. QRT helps administrators to identify and resolve quality problems in an IP telephony network. End users can use this tool to report errors.
