TAC Case Priority Definitions To ensure that all cases are reported in a standard format, Cisco has established case priority definitions. Priority 1 (P1)-Your network is “down” or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation. Priority 2 (P2)-Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation. Priority 3 (P3)-Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels. Priority 4 (P4)-You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations. http://www.cisco.com/en/US/partner/ products/sw/netmgtsw/ps4748/products_documentation_roadmap09186a0

Although the TSP trace functionality of Maestro Tools has been replaced with Cisco Unity Diagnostic tool, it is the best of the possible answers. Obtaining TSP Traces CiscoUnity versions 3.1(1) and later use the CiscoUnity Diagnostic Tool, rather than Maestro Tools, to obtain TSP traces. http://www.cisco.com/en/US/partner/products/sw/voicesw/ps2237/ prod_release_note09186a00800d759f.html Setting Skinny Traces using DBMON or TSPMON To learn how to set Skinny traces using DBMON or TSPMON, review the information below. Note: For some Cisco Unity versions, the Technical Support engineer might provide you with a special application called dbmon.exe or tspmon.exe. Each utility captures trace outputs. TSPMON also writes the diagnostics to the current command window, which is helpful for real-time troubleshooting. TSPMON can also be enabled through Windows Terminal Services; DBMON cannot. Using DBMON DBMON must be run from a command prompt on the server console. Copy the application to your system and- just before you reproduce the problem-issue this command: dbmon.exe > dbmon.txtThis routes all tracing output from the application to a file in the same directory as dbmon.exe. After the problem has been reproduced, press Ctrl + C to stop the application. Send the dbmon.txt file to your Technical Support engineer. Using TSPMON TSPMON must be run from a command prompt on the server console. If the TSP is version 3.0(3) or 3.0 (4), set HKLM\Software\Active Voice\AvSkinny\LogMgr Enabled = 0 in the registry and restart Cisco Unity before you use TSPMON. Copy the application to your system and-just before you reproduce the problem-issue this command: tspmonThis routes all tracing output from the application to a file called tspmon.log in the same directory as tspmon.exe. After the problem has been reproduced, press X to stop the application. Do not use Ctrl + C, or you lose the last few lines of diagnostics. Send the tspmon.log file to your Technical Support engineer. http:// www.cisco.com/en/US/partner/products/sw/voicesw/ps2237/products_tech_note09186a0080094c53.shtm l#setskinny

What command can you use to check the fans for proper operation in a Cisco ICS 7750?
A. show fan
B. check fan
C. get fan-speed
D. show fan-speed
Correct Answer: C Section: (none) Explanation
Explanation/Reference:
Checking Fan Speed and Operation The SAP on the CiscoICS7750 monitors the operational status of each component in the system. Working with the Fault Management Module (FMM) and ICS System Manager, the SAP can remotely alert you of environmental, functional, or operational problems detected within the system. Access is available through the console port on the front of the card. One element of the CiscoICS7750 that can affect performance is the speed of its fans. The fans run at different speeds, depending on the system’s operation:
1.
At power up, the fans should run at high speed (high noise level) for up to 10seconds. After that time, they should go into normal operation mode.
2.
At normal operation, the fans should be spinning at a low speed (low noise level).
3.
During a software upgrade, the fans should run quietly.
4.
Following a software upgrade, the fans should run as they do during the power-up process, spinning fast for about 10 seconds and then slowing down to normal operation. Follow these steps to check the fans for proper operation: Step1 On a PC, open a HyperTerminal session with the SAP card. Step 2 At the prompt, enter enable mode by typing slpenablepassword, followed by the password for the card. Step 3 Enter the following command: getfan-speed :<fan#> where fan# is the number of the fan that you wish to check. The following is an example of output that shows fans running at normal operation: AlarmCard>get fan-speed :1 INF FAN-SPEED : 1, 2250 AlarmCard>get fan-speed :2 INF FAN-SPEED : 2, 2250 AlarmCard>get fan-speed :3 INF FAN-SPEED : 3, 2250 AlarmCard>get fan-speed :4 INF FAN-SPEED : 4, 2280

Cisco Unity.
What can you use as a filter to ensure that you receive only Unity events?
A. _MC
B. _Unity
C. _AVVID
D. _Activevoice
Correct Answer: A Section: (none) Explanation
Explanation/Reference:
Event Notification Utility The Event Notification utility sends e-mail, voice mail, or both to subscribers or public distribution lists in response to an error condition or potential problem on the CiscoUnity server. The utility monitors the Windows application log and sends notification when a specified event occurs, such as “Disk almost full.” In addition, the utility can also automatically restart the CiscoUnity server when a specified event occurs. The Event Notification utility has several default event notifications predefined, though some event notifications, such as those which require the CiscoUnity server to automatically restart, are disabled. The notification settings for the default event notifications specify that an e-mail is sent to the System Event Messages distribution list. Because the Example Administrator is the only member of this distribution list by default, assign the appropriate subscriber(s) or public distribution list to the list to ensure that someone receives event notifications. You can disable or enable existing event notifications, as well as modify the event which is monitored, how you are notified when the event occurs, and who receives notification. You can also add new event notifications. There are two types of event notifications that you can create:
Type Action
NT Event Log The utility notifies you when an
application event that you specify
occurs.
Reboot CiscoUnity The utility notifies you and automatically restarts CiscoUnity when an application event that you specify
occurs.
Note that CiscoUnity writes events only to the Windows application log; it does not write events to the system or security logs. To generate an Event Log report for all application events on the CiscoUnity server, or for the events that apply only to CiscoUnity, see the “Event Log Report” section. You can also view application events by using the Windows Event Viewer (from the Start menu, click Programs > Administrative Tools > Event Viewer). You can identify the CiscoUnity events in either the Event Log report or the Event Viewer as those events that end in “_MC” (for example, “AvLogMgrSvr_MC”). For more information on Windows events, refer to the Windows Event Viewer online Help.

Usage Guidelines You can configure one or two backup CiscoCallManager servers. The list of IP addresses or DNS names is an ordered and prioritized list. The CiscoCallManager server that was defined with the mgcp call-agent command has the highest priority (that is, it is the primary CiscoCallManager server). The gateway selects a CiscoCallManager server on the basis of the order of its appearance in this list. Examples In the following example, the IP address of the backup CiscoCallManager is 10.0.0.50: ccm-manager redundant-host 10.0.0.50 http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122tcr/122tvr/ vrg_c2.htm#wp1095
QUESTION 106
You have recently installed IP Phones on a centralized model. At a remote branch using a H.323 gateway, users are complaining they cannot call some internal numbers. After dialing the last digit, they get a
reorder tone.
What is the most likely cause?
A. Partition/CSS configuration issue
B. Gateway dial-peer configuration issue
C. Codec mismatch
D. Call Admission Control
Correct Answer: D Section: (none) Explanation
Explanation/Reference:
In centralized processing environment, the locations feature in Cisco CallManager lets you specify the maximum amount of audio bandwidth (for audio calls) that is available for calls to and from each location. This limits the number of active calls and limits oversubscription of the bandwidth on the IP WAN links. If any additional calls try to exceed the bandwidth limit, the system rejects them, the calling party receives reorder tone, and a text message displays on the phone.
