Which web-based tool is used to access Cisco Unified Communications Manager CDR Analysis and Reporting?
A. Cisco Unified CDR Administration
B. Cisco Unified CM Administration
C. Cisco Unified Reporting
D. Cisco Unified Serviceability
Correct Answer: D Section: CUCM Explanation
Cisco Unified Serviceability
Administrators can use the Cisco Unified Serviceability web-based tool to troubleshoot problems with the Cisco Unified Communications Manager system. Cisco Unified Serviceability provides the following services:
Saves Cisco CallManager services alarms and events for troubleshooting and provides alarm message definitions.
Saves Cisco CallManager services trace information to various log files for troubleshooting. Administrators can configure, collect, and view trace information.
Monitors real-time behavior of the components in a Cisco Unified Communications Manager system.
Generates reports for Quality of Service, traffic, and billing information through Cisco CDR Analysis and Reporting (CAR) application.
Provides feature services that you can activate, deactivate, and view through the Service Activation window.
Provides an interface for starting and stopping feature and network services.
Archives reports that are associated with Cisco Unified Serviceability tools.
Allows Cisco Unified Communications Manager to work as a managed device for SNMP remote management and troubleshooting.
Monitors the disk usage of the log partition on a server (or all servers in the cluster).
To access Serviceability from the Cisco Unified Communications Manager Administration window, choose Cisco Unified Serviceability from the Navigation drop-down list box that displays in the upper, right corner of the window and click Go.
For more information, refer to the Cisco Unified Serviceability Administration Guide.
When generating QoS reports in the CAR tool, what two parameters are valid for report generation? (Choose two.)
A. route lists
B. route patterns/hunt pilots
C. route groups
D. gateway types
F. IP phone directory numbers
Correct Answer: BD Section: QoS Explanation
Configuring Route Pattern and Hunt Pilot Device Reports
Only CAR administrators generate the Route/Hunt List Utilization report. The Route/Hunt List Utilization report provides an estimate of the maximum utilization percentage of the route/hunt list (cumulative utilization of all the gateways under the route/hunt list) for the period and not the exact utilization. The system calculates the cumulative utilization of all the gateways under the route lists and all the lines under the hunt lists.
You can examine the usage based on each hour of a day or on a specified number of days for each week or month. Reports generate for each of the selected route/hunt lists.
You can either view reports that the system automatically generates or generate new reports. Only CAR administrators can schedule reports for automatic generation.
Configuring QoS System Reports
CAR provides reporting capabilities for three levels of users:
AdministratorsGenerate system reports to help with load balancing, system performance, and troubleshooting.
ManagersGenerate reports for users, departments, and QoS to help with call monitoring for budgeting or security purposes and for determining the voice quality of the calls.
Individual usersGenerate a billing report for calls by each user.
Refer to the exhibit. The user of IP phone A has opened a trouble ticket stating that he cannot call IP phone
B. Where is the best place to start troubleshooting this issue?
A. IP phone B
B. the Cisco Unified Communication Manager system in site A
C. IP phone A
D. lP phone A user
E. the local VoIP voice gateway of IP phone B
F. IP phone B user
Correct Answer: D Section: IP Phone Explanation Explanation/Reference:
Always start with the user as he/she could be doing something wrong, i.e. pressing the wrong key sequence.
Which three characteristics are associated with data?
B. TCP retransmits
C. UDP priority
D. delay sensitive
E. drop insensitive
G. benign or greedy.
Correct Answer: BEG Section: QoS Explanation
Data traffic always acknowledge TCP packets for confirm delivery E2E. It is not drop sensitive because its not real time traffic.
Which command is useful to see if network layer information is being received at a PSTN gateway?
A. show gateway status
B. show isdn q931
C. show ccm-manager status
D. show isdn status
E. show isdn q921
Correct Answer: D Section: QoS Explanation
Using the show isdn status Command
The show isdn status command displays a summary of all ISDN interfaces. It also displays the status of Layers 1, 2, and 3. Complete the following steps to check the status of the layers:
Verify that Layer 1 is in the ACTIVE state. The status of Layer 1 should always be ACTIVE unless the E1 is down.
If the show isdn status command output indicates that Layer 1 is DEACTIVATED, then there is a problem with the physical connectivity of the E1 line. If the line is administratively down, use theno shutdown command to restart the interface.
Ensure that Layer 2 is in the MULTIPLE_FRAME_ESTABLISHED state. This is the desired state for Layer 2, indicating that Layer 2 frames are being exchanged and Layer 2 initialization has finished.
If Layer 2 is not in the MULTIPLE_FRAME_ESTABLISHED state, use the show controller e1 EXEC
command to diagnose the problem. For more information, see the E1 Alarm Troubleshooting document.
Since the show isdn status command displays a summary of the current status, it is possible that Layer 2
is bouncing up and down despite indicating a MULTIPLE_FRAME_ESTABLISHED state. Use the debug
isdn q921 command to verify that Layer 2 is stable.
Following is an example of show isdn status output:
bru-nas-03#show isdn status Global ISDN Switchtype = primary-net5 ISDN Serial0:15 interface
dsl 0, interface ISDN Switchtype = primary-net5
Layer 1 Status:
Layer 2 Status:
TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
Layer 3 Status:
5 Active Layer 3 Call(s)
Activated dsl 0 CCBs = 5
CCB:callid=7D5, sapi=0, ces=0, B-chan=9, calltype=DATA
CCB:callid=7D6, sapi=0, ces=0, B-chan=10, calltype=DATA
CCB:callid=7DA, sapi=0, ces=0, B-chan=11, calltype=DATA
CCB:callid=7DE, sapi=0, ces=0, B-chan=1, calltype=DATA
CCB:callid=7DF, sapi=0, ces=0, B-chan=2, calltype=DATA
The Free Channel Mask: 0xFFFF78FC ISDN Serial1:15 interface dsl 1, interface ISDN Switchtype = primary-net5 Layer 1 Status:
Layer 2 Status:
TEI = 0, Ces = 1, SAPI = 0, State = TEI_ASSIGNED
Layer 3 Status:
0 Active Layer 3 Call(s)
Activated dsl 1 CCBs = 0
The Free Channel Mask: 0xFFFF7FFF
Total Allocated ISDN CCBs = 5
Notice that E1 0 (whose D-channel is Serial 0:15) has Layer 1 as ACTIVE and Layer 2 as MULTIPLE_FRAME_ESTABLISHED indicating that the signaling channel is functioning correctly and is exchanging Layer 2 frames with the Telco switch. The D-channel (Serial1:15) for E1 1 has Layer 1 ACTIVE, but Layer 2 is TEI_ASSIGNED. This indicates that the PRI is not exchanging Layer 2 frames with the switch. Use the show controller e1 x command to troubleshoot. Refer to the E1 Troubleshooting flowchart for more information.
