•
To fix the problem:
Wait a few minutes, then refresh the page that you are viewing.
Can I change the tcp port that ITM uses to connect to Cisco CallManager for http?
No. ITM uses port 80.
Why do I need to provide a privileged (CCM Admin) username and password for ITM to monitor Cisco CallManager?
ITM requires read-only access to Cisco CallManager HTTP interfaces to get cluster-level connectivity information. Beginning with IDU 2, ITM supports Cisco CallManager 4.0 with multilevel administration access (MLA).

Why does a device remain in Learning state?
User Guide for IP Telephony Monitor provides many tips to help you determine why a device stays in the Learning state and how to move a device out of the Learning state. The tips are located at the end of the "Adding a Device" procedure.
Can I delete a device that is in Pending state?
No. To move the device out of Pending, try initiating rediscovery of the device manually.
Device Discovery
How can I check whether discovery ran?
Can I use ITM Multi-View to create rediscovery schedules that apply to individual partitions?
I added two rediscovery schedules. Why does only one rediscovery schedule run?
Why doesn't the schedule that I added appear on Rediscovery Schedule page?
How can I check whether discovery ran?
Check the status and time of the last rediscovery schedule on the Job Manager page by selecting Server Configuration > Administration > Job Management.
Can I use ITM Multi-View to create rediscovery schedules that apply to individual partitions?
No. ITM Multi-View rediscovery schedules apply to all partitions. ITM Multi-View rediscovers all devices, regardless of partition.
I added two rediscovery schedules. Why does only one rediscovery schedule run?
This can occur because rediscovery schedules are too close together.
Note
To fix the problem, update rediscovery schedules to start more than 5 minutes apart.
Why doesn't the schedule that I added appear on Rediscovery Schedule page?
There might be a problem with the job manager:

Alerts and Notifications
The following topics contain questions about alerts, details for devices with alerts, fault history, and notifications.
Alerts and Activities
How is the Alerts and Activities display information organized?
When I click an event, I see the value of MIB properties. What time do they reflect?
Why are cleared events still listed on the Alerts and Activities display?
Why isn't ITM reporting a fault on a device?
Why do I see alerts with a duration of 999 hours?
Why is the alert still active when I know the underlying problem with the device is fixed?
Does ITM monitor B channels of BRIs/PRIs?
Why do I see false operationally down alerts on D Channels?
How do I suspend monitoring for an interface?
How can I disable events for backup interfaces?
Why does ITM generate an ApplicationDown event for IP telephony application that I have disabled?
How can I stop alerts for an IP telephony application that I have disabled?
When is the CCMHttpServiceInaccessible event supported?
What causes an event to show up as an Unidentified Trap?
How is the Alerts and Activities display information organized?
By severity, with last change listed first.
What do the diamonds mean?
Diamonds indicate how recently activity occurred on each alert. Alerts with more diamonds (up to a maximum of 3) have more recently experienced activity. Alerts are based on events. Alert activity is noted when events are updated—for example, new events occur or existing events are acknowledged.
Within last 15 minutes
Within last 16-30 minutes
Within last 31-45 minutes
No diamonds

When I click an event, I see the value of MIB properties. What time do they reflect?
The time the event first occurred. The only time the MIB values shown change is after the event cleared but reoccurred.
Why are cleared events still listed on the Alerts and Activities display?
Because the event was rolled up into an alert, and some other event in the alert is still occurring. Once the entire alert is cleared, it is removed from the Alerts and Activities display.
We know there is a fault on this device. Why doesn't it show up on the Alerts and Activities display?
This could happen when the device:
•
•
•
•
To solve this problem:
•
•
•
•
Why isn't ITM reporting a fault on a device?
For one of these reasons:
•
•
•
•
Why do I see alerts with a duration of 999 hours?
The duration of an alert is calculated as the difference between the current server time and the start time for the earliest event that triggered the alert, whether or not that event is still active.
After an alert is active for more than 999 hours, the Alerts and Activities display shows a duration of 999 hours as long as any event for that alert remains active.
Why is the alert still active when I know the underlying problem with the device is fixed?
An alert remains active until all events for the device are cleared.
•
•
What is a view?
A view is a collection of one or more devices that you want to monitor using the Alerts and Activities display. A view is:

Does ITM monitor B channels of BRIs/PRIs?
No. However, ITM monitors D channels.
How can I stop BackupActivated events from being generated when B Channels on a voice T1 are activated?
Suspend monitoring of backup interfaces for devices as they present alerts. Doing so suppresses the BackupActivated event for that device.
Why do I see false operationally down alerts on D Channels?
D Channel status cannot be obtained if the D Channels are intentionally kept down. If the D Channels are intentionally kept down, suspend monitoring of the corresponding D Channel interfaces through the Detailed Device View page.
How do I suspend monitoring for an interface?

Can I see a Detailed Device View for a device without alerts against it?
No.
Why does the Detailed Device View show blank registration status for Cisco CallManager-related devices?
This problem can occur when the media server or ICS with the Cisco CallManager that the devices are registered to was not added to ITM.
To fix the problem:
Add the media server or ICS to ITM.
For ITM Multi-View only: Move the newly added device to the partition with the devices that show no registration status.
Why does Detailed Device View show registration status NotFound for Cisco CallManager-related devices?
There could be a problem with Internet Information Service on the media server where Cisco CallManager runs.
Why can't I find details for a voice gateway with registration rejected by Cisco CallManager?

•
To resolve this problem, configure Cisco CallManager to forward CiscoCallManagerGatewayFailed trap to ITM.
Fault History
When I click an Alert ID in a Fault History display, why do I get a message about annotations?
When I click an Alert ID in a Fault History display, why aren't event details displayed?After you click an Alert ID on a Fault History Alerts and Activities display, ITM should display a popup window with annotations for the alert. If no annotations exist, ITM should display a message: There is no annotation for alert ID=<xxxxxxx>
To see event details for an alert, open a Fault History: Events display. (Start by selecting Fault History >Event Filtering.)
Notification Services
Why are there no notifications for devices I just added to ITM?
There's an alert on a device. Why wasn't a trap notification received?
Why are there no notifications for devices I just added to ITM?
Adding a new device to ITM does not update existing e-mail or trap notification subscriptions.
To fix the problem, edit an existing subscription or create a new one to generate notifications for newly added devices.
There's an alert on a device. Why wasn't a trap notification received?

IP Phones—Information and Tests
The following topics contain questions about gathering and viewing IP phone information, monitoring phone reachability, and monitoring SRST status of phones.
•
IP Phones—General Questions
How can I monitor key phones after installing IDU 2 or later?
Should I import phones?
No, not with IDU 2 and later. With IDU 2 and later:
•
•
How can I monitor key phones after installing IDU 2 or later?
Use IP Phone Reachability Testing.
IP Phone Information Facility
Which devices must ITM monitor before major phone discovery can find phones?
How can I suspend major phone discovery?
How often does minor phone discovery run?
What information does minor phone discovery track?
How does phone discovery handle phones connected to trunk ports?
Which devices must ITM monitor before major phone discovery can find phones?
•
•
How can I suspend major phone discovery?
Delete all phone discovery schedules. (To resume major phone discovery, add a phone discovery schedule.)
How often does minor phone discovery run?
Every 5 minutes.
What information does minor phone discovery track?
Changes to the phone: phone moves and audit details (phones added, deleted, registered, unregistered).
How does phone discovery handle phones connected to trunk ports?
Phone discovery does not discover phones connected to trunk ports. An exception is made for Cisco Catalyst 3500 series switches, because voice-vlan configuration is not supported and configuration guidelines for these switches recommend trunk mode.
Why is switch, VLAN, and port information for Cisco Catalyst 3550 Series switches missing from Phone Details and Phone Audit Details?
The configuration guide for Cisco Catalyst 3550 Series switches specifies that ports to which IP phones are connected should be in access mode. IP Information Facility supports IP phones connected to ports in access mode. Check whether the ports to which the IP phones are connected are in trunk mode.
IP Phone Reachability
Note
Can I get some help creating a seed file for IP Phone Reachability tests?
What devices must ITM monitor to enable IP Phone Reachability testing?
Can IP Phone Reachability use information from IP Phone Information Facility at all?
Can I get some help creating a seed file for IP Phone Reachability tests?
You can export information for all phones and edit it as follows:
1.
2.
3.
–
–
What devices must ITM monitor to enable IP Phone Reachability testing?
None.
Can IP Phone Reachability use information from IP Phone Information Facility at all?
Yes. If Cisco CallManager and phone access switches are known to ITM, IP Phone Reachability updates phone extensions and IP addresses in phone reachability tests using information from IP Phone Information Facility.
SRST Management
Note
Why are some SRST phones missing from IP Phone Information Facility displays?
Why did the SRST test status change from Active to Suspended?
Why did an SRST test "disappear" from the SRST Operations page?
Why are some SRST phones missing from IP Phone Information Facility displays?
•
•
The WAN link is up and all phones in the branch office are unregistered with the central Cisco CallManager. Why don't I see an SRSTSuspected event?
ITM generates an SRSTSuspected event only after all SRST phones remain unregistered for 2 minor discovery cycles.
Why did the SRST test status change from Active to Suspended?
The source or target router might be suspended from ITM monitoring. (Check whether the router is suspended on the Suspended Devices view of the Alerts and Activities display.)
Note
Why did an SRST test "disappear" from the SRST Operations page?
•
•
IP Phone Information Facility already displays a the new extension for an SRST phone. Why isn't SRST information available for it?
ITM tracks SRST information only for the IP phone MAC addresses and extensions that you supply in a seed file. If you change MAC addresses and extensions, you should update the seed file and reimport SRST information.

A group from which you create a subgroup. Device groups are subsets (children) of larger groups (parents).
Why are some devices that match the rule for my User Defined Group not included as members?
The device matches the rules for the immediate group, but not for the parent group.
Why isn't a device I added to ITM showing up in the expected User Defined Group?
One of the following:
•
•
What are Customizable Groups?

•
How do I configure a Customizable Group so that it includes only those devices actually configured with backup interfaces?
1.
2.
To maintain this group, edit it after you add or remove devices with backup interfaces to ITM.
How can I create a Customizable Group that will automatically include new devices added to ITM?
Edit a customizable group to set Membership Update to Automatic.
Can I group devices by interface type or description?
Yes. Create user-defined groups using rules that include the following object types and attributes:
•
•
Note
Where is the Cisco CallManager or Cluster group for a media server I moved into a partition?
Note
The cluster group for this media server might exist in another partition. This happens if other media servers belonging to this cluster were already moved to the other partition.
Check NMSROOT/log/ItemLogs/VHM/ciscocallmanagerorclustergrouping.log. If the media server exists in a different partition, move all media servers belonging to this cluster to the desired partition.
Why is a device that is logically connected to a Cisco CallManager not displayed under the appropriate cluster group?
The device is not registered to the cluster.

Polling and Thresholds
Which polling and threshold settings are applied to a particular device?
How are device groups prioritized for Polling and Thresholds?
Can I modify device group priority for Polling and Thresholds?
How many groups can a device belong to?
Why do I need to perform Apply Changes?
When do I need to perform Apply Changes?
Why is a particular device not being polled?
Which User Defined Groups can I use for setting polling and threshold parameters?
Why is application and connectivity polling not happening?
How can I set timeout and retry values for Application polling settings for media server and ICS?
How should I set the Confidence Test Tolerance Threshold?
Which polling and threshold settings are applied to a particular device?
A device takes the settings of the highest priority group (called Overriding Group) to which it belongs. You can view the overriding group for a device on either of the following displays:
•
•
How are device groups prioritized for Polling and Thresholds?
Customizable Groups have a higher priority than System Defined Groups.
System Defined Groups in priority order from highest to lowest are:
•
•
•
•
•
•
•
•
•
•
•
•
•
•
Can I modify device group priority for Polling and Thresholds?
No. You cannot modify the priority of System Defined Groups. However, you can modify the priority of Customizable Groups.
How many groups can a device belong to?
A device belongs to at least one group and can belong to multiple groups, depending on the device's function in ITM.
What is an Overriding Group?
The highest priority group to which a device belongs. The priority determines which polling and threshold settings are applied to a device.
Why do I need to perform Apply Changes?
Otherwise, your changes to polling settings and thresholds do not take effect.
When do I need to perform Apply Changes?
After you change polling settings and thresholds for all groups that you want to change at one time, apply changes by selecting IP Telephony Monitor > Configuration > Apply Changes. (It is a CPU-intensive operation.)
Note
Why is a particular device not being polled?
This problem could be caused by any of the following:
•
•

Why aren't all groups that I see on Group Management pages displayed on Polling and Thresholds pages?
Polling and thresholds pages do not display device groups unless they contain members.
Which User Defined Groups can I use for setting polling and threshold parameters?
Customizable Groups (only).
Digital Voice Gateway and Monitored Phone device groups have members. Why aren't those device groups on Polling and Thresholds application pages?
No polling or threshold settings are associated with these groups. Therefore, they are not displayed on Polling and Thresholds pages.
Why is application and connectivity polling not happening?
Application and connectivity polling processes do not start until:
•
•
Changes are not in effect for some devices in this group even after I modified settings in Polling and Thresholds. Why?
This occurs for one of the following reasons:
•
•
To fix this problem:
•
•
How can I set timeout and retry values for Application polling settings for media server and ICS?
You cannot set these values on the Polling Parameters: Edit page because ITM uses the global SNMP timeout and retry values for media server and ICS. Change global SNMP timeout and retry values as follows:
1.
2.
3.
Note
Why is connectivity to the cluster not polled for Cisco CallManager, Cisco gateway, or Cisco gatekeeper?
For ITM Multi-View users only.
Media server or ICS with Cisco CallManager was not added to the same partition as the voice gateway, digital voice gateway, or gatekeeper.
To fix the problem:
1.
2.
How should I set the Confidence Test Tolerance Threshold?
ITM applies the Confidence Test Tolerance threshold to a sample size of four tests. When the percentage of actual failures exceeds the threshold value, ITM generates a TooManyFailedConfidenceTests event.
SNMP Traps

Does ITM report all SNMP traps?
No. ITM processes certain traps that are relevant to the operational health of IP telephony. See the Processed and Pass-through Traps, and Unidentified Traps and the Events appendixes in User Guide for IP Telephony Monitor.
How does ITM handle SNMP traps?
For certain SNMP traps, ITM will either:
•
•
For more information, see the Processed and Pass-through Traps, and Unidentified Traps and the Events appendixes in User Guide for IP Telephony Monitor.
What version of SNMP traps does ITM support?
ITM supports SNMP V1 and SNMP V2 traps for polling and receiving. Received V2 traps are forwarded as V1 traps.
How do I configure ITM to receive traps?
ITM is already configured to receive SNMP traps, but you can specify a different listening port by updating the SNMP Trap Receiver. For more information, see the "Configuring SNMP Trap Receiving and Forwarding" topic in User Guide for IP Telephony Monitor.
How do I configure ITM to forward traps?
You can use SNMP Trap Forwarding to configure ITM to forward unprocessed traps. For more information, see the "Configuring SNMP Trap Receiving and Forwarding" topic in User Guide for IP Telephony Monitor.
What types of generated traps does ITM send?
ITM generates one type of external SNMP trap, ciscoEpmNotificationAlarm, using the trap structure defined in CISCO-EPM-NOTIFICATION-MIB.
ITM can generate SNMP traps for all alerts that ITM generates. For information on how ITM generates alerts and events, see the Processed and Pass-through Traps, and Unidentified Traps and the Events appendixes in User Guide for IP Telephony Monitor.
Can I customize values in ITM-generated SNMP traps?
No. You will be able update some values with a future IDU.
