Cisco® Smart Call Home is an automated support capability that provides continuous monitoring, proactive diagnostics, alerts, and remediation recommendations on your Cisco device. Smart Call Home can help identify and resolve issues quickly to achieve higher network availability and increased operational efficiency.

Your Cisco device can send Call Home messages using one of the following transport methods:

• E-mail directly from your device to Cisco, via a local mail server
• HTTPS directly from your device to Cisco

When enabled, Smart Call Home looks for a specific set of faults that Cisco has identified through interaction with Cisco Technical Assistance Center (TAC) engineers, the Cisco support community, and developers. When a significant event is detected, it is reported to Cisco IT through the Smart Call Home system, which compares the alerts to an extensive set of rules based on Cisco's intellectual capital. These rules determine when the problem occurred and on what device in the network, the potential impact of the failure, and the analysis and recommended steps to remediate the problem. You receive notification of these alerts and events, via email or to a specified web portal. These emails contain links to the Smart Call Home web application, or portal, as well as links to the Cisco TAC case if one was automatically created.

1. Choose Administration > Smart Call Home.
2. Choose the Call Home Service as enabled. This allows you to use Smart Call Home on your device.

A profile provides a structure to select transport methods and multiple destination addresses, and to subscribe to alerts to send periodic configuration and inventory messages. Your device contains a default profile called CiscoTAC-1 that is pre-configured for use with Smart Call Home. Although you can update most sections of the default profile, you cannot change alert group subscriptions. To configure different alert groups or transport modes to suit your requirements, you can configure custom smart call home profiles.

The CiscoTAC-1 profile is configured to use the following transport mode settings:

Note: You cannot enable both Email and HTTP/HTTPS transport modes at the same time, in the default profile.

• Email Smart Call Home email callhome@cisco.com - By default, the Email transport mode is chosen in the CiscoTAC-1 profile. This instructs your device to send raw messages and diagnostics to Cisco via email to callhome@cisco.com. This does not determine who receives email notifications from Smart Call Home. By default, the contact email address specified during configuration will receive email notifications. To configure additional recipients, add the email addresses in the Address field and click +.
• HTTPS address http://tools.cisco.com/its/service/oddce/services/DDCEService- The HTTP/HTTPS transport mode uploads all Smart Call Home notification to http://tools.cisco.com/its/service/oddce/services/DDCEService. Ensure that you have configured a certificate authorities (CA) trustpoint on your device. For more information on CA trustpoints, see About CA Trustpoints.

Updating the Default CiscoTAC-1 Profile

On the Administration > Smart Call Home page, choose the default profile CisoTAC-1. Details of the profile are displayed in the Smart Call Home Details page. Update transport modes, wireless events and advanced profile settings. Click Update & Apply to Device.

Configuring Global Parameters

On the Administration > Smart Call Home page and Global Parameters section, click Configure. The Global Settings window is displayed. Enter contact information, configure transport modes, advanced profile settings, and wireless events.

Note: General settings are applicable to CiscoTAC-1 and all the custom profiles on your device.

1. On the General tab, enter the email address at which Cisco Technical Assistance (Cisco TAC) can contact your organization. This information is required.
2. Optionally, enter your telephone and address information, your customer ID, contract ID, and site ID. This information is only used in the XML header of the Call-Home message and is not required by the Smart Call Home System.
3. You can specify a source interface name or source IP address, and a virtual routing and forwarding (VRF) interface to send Smart Call Home notifications. You can enter a source IP address, or specify a source interface name, not both.
4. If you choose email as the transport mode for your notifications, you must configure a mail server for your e-mail. In the Mail Server field, Click + icon. Use the Move Up and Move Down buttons to assign a priority to each server. The priority you assign here determines which server is used as the active server, and which servers are used during failure. The priority numbers range from the highest priority of 1 to the lowest priority of 100. The server with the highest priority, which the device is able to establish a connection with becomes the active email server.
5. In the Sender Email field, specify the email address that you want displayed in the From field in the Smart Call Home email notifications sent to you.
6. In the Recipient Email field, specify the email address that you want displayed in the Reply-To field in the smart call home email notifications sent to you. If the reply-to recipient's email address is not configured, the address provided in the Contact Email-Address field, is used as the sender’s reply-to email address in all notification messages.
7. Click Save & Apply to Device.

Note: Advanced settings are applicable to CiscoTAC-1 and all the custom profiles on your device.

1. On the Advanced tab, select the Syslog Throttling check box to prevent your device from sending repetitive syslog messages.
2. From the Level drop-down list, choose the privacy level to scrub data from Smart Call Home messages to protect your privacy. The default data-privacy level is Normal. Setting the privacy level to High scrubs data such as the IP address and IP domain name from the messages.
3. Select the Remove Host Name check box to remove the host name from the subject line of the Smart Call Home notification email that is sent.
4. To enable AAA authorization for Smart Call Home messages, select the Authorization Status check box. Specify the user name for authorization. The default user name is callhome.
5. Click Save & Apply to Device.

You can specify the wireless events that should trigger Smart Call Home notifications. By default, for an AP crash event, notifications are already enabled.

1. On the Events tab, select the Client Failure check box to monitor authentication and roaming failures associated with wireless clients. Smart Call Home detects both AAA failures and Roaming (authentication and mobility) failures, and sends a notification when the number of failed attempts exceeds the set threshold.
2. Set the Client Join Failure threshold or the percentage of failed client-join attempts within the specified time interval, at which to send notifications.
3. Set the Client Roam Failure threshold or the percentage of failed roaming attempts within the specified time interval, at which to send notifications.
4. Specify the interval or the time period, in minutes, during which to measure client join failures.
5. Select the RRM Threshold check box to monitor power fluctuations based on Radio Resource Management (RRM) metrics, and channel fluctuations based on Dynamic Channel Assignment (DCA). Smart Call Home sends notifications when the power change measured over a specified period interval, exceeds the set threshold. You can configure RRM events for both 2.5 GHz and 5 GHz radios.
6. In the Channel Change field, set the threshold or the number of channel changes after which to send Smart Call Home notifications.
7. In the Power Change Upper and Power Change Lower fields, assign the upper and lower threshold between 3 to 30 dBm. The default is 6 dBm.
8. Set the time interval, between 1 and 1440 minutes, during which to measure power and channel change events. The default is 60 minutes.
9. Click Save & Apply to Device.

On the Administration > Smart Call Home page and Profile Settings section, click Add. The Add Profile window is displayed.

Note: You must specify at least one transport mode, in the custom profile.

1. On the Profile tab, specify a name for the new profile.
2. To apply the profile to your device, set the Status button to Active. Multiple profiles can be active on your device.
3. Choose a transport mode to determine how Smart Call Home notifications should be delivered to you.
4. Choose Email, to receive Smart Call Home notifications via email. In the Address field, specify the email address to which to send notifications, and click +. You can add multiple email addresses. If you choose Email, specify at least one email address, and ensure that you configure a mail server for your email.
5. Choose HTTP/HTTPS, to send Smart Call Home notifications to a specified portal or website. Specify the location to which you want to send notifications, in the URL field and click +. If you choose HTTP/HTTPS, the HTTP URL is required. If you provide an HTTPS location as the URL, ensure that you have configured a certificate authorities (CA) trustpoint on your device. For more information on CA trustpoints, see About CA Trustpoints.
6. Optionally, you can set an HTTP/HTTPS proxy server using which notifications can be sent.
7. Click Save & Apply to Device.

To make monitoring easy, you can configure Smart Call Home to detect alerts of a specific category.

1. On the Alerts tab, choose the alert group to which you want to subscribe. When an event occurs in the alert group that you subscribed to, your device is monitored to obtain more information about the event, at the time of the event, and the output is included in the Smart Call Home message that is sent to Cisco and other configured recipients.
2. You can subscribe to multiple alert groups. To subscribe to Syslog and Crash alert groups, and set the same severity level for all the alerts, select All. From the Severity drop-down list, choose the severity threshold based on which to filter messages in the alert group.
3. To subscribe to only one, or a few of the Smart Call Home alert groups, select the check box for the alert group you want. From the Severity drop-down list, choose the severity threshold based on which to filter messages in the alert group.
4. When you subscribe to the Syslog alert group, you can optionally specify a text pattern to be matched within each syslog message. Click + to add a design pattern. If you configure a pattern, a Syslog alert group message is sent only if it contains the specified pattern and meets the severity threshold.
5. When you subscribe to the Configuration, Inventory, and Snapshot alert groups, you can choose to receive the alert group messages asynchronously or periodically at a specified time. For the Snapshot alert group, you can only choose to receive the alert group messages periodically. You can configure the time when alerts are sent, in the following way:
   • Daily—Specify the time of day, using an hour:minute format hh:mm, with a 24-hour clock (for example, 14:30). 
   • Monthly—Specify the numeric date, from 1 to 31, and the time of day, in the format date hh:mm.
   • Weekly—Specify the day of the week and time of day in the format day hh:mm, where the day of the week is spelled out (for example, Monday).

6. As part of the snapshot, you can periodically record command line interface (CLI) command output. The output is included in the smart call home notification sent to you.
