Anonymous Reporting and Smart Call Home
The Smart Call Home feature provides personalized, e-mail-based and web-based notification to you about critical events involving your individual systems, often before you know that a critical event has occurred.
The Anonymous Reporting feature is a subfeature of the Smart Call Home feature and allows Cisco to anonymously receive minimal error and health information from the device.
This chapter describes how to use and configure Anonymous Reporting and Smart Call Home, and it includes the following sections:

Information About Anonymous Reporting and Smart Call Home
This section includes the following topics:
Information About Anonymous Reporting
You can help to improve the ASA platform by enabling Anonymous Reporting, which allows Cisco to securely receive minimal error and health information from the device. If you enable the feature, your customer identity will remain anonymous, and no identifying information will be sent.
Enabling Anonymous Reporting creates a trust point and installs a certificate. A CA certificate is required for your ASA to validate the server certificate present on the Smart Call Home web server and to form the HTTPS session so that your ASA can send messages securely. Cisco imports a certificate that is predefined in the software. If you decide to enable Anonymous Reporting, a certificate is installed on the ASA with a hardcoded trust point name: _SmartCallHome_ServerCA. When you enable Anonymous Reporting, this trust point is created, the appropriate certificate is installed, and you receive a message about this action. The certificate then appears in your configuration.
If the appropriate certificate already exists in your configuration when you enable Anonymous Reporting, no trust point is created, and no certificate is installed.
Note When you enable Anonymous Reporting, you acknowledge your consent to transfer the specified data to Cisco or to vendors operating on Cisco’s behalf (including countries outside of the U.S.).
Cisco maintains the privacy of all customers. For information about Cisco’s treatment of personal information, see the Cisco Privacy Statement at the following URL:
http://www.cisco.com/web/siteassets/legal/privacy.html
DNS Requirement
A DNS server must be configured correctly for your ASA to reach the Cisco Smart Call Home server and send messages to Cisco. Because it is possible that your ASA resides in a private network and does not have access to the public network, Cisco verifies your DNS configuration and then configures it for you, if necessary, by doing the following:
1. Performing a DNS lookup for all DNS servers configured.
2. Getting the DNS server from the DHCP server by sending DHCPINFORM messages on the highest security-level interface.
3. Using the Cisco DNS servers for lookup.
4. Randomly using a static IP addresses for tools.cisco.com.
These tasks are performed without changing the current configuration. (For example, the DNS server that was learned from DHCP will not be added to the configuration.)
If there is no DNS server configured, and your ASA cannot reach the Cisco Smart Call Home Server, Cisco generates a syslog message with the warning severity level for each Smart Call Home message that is sent to remind you to configure DNS correctly.
For information about syslog messages, see the syslog messages guide.
Anonymous Reporting and Smart Call Home Prompt
When you enter configuration mode, you receive a prompt that requests you to enable the Anonymous Reporting and Smart Call Home features according to the following guidelines:
At the prompt, you may choose [Y]es, [N]o, [A]sk later. If you choose [A]sk later, then you are reminded again in seven days or when the ASA reloads. If you continue to choose [A]sk later, the ASA prompts two more times at seven-day intervals before it assumes a [N]o response and does not ask again.
At the ASDM prompt, you can select from the following options:
- Anonymous—Enables Anonymous Reporting.
- Registered (enter an e-mail address)—Enables Smart Call Home and registers your ASA with Cisco TAC.
- Do not enable Smart Call Home—Does not enable Smart Call Home and does not ask again.
- Remind Me Later—Defers the decision. You are reminded again in seven days or whenever the ASA reloads. The ASA prompts two more times at seven-day intervals before it assumes a “Do not enable Smart Call Home response” and does not ask again.
If you did not receive the prompt, you may enable Anonymous Reporting or Smart Call Home by performing the steps in the Configuring Anonymous Reporting or the Configuring Smart Call Home.
Information About Smart Call Home
When fully configured, Smart Call Home detects issues at your site and reports them back to Cisco or through other user-defined channels (such as e-mail or directly to you), often before you know that these issues exist. Depending upon the seriousness of these problems, Cisco responds to you regarding your system configuration issues, product end-of-life announcements, security advisory issues, and so on.
In this manner, Smart Call Home offers proactive diagnostics and real-time alerts on the ASA and provides high network availability and increased operational efficiency through proactive and quick issue resolution by doing the following:
- Identifying issues quickly with continuous monitoring, real-time proactive alerts, and detailed diagnostics.
- Making you aware of potential problems through Smart Call Home notifications, in which a service request has been opened, with all diagnostic data attached.
- Resolving critical problems faster with direct, automatic access to experts in Cisco TAC.
Smart Call Home offers increased operational efficiency by providing you with the ability to do the following:
- Use staff resources more efficiently by reducing troubleshooting time.
- Generate service requests to Cisco TAC automatically (if you have a service contract), routed to the appropriate support team, which provides detailed diagnostic information that speeds problem resolution.
The Smart Call Home Portal offers quick, web-based access to required information that provides you with the ability to do the following:

Prerequisites for Smart Call Home and Anonymous Reporting
Smart Call Home and Anonymous Reporting have the following prerequisite:
- DNS must be configured. See DNS Requirement and the Configuring the DNS Server.
Guidelines and Limitations
Supported in routed and transparent firewall modes.
Supported in single mode and multiple context mode.
Additional Guidelines for Anonymous Reporting
- If an Anonymous Reporting message cannot be sent on the first try, the ASA retries two more times before dropping the message.
- Anonymous Reporting can coexist with other Smart Call Home configurations without changing the existing configuration. For example, if Smart Call Home is off before enabling Anonymous Reporting, it remains off, even after enabling Anonymous Reporting.
- If Anonymous Reporting is enabled, you cannot remove the trust point, and when Anonymous Reporting is disabled, the trust point remains. If Anonymous Reporting is disabled, you can remove the trust point, but disabling Anonymous Reporting does not cause the trust point to be removed.
- If you are using a multiple context mode configuration, the dns, interface, and trustpoint commands are in the admin context, and the call-home commands are in the system context.
Additional Guidelines for Smart Call Home
- In multiple context mode, the subscribe-to-alert-group snapshot periodic command is divided into two commands: one to obtain information from the system configuration and one to obtain information from the user context.
- The Smart Call Home back-end server can accept messages in XML format only.
- A Smart Call Home message is sent to Cisco to report important cluster events if you have enabled clustering and configured Smart Call Home to subscribe to the diagnostic alert group with a critical severity level. A Smart Call Home clustering message is sent for only the following events:
– When a unit joins the cluster
– When a unit leaves the cluster
– When a cluster unit becomes the cluster master
– When a secondary unit fails in the cluster
Each message that is sent includes the following information:
– The active cluster member count
– The output of the show cluster info command and the show cluster history command on the cluster master
Configuring Anonymous Reporting and Smart Call Home
While Anonymous Reporting is a subfeature of the Smart Call Home feature and allows Cisco to anonymously receive minimal error and health information from the device, the Smart Call Home feature provides customized support of your system health, enabling Cisco TAC to monitor your devices and open a case when there is an issue, often before you know the issue has occurred.
Generally speaking, you can have both features configured on your system at the same time, yet configuring the Smart Call Home feature provides the same functionality as Anonymous reporting, plus customized services.
This section includes the following topics:
Configuring Anonymous Reporting
To configure Anonymous Reporting and securely provide minimal error and health information to Cisco, perform the following steps:
Detailed Steps
Configuring Smart Call Home
Enabling Smart Call Home
To enable Smart Call Home and activate your call-home profile, perform the following steps:
|
||
|
||
hostname(cfg-call-home)# contact-email-addr username@example.com |
Configures the mandatory contact address. The address should be the Cisco.com ID account associated with the device. This account is the e-mail address that you used to register the ASA with Cisco on Cisco.com. |
|
|
||
|
||
hostname(cfg-call-home-profile)# destination transport-method http |
Configures the destination transport method for the smart call-home message receiver. The default destination transport method is e-mail. To configure e-mail, see Enabling Smart Call Home. |
Declaring and Authenticating a CA Trust Point
If Smart Call Home is configured to send messages to a web server through HTTPS, you need to configure the ASA to trust the certificate of the web server or the certificate of the Certificate Authority (CA) that issued the certificate. The Cisco Smart Call Home Production server certificate is issued by Verisign. The Cisco Smart Call Home Staging server certificate is issued by the Digital Signature Trust Co.
Note You should set the trust point for no client-types/no validation-usage to prevent it from being used for VPN validation.
Detailed Steps
To declare and authenticate the Cisco server security certificate and establish communication with the Cisco HTTPS server for Smart Call Home service, perform the following steps:
|
(Multiple Context Mode only) Installs the certificate in the admin context. |
|
|
Configures a trust point and prepares for certificate enrollment. Note If you use HTTP as the transport method, you must install a security certificate through a trust point, which is required for HTTPS. Find the specific certificate to install at the following URL: http://www.cisco.com/en/US/docs/switches/lan/smart_call_home/SCH31_Ch6.html#wp1035380 |
|
|
Specifies a manual cut-and-paste method of certificate enrollment. |
|
|
Authenticates the named CA. The CA name should match the trust point name specified in the crypto ca trustpoint command. At the prompt, paste the security certificate text. |
|
|
Specifies the end of the security certificate text and confirms acceptance of the entered security certificate. |
Subscribing to Alert Groups
An alert group is a predefined subset of the Smart Call Home alerts that are supported on the ASA. Different types of Smart Call Home alerts are grouped into different alert groups, depending on their type. Each alert group reports the output of certains CLIs. The supported Smart Call Home alert groups are the following:
Attributes of Alert Groups
Alert groups have the following attributes:
- Events first register with one alert group.
- A group can associate with multiple events.
- You can subscribe to specific alert groups.
- You can enable and disable specific alert groups. The default setting is enabled for all alert groups.
- The diagnostic and environment alert groups support subscription for periodic messages.
- The syslog alert group supports message ID-based subscription.
- You can configure a threshold for CPU and memory usage for the environment alert group. When a certain parameter has exceeded a predefined threshold, a message is sent. Most of the threshold values are platform-dependent and cannot be changed.
- You configure the snapshot alert group to send the output of CLIs that you specify.
Information Sent to Cisco by Alert Groups
Messages are sent to Cisco periodically and whenever the ASA reloads. These messages are categorized by alert groups.
Inventory alerts consist of output from the following commands:
- show version —Displays the ASA software version, hardware configuration, license key, and related uptime data for the device.
- show inventory— Retrieves and displays inventory information about each Cisco product that is installed in the networking device. Each product is identified by unique device information, called the UDI, which is a combination of three separate data elements: the product identifier (PID), the version identifier (VID), and the serial number (SN).
- show failover state —Displays the failover state of both units in a failover pair. The information displayed includes the primary or secondary status of the unit, the Active/Standby status of the unit, and the last reported reason for failover.
- show module —Shows information about any modules installed on the ASAs, for example, information about an AIP SSC installed on the ASA 5505 or information about an SSP installed on the ASA 5585-X, and information about an IPS SSP installed on an ASA 5585-X.
- show environment —Shows system environment information for ASA system components, such as hardware operational status for the chassis, drivers, fans, and power supplies, as well as temperature status, voltage, and CPU usage.

- show phone-proxy secure-phones count—Displays the number of phones capable of secure mode stored in the database.
- show route—Displays the routing table.
- show xlate count—Shows the number of NAT sessions (xlates).
Information About the Message Severity Threshold
When you subscribe a destination profile to certain alert groups, you can set a threshold for sending alert group messages based on the message severity level. Any message with a value lower than the destination profile’s specified threshold is not sent to the destination.
Table 49-1 shows the mapping between message severity levels and syslog severity levels.
Information About Subscription Profiles
A subscription profile allows you to associate the destination recipients with interested groups. When an event registered with a subscribed group in a profile is triggered, the message associated with the event is sent to the configured recipients. Subscription profiles have the following attributes:
- You can create and configure multiple profiles.
- A profile may configure multiple e-mail or HTTPS recipients.
- A profile may subscribe multiple groups to a specified severity level.
- A profile supports three message formats: short text, long text, and XML.
- You can enable and disable a specific profile. Profiles are disabled by default.
- You can specify the maximum message size. The default is 3 MB.
A default profile, “Cisco TAC,” has been provided. The default profile has a predefined set of groups (diagnostic, environment, inventory, configuration, and telemetry) to monitor and predefined destination e-mail and HTTPS URLs. The default profile is created automatically when you initially configure Smart Call Home. The destination e-mail is callhome@cisco.com and the destination URL is https://tools.cisco.com/its/service/oddce/services/DDCEService.
Note You cannot change the destination e-mail or the destination URL of the default profile.
When you subscribe a destination profile to the configuration, inventory, telemetry, or snapshot alert groups, you can choose to receive the alert group messages asynchronously or periodically at a specified time.
Table 49-2 maps the default alert group to its severity level subscription and period (if applicable):

Enters the profile configuration mode for the specified destination profile. If the specified destination profile does not exist, it is created. You can create a maximum of 10 active profiles. The default profile is to report back to Cisco TAC. If you want to send call home information to a different location (for example, your own server), you can configure a separate profile. |
|
ciscoasa(cfg-call-home-profile)# destination address email username@example.com ciscoasa(cfg-call-home-profile)# destination preferred-msg-format long-text |
Configures the destination, message size, message format, and transport method for the smart call-home message receiver. The default message format is XML, and the default enabled transport method is e-mail. The e-mail-address is the e-mail address of the smart call-home message receiver, which can be up to 100 characters long. By default, the maximum URL size is 5 MB. Use the short-text format to send and read a message on a mobile device, and use the long text format to send and read a message on a computer. If the message receiver is the Smart Call Home back-end server, ensure that the preferred-msg-format value is XML because the back-end server can accept messages in XML format only. The Enabling Smart Call Home specifies how to set the transport method to HTTP. You can use this command to change the transport method back to e-mail. |
