Add an SNMP Profile

Administrators can create SNMP profiles to let CA Performance Center query devices for performance data. You can create these profiles for SNMPv1/v2c, or for SNMPv3.

If no tenant definitions have been created, SNMP profiles are shared among all data sources. However, SNMP profiles are specific to each tenant. The global administrator only sees a list of SNMP profiles associated with the Default Tenant. In multi-tenant environments, each tenant administrator can only see the profiles for that tenant.

Follow these steps:

  1. Log in as a user with the Administrator role.
  2. Navigate to the Manage SNMP Profiles page.

    The Manage SNMP Profiles page displays the current list of SNMP profiles.

  3. Click New.

    The Add SNMP Profile dialog opens.

  4. Complete the fields and change any default settings as needed. Some fields apply only to SNMPv3.
    Profile Name

    Defines a name for the SNMP profile. Profile names must be unique, cannot be duplicated across SNMP versions, and are not case-sensitive.

    SNMP Version

    Specifies the version of SNMP that the profile uses. Because SNMPv1 and SNMPv2C are similar from a security standpoint, they share a single option. SNMPv3 is a separate option.

    Port

    Identifies the port that is used to make SNMP connections to devices associated with this profile.

    Note: Optional parameter for SNMPv1/v2C.

    Default: 161.

    Community Name

    (SNMPv1/v2C Only) Defines a secure string that lets the data source query the MIB of the associated device. The community that you supply must provide read-only access to the device MIB.

    Note: In the default SNMP profile, the community is 'public'.

    Verify Community Name

    Confirms the secure community string (name).

    Authentication Protocol

    Specifies the authentication protocol to use when contacting devices associated with this profile. Select one of the following algorithms for authenticating SNMPv3 packets:

    • None (do not attempt authentication)
    • MD5 (Message Digest 5)
    • SHA (Secure Hash Algorithm)
    Authentication Password

    Specifies the password for authentication using SNMPv3 and the selected authentication protocol.

    Note: Some data sources do not support authentication passwords or privacy passwords that are shorter than eight characters. For example, CA Infrastructure Management Data Aggregator data sources enforce a minimum of eight characters. Consult the Administrator Guide for the data source and if applicable, provide passphrases greater than eight characters in length. Blank passwords are not supported for SNMP v3 profiles with MD5 or SHA as the Authentication Protocol.

    Verify Authentication Password

    Confirms the authentication password.

    Privacy Protocol

    (optional) Specifies the encryption protocol to use for data flows sent to any devices or servers associated with this profile, as follows:

    • None (do not encrypt communications)
    • DES
    • AES (128-bit encryption)
    • Triple DES
    • AES 192 (192-bit encryption)
    • AES 256 (256-bit encryption)

    Note: The privacy protocol option is not enabled until authentication is enabled for this profile.

    Privacy Password

    Defines the password used when exchanging encryption keys. See the Note for a possible length requirement.

    Verify Privacy Password

    Defines the password used when exchanging encryption keys.

    Use by default for new devices

    Specifies whether the information in this profile is used by default. CA Performance Center uses this information to contact any new items that are discovered from monitored traffic. If it fails, the next profile in priority order is used. Disable this parameter to exclude a profile from discovery.

    Note: This parameter does not apply to CA Infrastructure Management Data Aggregator data sources.

  5. Click Save.
  6. You return to the Manage SNMP Profiles page. The new profile appears in the list.

    CA Performance Center automatically performs a global synchronization to send the profile information to all registered data sources.
