The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter describes how to configure SNMP and MIB support for the Cisco ASR 1000 Series Routers. It includes the following sections:
Follow these steps to determine which MIBs are included in the Cisco IOS release running on the Cisco ASR 1000 Series Routers:
Step 1 Go to the Cisco MIBs Support page:
http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml
Step 2 Under Cisco Access Products, select Cisco ASR1000 to display a list of MIBs supported on the Cisco ASR 1000 Series Routers.
Step 3 Scroll through the list to find the release you are interested in.
The following sections provide information about how to download and compile MIBs for the
Cisco ASR 1000 Series Routers:
While working with MIBs, consider the following:
This example is considered to be a trivial error and the MIB loads successfully with a warning message.
The following example is considered as a nontrivial error (even though the two definitions are essentially equivalent), and the MIB is not successfully parsed:
If your MIB compiler treats these as errors, or you want to delete the warning messages, edit one of the MIBs that defines this same datatype so that the definitions match.

Follow these steps to download the MIBs onto your system if they are not already there:
Step 1 Review the considerations in the “Considerations for Working with MIBs” section.
Step 2 Go to one of the following Cisco URLs. If the MIB you want to download is not there, try the other URL; otherwise, go to one of the URLs in Step 5 .
ftp://ftp.cisco.com/pub/mibs/v2
ftp://ftp.cisco.com/pub/mibs/v1
Step 3 Click the link for a MIB to download that MIB to your system.
Step 4 Select File > Save or File > Save As to save the MIB on your system.
Step 5 You can download industry-standard MIBs from the following URLs:
If you plan to integrate the Cisco ASR 1000 Series Routers with an SNMP-based management application, then you must also compile the MIBs for that platform. For example, if you are running HP OpenView on a UNIX operating system, you must compile Cisco ASR 1000 Series Routers MIBs with the HP OpenView Network Management System (NMS). For instructions, see the NMS documentation.
The following procedure summarizes how to configure the Cisco ASR 1000 Series Routers for SNMP support.
For detailed information about SNMP commands, see the following Cisco documents:
http://www.cisco.com/en/US/docs/ios/12_2/configfun/configuration/guide/fcf017.html
http://www.cisco.com/en/US/docs/ios/12_2/configfun/command/reference/frf017.html
To configure the Cisco ASR 1000 Series Routers for SNMP support, follow these steps:
Step 1 Set up your basic SNMP configuration through the command-line interface (CLI) on the router. Note that these basic configuration commands are issued for SNMPv2c. For SNMPv3, you must also set up SNMP users and groups. (See the preceding list of documents for command and setup information.)
a. Define SNMP based read-only and read-write communities:
b. Configure SNMP views (to limit the range of objects accessible to different SNMP user groups):
Step 2 Identify (by IP address) the host to receive SNMP notifications from the router:
Step 3 Configure the router to generate notifications. You can use keywords to limit the number and types of messages generated.
