Cisco ASR 1000 Series Aggregation Services Routers are Cisco routers deployed as managed service provider routers, enterprise edge routers, and service provider edge routers. These routers use an innovative and powerful hardware processor technology known as the Cisco QuantumFlow Processor.

Cisco ASR 1000 Series Aggregation Services Routers run the Cisco IOS XE software and introduce a distributed software architecture that moves many operating system responsibilities out of the IOS process. In this architecture, Cisco IOS, which was previously responsible for almost all of the internal software processes, now runs as one of many Cisco IOS XE processes while allowing other Cisco IOS XE processes to share responsibility for running the router.

Important Notes

The following sections contain important notes about Cisco ASR 1000 Series Aggregation Services Routers.

Encrypted Traffic Analytics Records not Exported After Reload

When the router is reloaded with a large configuration, which generates many messages for initializing features in the data plane, Encrypted Traffic Analytics (ETA) records may not be exported. This occurs if the inactive timeout command is included in the configuration.

Workaround

Remove the inactive timeout command from the ETA configuration. After reloading the router, you can add the inactive timeout command to the configuration.

Caveats

Open and Resolved Bugs

The open and resolved bugs for a release are accessible through the Cisco Bug Search Tool. This web-based tool provides you with access to the Cisco bug tracking system, which maintains information about bugs and vulnerabilities in this product and other Cisco hardware and software products. Within the Cisco Bug Search Tool, each bug is given a unique identifier (ID) with a pattern of CSCxxNNNNN, where x is any letter (a-z) and N is any number (0-9). The bug IDs are frequently referenced in Cisco documentation, such as Security Advisories, Field Notices and other Cisco support documents. Technical Assistance Center (TAC) engineers or other Cisco staff can also provide you with the ID for a specific bug. The Cisco Bug Search Tool enables you to filter the bugs so that you only see those in which you are interested.

In addition to being able to search for a specific bug ID, or for all bugs in a product and release, you can filter the open and/or resolved bugs by one or more of the following criteria:

  • Last modified date

  • Status, such as fixed (resolved) or open

  • Severity

  • Support cases

You can save searches that you perform frequently. You can also bookmark the URL for a search and email the URL for those search results.

Using the Cisco Bug Search Tool

For more information about how to use the Cisco Bug Search Tool, including how to set email alerts for bugs and to save bugs and searches, see Bug Search Tool Help & FAQ.

Before You Begin

You must have a Cisco.com account to log in and access the Cisco Bug Search Tool. If you do not have one, you can register for an account.

Procedure


Step 1

If you do not see this product listed, continue typing to narrow the search results.

  2. In the Releases field, enter the release for which you want to see bugs.

    The Cisco Bug Search Tool displays a preview of the results of your search below your search criteria.

Step 5

To see more content about a specific bug, you can do the following:

  • Mouse over a bug in the preview to display a pop-up with more information about that bug.

  • Click on the hyperlinked bug headline to open a page with the detailed bug information.

Step 6

To restrict the results of a search, choose from one or more of the following filters:

Filter

Description

Modified Date

A predefined date range, such as last week or last six months.

Status

A specific type of bug, such as open or fixed.

Severity

The bug severity level as defined by Cisco. For definitions of the bug severity levels, see Bug Search Tool Help & FAQ .

Rating

The rating assigned to the bug by users of the Cisco Bug Search Tool .

Support Cases

Whether a support case has been opened or not.

Your search results update when you choose a filter.
