Bugs for Cisco IOS Release 15.5(1)S

Open and Resolved Bugs

Bugs describe unexpected behavior in Cisco IOS software releases. Severity 1 bugs are the most serious bugs; severity 2 bugs are less serious. Severity 3 bugs are moderate bugs, and only select severity 3 bugs are included in this section.

In this section, the following information is provided for each bug:

Symptoms—A description of what is observed when the bug occurs.
Conditions—The conditions under which the bug has been known to occur.
Workaround—Solutions, if available, to counteract the bug.

Note If you have an account on Cisco.com, you can also use the Bug Toolkit to find select bugs of any severity. To reach the Bug Toolkit, log in to Cisco.com and go to http://www.cisco.com/cgi-bin/Support/Bugtool/launch_bugtool.pl. (If the defect that you have requested cannot be displayed, this may be due to one or more of the following reasons: the defect number does not exist, the defect does not have a customer-visible description yet, or the defect has been marked Cisco Confidential.)

This section consists of the following subsections:

Using the Bug Search Tool

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

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.

Note 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.

To use the Cisco Bug Search Tool:

1. In your browser, navigate to the Cisco Bug Search Tool.

2. If you are redirected to a Log In page, enter your registered Cisco.com username and password and then, click Log In.

3. To search for a specific bug, enter the bug ID in the Search For field and press Enter.

4. To search for bugs related to a specific software release, do the following:

a. In the Product field, choose Series/Model from the drop-down list and then enter the product name in the text field. If you begin to type the product name, the Cisco Bug Search Tool provides you with a drop-down list of the top ten matches. If you do not see this product listed, continue typing to narrow the search results.

b. 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. You can mouse over bugs to see more content about a specific bug.

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