Bugs for Cisco IOS Release 15.6(1)S

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.
