Searching for Bugs Using the Bug ID
To search for known ATM switch router software bugs using a know bug ID perform the following steps
using the Bug Toolkit search tool:
Step 1 In the data entry field enter the bug ID (for example, CSCds28912) and click the Search button.
Step 2 The entire window will be replaced with a “Bug Details” window with the search results.
If you chose you can save the bug details by clicking the Save Bug button at the bottom of the window.
This allows you to either:
• Save the bug details to a bug group that you create for reference later.
• Save your search criteria by providing a name allowing you to reference it later.
• Have e-mail updates to the bug mailed to you by entering your e-mail address.
Searching for Bugs Using the Software and Hardware Product Name
To search for known ATM switch router software bugs using the product name perform the following
steps using the Bug Toolkit search tool:
Step 1 In the data entry field enter the product name (for example, Catalyst 8540 MSR) to find it in the
scrollable list and click the Next button.
Step 2 Select the product name from the list that appears and click the Next button
Step 3 From the list of product names that appear in the list, select the one you want to search for bugs and click
the Next button.
Step 4 The original search window is replaced by a new window that allows you to limit search results using
one or more of these options:
1. Select version to search. Either a major revision or a specific revision from the drop-down menus.
2. Enter keywords to search bug title and description in the data entry field.
3. Set Advanced Options
Step 5 When you have selected all the needed search limiting fields, and click the Next button.
The entire window will be replaced with a “Bug Search Results” table with a list of bugs containing your
search criteria. Look at the Bug reports listed in the “Bug ID & Title” column. An existing bug entry that
describes the problem you are having may have been fixed in a more recent version of the IOS software.
Look in the “Fixed-in Version” column for a later version of the IOS software. All you might have to do
to solve your problem is upgrade your software.
If a software upgrade is not listed as a way to solve your problem, double-click on the Bug ID and read
the DDT details; a workaround might be listed there.
