Cisco Bug Search

Bug Search Tool (BST), the online successor to Bug Toolkit, is designed to improve your effectiveness

in network risk management and device troubleshooting.

BST allows partners and customers to search for software bugs based on product, release, and keyword,

and aggregates key data such as bug details, product, and version. The service has provision to filter bugs

based on credentials to provide external and internal bug views for the search input.

Check out Bug Search Tools & Resources on Cisco.com. For more details on the tool overview and

functionalities, check out the help page, located at

Understanding Preventive Maintenance

The following actions will help you maintain your sensor:

• Back up a good configuration. If your current configuration becomes unusable, you can replace it

with the backup version.

• Save your backup configuration to a remote system.

• Always back up your configuration before you do a manual upgrade. If you have auto upgrades

configured, make sure you do periodic backups.

• Create a service account. A service account is needed for special debug situations directed by TAC.

Caution You should carefully consider whether you want to create a service account. The service account

provides shell access to the system, which makes the system vulnerable. Analyze your situation to decide

if you want a service account existing on the system.

Configuration File, page E-3.

• For the procedure for using a remote server to copy and restore the a configuration file, see Backing

Up and Restoring the Configuration File Using a Remote Server, page E-3.
