Troubleshooting Assistant Tool:
New ATM and Authentication Knowledgebases Use Step-by-step Analysis
to Quickly Resolve Networking Problems
The Cisco
TAC Troubleshooting Assistant tool ATM and Authentication knowledgebases
have been completely updated by Cisco TAC engineers to accurately
troubleshoot your most current networking problems. Both ATM and
Authentication knowledgebases offer all new troubleshooting content
in a step-by-step format. The Authentication knowledgebase also
offers advanced search formats that cover both local and server-based
authentication issues.
Because the
Troubleshooting Assistant simulates the actual process that a
TAC engineer uses when diagnosing a network problem, this tool
is especially effective when you are troubleshooting an unfamiliar
technology area. The Troubleshooting Assistant asks you questions
about your technical issue and leads you to a solution.
The Access
and LAN switching knowledgebases of the Troubleshooting Assistant
have also recently been completely rewritten to bring you up-to-date
troubleshooting information. Be on the lookout for new technology
areas coming out shortly!

Tool for IBM Technologies:
Cisco TAC Bitswapping Tool Performs Instantaneous Bit Swaps of
MAC Addresses
The TAC
Bitswapping Tool saves you valuable time when you need to convert
MAC addresses from Ethernet to Token Ring. This easy-to-use tool
performs instantaneous and automatic bit swapping of MAC addresses
from Ethernet (canonical format) to Token Ring (non-canonical
format). The tool also accepts a variety of address formats, so
you can use the format that is most convenient for you.

If the AS path
length is longer than 50 ASs, the router uses regular memory
allocation and returns the "#%BGP-3-INSUFCHUNKS Insufficient chunk
pools for aspath" error message every time it encounters this
situation. This Tech Tip explains how to avoid this situation.
