Tool Descriptions

In order to submit ideas for new tools or suggestions to enhance these tools, send us feedback as described in Submit Comments and Questions.

System Diagnostics

Supported platforms: ASA, IOS, IOS-XE, IOS-XR

This tool utilizes Cisco TAC knowledge in order to analyze a Cisco supported device and detect known problems such as system problems, configuration mistakes, and best practice violations.

Note: This analysis requires the output of the show tech-support command and is sent to Cisco in order to be processed. IOS-XR analysis will vary in the use of "show" commands.

Firewall Top Talkers

Supported platforms: ASA

This tool helps determine which connections that pass traffic through an ASA might have the highest bit rate during a certain period of time.

The tool compares two separate outputs of show conn or show conn all, taken a few seconds apart. It calculates the difference in the “bytes” value in order to see how much traffic each connection passed during the time between the first and second outputs. It also identifies new connections (those found in the second output but not the first).

The tool then displays a list of the connections of interest, sorted by amount of traffic. You can export the results in JSON or CSV format.

Traceback Analyzer

Supported platforms: ASA

This tool attempts to match the root cause of a crash to a known bug if the ASA has experienced a system traceback. If a match is found, the ASA version or versions in which the bug is fixed are provided.

Note: This analysis requires the output of the show crashinfo command and is sent to Cisco to be processed. All ASA software versions are supported.

Packet Tracer

Supported platforms: ASA

This tool allows administrators to send simulated packets through the ASA as a test. If the packet is dropped, the ASA configuration portion or feature that could have contributed to the packet drop is identified.

Note: ASA version 7.2 (the first version to include the command) and later are supported.

Unused Policy Detector

Supported platforms: ASA

This tool looks for unused configuration policies such as unused access-lists, object-groups, and objects. Some of these could also indicate misconfigurations. This tool collects the output of the commands show run and show access-list | excl ^ |elem. The output is uploaded to Cisco for analysis. Full tool functionality is available in ASA releases 9.x and above.

BGP Top Talkers

Supported platforms: IOS-XR

This tool helps determine which Border Gateway Protocol peers have the highest rates of messages sent or received during a certain period of time.

L2VPN Top Talkers

Supported platforms: IOS-XR

This tool helps determine which Layer 2 VPN point-to-point circuits and Bridge-Domains have the highest packet rates during a certain period of time.

LPTS Top Talkers

Supported platforms: IOS-XR

This tool helps determine the types of traffic that are handed off from hardware to software processing and their rates. Local Packet Transport Services (LPTS) is the router feature that decides which traffic (such as Telnet, SSH, and SNMP) must be handed off, and limits rates in order not to overload the software.

(A demonstration video of the new IOS-XR tools is available.)

IP Route Analysis

Supported platforms: IOS, IOS-XE, NX-OS

This tool provides four different reports based on the analysis of IPv4 or IPv6 routes. (The NX-OS platform supports only IPv4 routes.)

  • Route instability: checks for routing changes within a 60 second interval
  • Route summary with next hop
  • Routing table subnet prefix distribution
  • Summary of administrative distances for all protocols

Note: If the routing table has 100,000 routes or more, this tool will not work.

IOS and IOS-XE IP Multicast Analysis

Supported platforms: IOS, IOS-XE

This tool provides an analysis of the global IPv4 multicast traffic that is flowing through the device, as well as control plane traffic.

Crashinfo Analyzer

Supported platforms: IOS, IOS-XE

This tool analyzes a crashinfo file that you upload and compares the file's contents with known issues in order to determine the cause of the system reset.

Zone Based Firewall Visualizer

Supported platforms: IOS, IOS-XE

This tool creates a diagram that illustrates the complex and nested zone based firewall policies on the router.

L2VPN Service Check

Supported platforms: IOS-XR

This tool allows you to select an L2VPN Bridge-Domain or Xconnect. The tool then runs several "show" commands in order to determine the status of the L2VPN service.

Configuration Difference

Supported platforms: ASA, IOS, IOS-XR

This tool compares the startup configuration and running configuration of the device and color-codes them to highlight differences. It also allows you to download each configuration as a text file.

Packet Capture

Supported platforms: ASA, IOS, IOS-XE, NX-OS

This tool helps you set up and perform a packet capture and analyze the results. You can specify the kind of packets to capture based on the device platform, decode captured packets in the terminal, and view traffic analytics.

Case Create

Supported platforms: ASA, IOS, IOS-XE, IOS-XR

This tool automates the collection of support case data for supported platforms. For devices on other platforms (FX-OS, NX-OS, UCS), standard case creation is available.

TAC Data Collection

Supported platforms: ASA, IOS, IOS-XE, IOS-XR, NX-OS, UCS, AireOS (on Wireless LAN Controller)

This tool automates the collection of diagnostic data needed to resolve support cases. A TAC engineer provides a TaskID code to you. When you enter the TaskID into the TAC Data Collection tool, the CLI Analyzer automatically performs the diagnostic commands and uploads the output to the support case.

(A demonstration video of this tool is available.)

Show Run Diagnostics

Supported platforms: AireOS (on Wireless LAN Controller)

Show Tech Diagnostics

Supported platforms: AireOS (on Wireless LAN Controller)

NX-OS Health Diagnostics

Supported platforms: NX-OS

This tool detects and reports known issues such as system problems, configuration mistakes, and best practice violations, based on Cisco TAC knowledge.

NX-OS Upgrade Helper

Supported platforms: NX-OS

This tool provides supported upgrade paths for NX-OS 7K platforms.
