CISCO TECHNICAL SUPPORT DOCUMENTATION
Interactive Configuration and Troubleshooting Voice Documents

The Technical Support Web team continuously creates new configuration examples and tech notes that address real-world scenarios. In April, the team published a new set of voice configuration resources on the Web that covers an end-to-end configuration and troubleshooting scenario. This series of interactive documents uses a typical head office and branch office to demonstrate common voice network configurations.

Together, these documents include:

  • End-to-end configuration of a typical voice network


  • Quick and easy navigation to the right device configuration


  • Visual depiction of the interdependencies of parameters across products


  • Numerous screenshots to describe step-by-step configurations


  • Interactive network diagram for selecting devices and features to configure

In the document below, you can view a network diagram and click the device and feature you are interested in:

New Reader Tip - UPDATE:
Using Command Aliases as Shortcuts

Note: All tips published in the Cisco Technical Services Newsletter are reviewed by Cisco technical support engineers. However, the Cisco Technical Services Newsletter and Cisco cannot guarantee the accuracy or completeness of these tips.

When troubleshooting performance problems on our campus backbone, we often need quick access to CPU and traffic stats; the commands can be lengthy, hard to remember (especially at 3:00 a.m.), and easily open to typos.

We use a lot of command aliases to provide quick shortcuts for complex commands. Here are a few examples from our core routers (Cat6513/Sup720/12.2(18)SXF5):

  • To check ARP traffic when we suspect an ARP storm, "alias exec arpstats show mls cef adjacency entry" lets us just type "arpstats 14" to see the ARP packet counts. (Note: The "arpstats" alias will need an entry number as an argument. In this example, "14" was used.)


  • To see the top CPU processes, "alias exec proc show processes cpu sorted | exclude 0.00%  0.00%  0.00%" lets us type "proc" to see a sorted list with all the minor ones excluded.

To find the interfaces handling the most traffic, a collection of aliases gives us quick access to the "collect top" commands:

  • "alias exec top collect top counters interface"
  • "alias exec top2 collect top counters interface layer-2"
  • "alias exec top3 collect top counters interface layer-3"
  • "alias exec topa collect top counters interface all"
  • "alias exec shotop show top counters interface report"
  • "alias exec notop clear top counters interface report"

And, of course, to see all of the aliases that we've defined, we do this: "alias exec alias show alias"

I'm sure you can think of other useful aliases to simplify and speed up your troubleshooting.

-Kurt Hillig, University of Michigan, Ann Arbor, Michigan, USA

Editor's Note: The "collect top counters interface" command does require an argument when used. Also, the CLI help still works just as well as it does for any use of the IOS CLI. So, typing "top ?" gives you a list of the valid arguments and also expands the alias for you.

If your Tip is selected for publication, you will receive a complimentary Cisco polo t-shirt from the Cisco Technical Services Newsletter staff.
