Manipulating IOS from Linux: Keeping Cisco Switches Consistent

By Kim Oldfield.

Published by The Open Source Developers' Conference Papers

In the course of my job looking after Cisco switches and routers I have written several tools which I now use daily. These tools are available under the GPL at http://oldfield.wattle.id.au/programs/cisco/
These tools are:
acllint: checks ACLs for redundant lines;
grepacl: show the ACL lines which will match given source and or destination IP addresses and/or ports;
iosrun.py: login to an IOS (or CatOS) device and run user specified commands, can also be used as a python module for more complex interaction;
ioslogin: wrapper around iosrun.py to login and give a command prompt.

This paper will demonstrate basic use of each of these tools, and talk about some of programs written which make use of iosrun.py.
