Troubleshooting DVMRP DVMRP Troubleshooting
OmniSwitch Troubleshooting Guide September 2005 page 15-5
The third command turns on the debug level. The low is 0, which is no debugging at all, and the high is
110, which prints everything to the screen. There is so much going on in the switch and so much put to the
screen that an explanation of what level would bring what output. Instead we are recommending that a
setting of 95 is the most useful setting. If that setting does not yield the required information to derive the
problem the Customer Support will engage Engineering for more help.
Below is a recommended setting for use in conjunction with customer support. Keep in mind that more
testing may be needed, as this may not yield a reason for a failure. Follow the Customer Support Engi-
neers instructions. It is a good practice to disable DVMRP and then enable after the debug set-up is
accomplished. This is so you capture the entire communication between DVMRP routers.
