no data collected in NAM reported

Hi does anyone have any idea why host reports in NAM traffic Analyzer would be failing to collect data.

The data source is NDE.

Data for this host and NDE is being collected because it appears under 'monitoring' in the NAM traffic Analyzer


Re: no data collected in NAM reported

On which port is the NAM spanned to the switch? What I am getting at is make sure that the SPAN configuration is correctly configured. If the SPAN is configured incorreclty then the NAM will not work and the output will show 0 packets captured.

Re: no data collected in NAM reported

This scenario may or may not apply to you...we moved our NAMs to a 6509 running CatOS to new a new 6509 running 12.2(18) IOS and I was told to upgrade the code to 3.4(1a) and I didn't see any packets captured either. Come to find out that the mini-RMON is turned off by default on this versio of NAM code. It took me a couple days to find out that I needed to go into Setup, switch parms, then enable mini-RMON. Hope this helps.

Re: no data collected in NAM reported

Have you enabled nde export on the CatOS? This can be disabled whenever you removed a destination.

Also, make sure you have vlans selected to include in the export. Doing a show mls nde will tell you if packets have been exported, to rule out any configuration issues

You'll need to type: mls nde enable
