Can´t get Apps-Data on NAM2


I have a cat6513 with NAM2. On Switch run´s native IOS version 12.1(13)E4 and on the NAM ist the Version 3.1.1a installed. And now my problem, i have established a span-session over the GUI. If I look after 1 hour in the MONITOR-TAB, there are no App´s Data available. The GUI print´s, that I establish a SPAN-Session.

Mini-Rmon is on every Interface enabled.

thanks for help

Re: Can´t get Apps-Data on NAM2


If your NAM cannot do data capture using its

web interface, you may need to run this command

on the NAM to clean up the RMON table:

config clear

Did you span the ports to the NAM or any VLAn

spanned to the NAM ?

Please have a look at the following link:

--) Check for the part

" Why am I having problems capturing packets, even

after I configured the capture settings in the

Capture Settings dialog box and clicked Start?"

Also here is how to configure the NAM and how to use the NAM web interface:

--> If it still doesn't work, then you may want

to try the following:

Try to configure a manual SPAN from the command

line of the switch " This is to see if that works fine."

Look into the following link on how to configure

it manually on the CLI of your Catalyst:

After i cleared the config and established a new span-session, the nam get´s app´s data.

You have to turn on the collections first under Setup->Monitor for your span source, other wise you'll not see any data under Monitor screens.
