I've been trying to configure a NAM on one of our core switches and have come across an interesting issue. I was unable to add the NAM as a destination for any type of SPAN source.....I would put in the line for it:
"monitor session 1 destination analysis-module 6 data-port 1"
And it would look like it took it fine (no errors) but it wasn't in a 'show run'. I tried everything I could and as a last resort I deleted from the NAM what looked to be a "stale" SPAN session but it was actually one of the other 2 SPAN sessions we have running. The problem now is that I can't get that session back into the switch. Every time I run anything related to 'monitor session' I get the following error:
Core-6509-1(config)#monitor session 2 source interface Gi2/3
% Another session paramters or permit-list is being configured.
%Please wait for other configuration to complete.
I have verified that I am the only one logged into the switch and I have rebooted the NAM twice to make sure it wasn't holding onto anything. We have redundant core switches but I'm reluctant reboot this switch if there is another way to fix this. Thanks!
