Re: ISIS Adj Change

Hello Paolo,

you have more then guest access on CCO you can use the error message decoder to find info about the messages

http://www.cisco.com/pcgi-bin/Support/Errordecoder/index.cgi

if you want to understand why an IS-IS adj is not stable you can use:

debug isis adj-packets

as a reference link you can use

http://www.cisco.com/en/US/docs/ios/iproute/configuration/guide/isinitcf.html#wp1054967

Hope to help

Re: ISIS Adj Change

Hello Paolo,

if you mean

%CLNS-3

the 3 here is the severity level of the event

with 3 more important then 4

Otherwise you should look at TAC case studies for example

best regards
