[c-nsp] Finding source of ISIS authentication failure

[Thomas Sillaber]

Hi,

have you tried "debug isis update-packets"? Works on SRC2:

000484: Jul  1 19:27:57.428: ISIS-Upd (<proc>): Rec L2 LSP <ID>, seq 1D, ht
65171,
000485: Jul  1 19:27:57.428: ISIS-Upd (<proc>): from SNPA <ID>
(GigabitEthernet2/0/0)
000486: Jul  1 19:27:57.428: %CLNS-4-AUTH_FAIL: ISIS: LSP authentication
failed
000487: Jul  1 19:27:57.428: ISIS-Upd (<proc>): LSP authentication failed

This box is running 12.2(33)SRC code. The TAC engineer and I haven't really
found a good way to find what we're looking for. I have found some debugs
that confirm that we're having an authentication problem but they also don't
show the source of the problem. Not even an interface.
