[j-nsp] Strange Log about GRE Keepalive

[Niall Donaghy]

Hi Alireza,

If you want to suppress this message from the on-box log files, you can do
something like this on MX - not sure about M320:

	set system syslog <file> <target> match "!(fpc.*pfe doesn't support
GRE Keepalives)"

To suppress the message from going to your syslog server, you can try this -
but I haven't tested this myself:

	set system syslog <host> <target> match "!(fpc.*pfe doesn't support
GRE Keepalives)"

Finally, this is not applicable in your case but might help someone
searching the archive in future.
If you have an MS-MIC card on MX-series, you can alter the syslog severity
in the syslog process on the MS-MIC itself. 
We needed this workaround to stop the eventd process hogging CPU due to
excessive error messages from the MS-MIC using Netflow v9 with mpls-ipv4
template; the errors are 'cosmetic' but nevertheless hogging the main RE
CPU, if generated.

	set chassis fpc 9 pic 0 adaptive-services service-package
extension-provider syslog daemon critical

HTH,
Niall
