[j-nsp] SCB-E

[david.roy at orange.com]

Hi,

Same results on my side... 

Just a precision to be sure that there is no mis-understanding : it's not triggered by SCB-E, it is a software issue... But currently we only have this release to play with SCB-E :-) 



Regards

Given that there is only one public JUNOS release which supports SCB-E, there aren't many options: 11.4R1 - and that one has unusable SNMP due to new PFE statistics request delays introduced (feature, not bug of
course!):

foo at lab-MX960> show snmp mib walk ifHCOutOctets | count    
Count: 413 lines

$ time snmpbulkwalk -v2c -c removed x.x.x.x ifHCInOctets > /dev/null
Timeout: No Response from x.x.x.x

real    0m26.380s
user    0m1.647s
sys     0m0.133s

PR/731833 - fix supposed to come in 11.4R3 slated for May.

So as far as things stand, SCB-E not deployable before mid 2012 earliest if (and that's a big "if" when looking at 10.4 experience) 11.4R3 is going to be usable.

Ah, and 11.4R1 floods your log with messages like:

mcsn[91713]: %DAEMON-6: krt_decode_nexthop: Try freeing: nh-handle: 0x0
nh-index: 1049083 fwdtype: 3

No idea wether that's service affecting - we haven't observed any impact due to that yet.

Best regards,
Daniel
