[c-nsp] SNMP support for "ethernet-echo"(CFM LB) IP SLA failures counter

[Martin T]

Hi,

I have a Cisco ASR920(asr920-universalk9_npe.03.16.02a.S.155-3.S2a-ext.bin)
router with "ethernet-echo"(CFM LB) IP SLA configuration. Output of
"sh ip sla statistics" can be seen below:

asr920#sh ip sla statistics
IPSLAs Latest Operation Statistics

IPSLA operation id: 1
Type of operation: ethernet-echo
        Latest RTT: 3 milliseconds
Latest operation start time: 08:29:04 UTC Mon Mar 7 2016
Latest operation return code: OK
RTT Values:
        Number Of RTT: 1                RTT Min/Avg/Max: 3/3/3 milliseconds
Number of successes: 2061
Number of failures: 9
Operation time to live: Forever


asr920#


As seen above, there has been 9 failures. However, if I snmpwalk the
.1.3.6.1.4.1.9.9.42 subtree, then number of failures is not returned
by SNMP agent. Is there a similar OID to rttMonStatsCollectTimeouts
for "ethernet-echo" IP SLA?


thanks,
Martin
