Issue:

I have configured IP SLA ICMP-Echo tests on a Cisco router. After modeling the Cisco router, when I try to discover the pre-configured ICMP-Echo tests, discovery failed, 0x456005c event, i.e. SPM Test Discovery Completion event, shows the following message:

   RTM_Test not populated for test ID xx. Reason: Test URL is invalid. 

Environment:  

All Spectrum versions.
Cisco router with 12.4.24(t) IOS version.

Cause: 

This issue is due to rttMonEchoAdminTargetAddress OID (1.3.6.1.4.1.9.9.42.1.2.2.1.2) has 0.0.0.0 value. The rttMonEchoAdminTargetAddress OID is described as the following:

rttMonEchoAdminTargetAddress OBJECT-TYPE
SYNTAX RttMonTargetAddress
ACCESS read-create
STATUS current
DESCRIPTION
"A string which specifies the address of the target."
::= { rttMonEchoAdminEntry 2 }
-- 1.3.6.1.4.1.9.9.42.1.2.2.1.2

Spectrum requires rttMonEchoAdminTargetAddress to have valid IP Address value to be able to discover and model the tests. This is Cisco device SNMP MIB data issue and not Spectrum's problem.

Resolution/Workaround: 

In one occasion upgrading the router's IOS version to 12.4.25(C) has resolved the problem. You should ask Cisco to address the SNMP MIB database issue.
