Hi,

I am only add all devices via IPM > Collector Management > Add Devices. I did turn off auto-sync, it remain the same, the source is only 2 device shown.

The router that appear in list was CISCO3825 and I had 4 unit of it same IOS, but only one appear.

How to check the router support CISCO-RTTMON-MIB ?

Please post the output of an snmpwalk of 1.3.6.1.4.1.9.9.42 for routers missing from the source list. Note: these days you need a feature set higher than IP BASE to get IP SLA support.

I did on all the routers, 7206/3825 router have no problem.

The following is a SNMP walk of device 122.255.97.7 starting from .1.3.6.1.4.1.9.9.42

2 device appear on source , 1 unit is 3825 router , another unit is cat3560 switch.

This switch I did snmpwalk, no RTT MIB, but it do appear.

It is a way to reset the IPM db or configuration. SO can start from ground zero.

I did reset db on CM/DFM , it help on this kind devices inconsistent problem.

Failed to snmpwalk the device. Please check your community string and starting OID, and try again.

Did you find an answer for this ?

I kind of have the same issue.

One of four identical routers shows as valid source, all show ok as destinations.

This router was not being added at first (auto) because it showed as already in ipm !!???

After an ipm delete, it was added an it's the

only one working.

More info: IPM is running in a slave DCR, at first the synch was not ok, so I broke it (standalone) and made it again.

Found another thread with the "answer".

Somehow DCR had bad credentials for some of the devices, SNMP WR is the one that matters for

collection sources.

I say "somehow" because all routers have same

credentials, and the same default credentials

were used at discovery for all...
