IPM 4.2 and SNMP trap.

Question

Hello at all.
We are using IPM 4.2 to configure SLA operations on 7201 with software 12.4(24)T4, downgraded from 15.0 because IPM cannot configure collectors.
When we receive a trap the tag is empty for all collectors.
Performing a SNMP Walk on rttMonCtrlAdminTag we can see the tag.
When we manually define a collector the originated trap has tag populated correctly.
In this last case we can use tag with more than 15 chars also.
Regards.
Andrea

As stated in the other IP SLA thread, you are seeing CSCte85239.  The bug was filed against 12.4(15)T, and wasn't fixed until 15.1(3)T.  However, as you found, the 15.0(1)M4 image was not affected by the bug as it must have been branched before the bug was introduced.
As a workaround, given that you have EEM 3.0 support in 12.4(24)T, you could create an applet that sends a customized trap with all of the necessary data.  See https://supportforums.cisco.com/docs/DOC-11745 for details on how to create customized traps using EEM.  Essentially, you will create an EEM applet (or Tcl) policy that intercepts the required IP SLA reaction condition, then runs the necessary show commands to extract the parameters you need to generate the trap you want.  This one policy could be defined outside of IPM, but it could be used for all collectors on the device.
