15.4(3)M0.3

Description (partial)

Symptom:
Inconsistent GDOI Rekey SA behaviour can be observed after switching from the ISM Crypto Module to 
the OnBoard one. More precisely, in the case where the ISM Crypto Module is active all works fine, however once the
device switches to the OnBoard Crypto Module, there is a functional impact as TEK rekey material cannot be processed and installed anymore (all GDOI Rekey SA Connection IDs show value 0).

Conditions:
ISR G2 
IOS 15.4(3)M
GDOI/GETVPN
ISM and/or OnBoard based crypto accelerator
