IPFIX is not supported on SPBM NNI interfaces. The reason for the message is that an invalid LPID (logical port id) was being provided because the PIM port (i.e. the Port Interface Module) was outside of the expected range, namely outside 0 – 127. Subsequently, as the LPID of 3076 or 2908 is out of range, the LPID is also not associated with a slot either. This configuration of IPFIX on ISIS enabled ports is not yet supported.
Workaround: Disable IPFIX on the SPBM NNI interfaces.
