Cause:

These error messages are seen when an ae bundle interface is configured with storm control in EX4300 series switches. This is because of the periodic 1 sec polling of the storm control counters (pfe_bcm_scntl_periodic_read_1sec), wherein the ae IFD is passed to pfe_ifd_get_port_num() to retrieve port num, which is unexpected.

Solution:

This issue is fixed in Junos OS 13.2X51-D20 and Junos OS 15.1R1. Since these messages do not impact service, they can be safely ignored.
