I had this error in the logs of some of my 3650 switches that was running Everest 16.6.4. I upgraded to 16.6.4a to remedy high cpu from SISF process while running DHCP snooping. The upgraded fixed the SISF process but the error remains in my logs. This is a single IDF switch on one of my campuses. Looking at the bug details it was discovered on 3850 switches running Polaris 16.6.1. It was also reported that it was random. This error is filling up my log buffer.
Anyone else experiencing this?
