Differences between R77.30 to R80.10 ?

[binhminhitc]

Hi,

During my last upgrade from R77.30 to R80.10, I get a little issue with RPC ports.

My customer use a group called ALL_DCE_RPC, and Dynamic RPC port like tcp/49155 was allowed through this group on R77.30 version, but seems not in R80.10 take 103.

Solution was simple: add new service in the concerned rule.

However, for my personal information and next upgrade, I want to understand.

I have already double checked on release note and somes SK, but didn't find anything...

Someone have an explanation about this ?

Thanks in advance for your help.

Best regards,
