I would like ask the comunity about error in radius log on ACS 4.2(0) buld 124 Patch 12:


[079] EAP Message valuse: Dest buf len 512 smaller then data len 759.


Is this critical error, which deeply broke an EAP coversation between authenticator and server?

Where could I trigger the buffer lenght?

Hi,

This is a cosmetic issue and should not cause any issues.

Looks like ACS is trying to put 759 bytes into a 512 payload.


EAP should handle fragmentation, ie packaging up large blobs of data into smaller RADIUS EAP-Message attributes.


So this in itself shouldnt be a problem.


Hard to say without any context.
