Symptoms

When using an AES-GCM cipher on highly fragmented SSL records, platforms with Cavium Nitrox cards might report Bad records.

Impact

The BIG-IP system disconnects Client SSL connections prematurely. The SSL profile shows a number of Bad records.

Conditions

The negotiated cipher is one of the AES-GCM ciphers, and the MTU is such that the SSL records are highly fragmented.

Workaround

None.

Fix Information

The processing buffers reserve the proper number of subsequent parameters.
