Nblade.cifsNonAesNiBytesProc

Severity

ALERT

Description

This message occurs when a system with CPUs that do not support the AES-NI instruction set is performing SMB3 encryption or signing of a large amount of data. These cryptographic operations can degrade performance severely for both SMB and other system operations.

Corrective Action

Avoid encrypted or signed SMB3 traffic on systems that do not support the AES-NI instruction set.

Syslog Message

Excessive SMB3 cryptographic processing load (AES-NI instruction set is not supported).

Parameters

(None).
