net-snmp是否支持AES-192和AES-256加密？ [英] Does net-snmp support AES-192 and AES-256 encryption?

问题描述

网络设备已配置有使用AES192作为隐私协议的snmpv3用户。

The network device has been configured with snmpv3 users which uses AES192 as the privacy protocol.But when the following command is executed

snmpwalk -v3 -l authPriv -u user -a SHA -A authpass -x AES256 -X privpass device_ip:161 oid

它引发以下错误

Invalid privacy protocol specified after -x flag: AES256

但是当我尝试使用AES128加密时，snmpwalk运行得很好，这让我想如果不支持AES192& 256功能，为什么？

but when i tried using AES128 encryption the snmpwalk worked perfectly fine,which made me think if AES192&256 features are supported if not why was it not included.

推荐答案

原始SNMP RFC文档不需要这些文件。

The original SNMP RFC documents do not require those.

因此，以及Net-SNMP永远不支持它们的其他原因，

Thus, along with other reasons Net-SNMP never supports them,
