主要讨论的是如何在主干网上为SNMP提供安全性。通过比较SNMPv3内建的安全特性和SNMPv2配合IPSec这两种不同的实现方法,得出:在大型网络上,SNMPv2配合IPSec比SNMPv3在功能和性能上具有更多的优点。最后,提出将这两种实现方案配合使用的方法将更加适合大型主干网上对SNMP设备的管理。
The main discussion is how to provide SNMP security on the backbone. By comparing the built-in security features of SNMPv3 and the two different implementations of SNMPv2 and IPSec, it is concluded that SNMPv2 and IPSec have more advantages in functionality and performance than SNMPv3 on large networks. Finally, it is proposed that the combination of these two implementations will be more suitable for the management of SNMP devices on large backbone networks.
