Configuring the NMS

The Switch 5500 supports 3Com’s network management products. SNMPv3 adopts username and password authentication. When you use 3Com’s network management products, you need to set usernames and choose the security level. For each security level, you need to set authorization mode, authorization password, privacy mode, privacy password, and so on. In addition, you need to set timeout time and maximum retry times.

You can query and configure an Ethernet switch through the NMS.

Precautions Authentication-related configuration on an NMS must be consistent with that on the devices for the NMS to manage the devices successfully.
