Prerequisites 
The controlling policy against network management users is determined, including the source IP 
addresses to be controlled and the controlling actions (permitting or denying). 
Controlling Network Management Users by Source IP Addresses 
This configuration needs to be implemented by basic ACLs; a basic ACL ranges from 2000 to 2999. For 
more information about ACLs, see ACL in the ACL and QoS Configuration Guide. 
Follow these steps to control network management users by source IP addresses:

Required 
According to the SNMP version 
and configuration customs of 
NMS users, you can reference 
an ACL when configuring 
community name, group name 
or username. For the detailed 
configuration, see SNMP in the 
Network Management and 
Monitoring Configuration Guide.
 
Configuration Example 
Network requirements 
Only SNMP users sourced from the IP addresses of 10.110.100.52 and 10.110.100.46 are permitted to 
access the AP .
