7.3 Controlling Network Management Users by Source IP
Addresses
You can manage a H3C S7500E series Ethernet switch through network management
software. Network management users can access switches through SNMP.
You need to perform the following two operations to control network management users
by source IP addresses.
z Defining an ACL
z Applying the ACL to control users accessing the switch through SNMP
7.3.1 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).
