Controlling Network Management Users by Source IP Addresses
You can manage a H3C S5120-SI 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
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).
