Controlling Network Management Users by Source IP Addresses

You can manage a S4200G 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.
Defining an ACL
Applying the ACL to control users accessing the switch through SNMP
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 is achieved by
applying basic ACLs, which are numbered from 2000 to 2999.
