z
Applying the ACL to control users accessing the switch through SNMP
To control whether an NMS can manage the switch, you can use this function.
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
Controlling network management users by source IP addresses is achieved by applying basic ACLs,
which are numbered from 2000 to 2999.
Follow these steps to control network management users by source IP addresses:
