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.

You can specify different ACLs while configuring the SNMP community name,
SNMP group name, and SNMP user name.
As SNMP community name is a feature of SNMPv1 and SNMPv2c, the specified
ACLs in the command that configures SNMP community names (the snmp-agent
community command) take effect in the network management systems that
adopt SNMPv1 or SNMPv2c.
Similarly, as SNMP group name and SNMP username name are a feature of
SNMPv2c and the higher SNMP versions, the specified ACLs in the commands that
configure SNMP group names and SNMP user names take effect in the network
management systems that adopt SNMPv2c or higher SNMP versions. If you specify
