You can specify an ACL for the user and group, respectively, to filter illegitimate NMSs. Only the
NMSs permitted by the ACLs for both the user and group can access the SNMP agent. The following
rules apply to the ACLs for the user and group:
•
If you do not specify an ACL, the specified ACL does not exist, or the specified ACL does not
have any rules, all NMSs that use the username can access the SNMP agent.
•
If you have specified an ACL and the ACL has rules, only the NMSs permitted by the ACL can
access the agent.
For more information about ACL, see
ACL and QoS Configuration Guide
