Step
10. (Optional.) Map an
SNMP community to
an SNMP context.
11. (Optional.) Configure
the maximum SNMP
packet size (in bytes)
that the SNMP agent
can handle.
12. Specify the UDP port
for receiving SNMP
packets.

Configuring SNMPv3 basic parameters

SNMPv3 users are managed in groups. All SNMPv3 users in a group share the same security model, but
can use different authentication and privacy key settings. To implement a security model for a user and
avoid SNMP communication failures, make sure the security model configuration for the group and the
security key settings for the user are compliant with
Table 7 Basic security setting requirements for different security models
