Version
Indicates the supported SNMP version. Possible versions include:
SNMP v1
: supports SNMP version 1.

Read Community
Indicates the read community string for permitting access to SNMP agent. The
allowed string length is 0 to 255, and only ASCII characters from 33 to 126 are
allowed.
The field is applicable only when SNMP version is SNMPv1 or SNMPv2c.
SNMPv3 uses User-based Security Model (USM) for authentication and
privacy, and the community string will be associated with SNMPv3 communities
table. It provides more flexibility to configure security name than a SNMPv1 or
SNMPv2c community string. In addition to community string, a particular range
of source addresses can be used to restrict source subnet.
Write Community
Indicates the write community string to permit access to SNMP agent. The
allowed string length is 0 to 255, and only ASCII characters from 33 to 126 are
allowed.
The field only suits to SNMPv1 and SNMPv2c. SNMPv3 uses USM for
authentication and privacy and the community string will be associated with
SNMPv3 community table.
Engine ID
Indicates the SNMPv3 engine ID. The string must contain an even number
between 10 and 64 hexadecimal digits, but all-zeros and all-'F's are not
allowed. Change of the Engine ID will clear all original local users.
