SNMP Access Control:
Simple Network Management Protocol—software on a PC within the LAN is required to
use this function.
SNMP V1 and V2:
Read Community – Specify a name to be identified as the Read Community, and an IP
address. This community string is checked against the string entered in the configuration
file. Once the string name is matched, you can obtain this IP address and are able to
view the data.
Write Community – Specify a name to be identified as the Write Community, and an IP
address. This community string is checked against the string entered in the configuration
file. Once a string name is matched, users from this IP address are able to view and
modify data.
Trap Community – Specify a name and an IP address. This community string is
checked against the string entered in the configuration file. Once a string name is
matched, users from this IP address are sent SNMP Traps.
SNMP V3:
Specify a name and password for authentication, and define access rights from the
identified IP address. Once authentication has succeeded, users from this IP address are
able to view and modify data.
SNMP Version: SNMPv2c and SNMPv3
SNMPv2c is the combination of the enhanced protocol features of SNMPv2 without the
SNMPv2 security. The "c" comes from the fact that SNMPv2c uses the SNMPv1
community string paradigm for "security" but is widely accepted as the SNMPv2
standard.
SNMPv3 is a strong authentication mechanism with fine granularity for remote
monitoring.
Traps supported: Cold Start, Authentication Failure.
