SNMP Authentication
When running in SNMPv3, it is possible to con gure the following authentication settings:
Parameter
Authentication
Encryption
In general, the admin user can read and write any values. Read access will be granted to any
other system users.
There is no authentication/encryption in SNMPv1/v2c and should not be used to set any
values. However, it is possible to de ne its communities and authoritive host which will be
granted administrative access.
Parameter
Read community
Admin community
Allowed host
Attention must be paid to the fact that SNMP passwords have to be more than 8 characters
long. Shorter passwords will be doubled for SNMP (e.g. admin01 becomes admin01admin01).
Please note that the SNMP daemon is also listening on WAN interfaces and it is therefore
suggested to restrict the access with the rewall.
Typical SNMP Commands
Setting MIB values and triggering extensions is generally limited to the SNMPv3 admin user.
It is possible to specify an administrative host for SNMP v1/2c.
The SNMP extensions can be read and triggered as follows:
