NB3000-Line-Hd User Manual 4.2
SNMP Authentication
When running in SNMPv3, it is possible to configure the following authentication settings:
Parameter
SNMPv3 Authentication
Authentication
Defines the authentication (MD5 or SHA)
Encryption
Defines the privacy protocols to use (DES or AES)
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 define its communities and authoritive host which will be
granted administrative access.
Parameter
SNMPv1/v2c Authentication
Read community
Defines the community name for read access
Admin community
Defines the community name for admin access
Allowed host
Defines the host which is allowed for admin access
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 firewall.
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:
