Sample configuration 

Solution
The default SNMP configuration for the DFE includes a single community name - "public" - which grants read-write access to the whole MIB tree for both SNMPv1 and SNMPv2c. 
See 5116, about configuring for SNMPv1 and traps. 
See 5086, about configuring for SNMPv3. 
See 5610, about configuring SNMP views. 
See 5232, for router MIB access. 

For SNMPv1, here is what is already in place:

set snmp community public
set snmp group groupRW user public security-model v1
set snmp access groupRW security-model v1 read All write All notify All
set snmp view viewname All subtree 1

Note: Any use of the parameter 'All' must be exactly as shown here (or, to be more precise, exactly as defined in the 'set snmp view' statement, determining which portion of the mib tree will be acccessible). Using any other variation (including, but not limited to, values such as 'all' or 'ALL') will generate no errors, but will not work! 

To add a new SNMPv1 community name with the same permissions, you would use the following command sequence. In this example, the new SNMPv1 community name is "newname":

set snmp community newname
set snmp group groupRW user newname security-model v1

To remove a community name , you would use the following command sequence. In this example, the SNMPv1 community name to be removed is "public":

clear snmp community public

The 'set snmp group groupRW user public security-model v1' statement may be left in place, in case it is desired to re-activate the "public" community name at some point; or it can be cleared as well. 

As another example, here is how you would add an SNMPv1 community name for read-only access using the already-defined 'All' view of the entire mib:

set snmp community Ronly
set snmp group groupRO user Ronly security-model v1
set snmp access groupRO security-model v1 read All
