Nokia routers are based on SNMPv3. To use the routers with SNMPv1 and/or SNMPv2c, SNMP community strings must be configured. Three pre-defined access methods are available when SNMPv1 or SNMPv2c access is required. Each access method (r, rw, or rwa) is associated with an SNMPv3 access group that determines the access privileges and the scope of managed objects available. The community command is used to associate a community string with a specific access method and the required SNMP version (SNMPv1 or SNMPv2c). The access methods are:
Read-Only
Grants read only access to the entire management structure with the exception of the security area.
Read-Write
Grants read and write access to the entire management structure with the exception of the security area.
Read-Write-All
Grants read and write access to the entire management structure, including security.
If the predefined access groups do not meet your access requirements, then additional access groups and views can be configured. The usm-community command is used to associate an access group with an SNMPv1 or SNMPv2c community string. Nokia does not recommend associating a usm-community with an SNMP access group that is configured with the li (lawful intercept) context.
SNMP trap destinations are configured in the config>log>snmp-trap-group context.
