Numerous network management tools use SNMP for requesting information from network devices. LANmonitor also uses SNMP to access the devices to display information about current connections, etc., or to execute actions such as disconnecting a connection. SNMP can be used to configure devices. For this reason TACACS+ requires authentication for SNMP access requests. Since LANmonitor regularly queries these values, a large number of unnecessary TACACS+ connections would be established. If authentication, authorization and accounting by TACACS+ are activated, then each request would initiate three sessions with the TACACS+ server.
This parameter allows the regulation of the behavior of devices with regard to SNMP access in order to reduce the number of TACACS+ sessions required for accounting. Authentication via the TACACS+ server remains necessary if authentication for TACACS+ is activated generally.
- SNMP ID:
- 2.54.12
- Console path:
- Setup > Tacacs+
- Possible values:
- only_for_SETUP_tree
- With this setting, accounting via TACACS+ server is only required for SNMP access via the setup branch of LCOS.
- all
- With this setting, accounting by TACACS+ server will be carried out for every SNMP access. In case of regular request for status information, for example, the load on the TACACS+ server will increase significantly.
- None
- With this setting, accounting by TACACS+ server will not be carried out for SNMP accesses.
- Default:
- only_for_SETUP_tree
