LMS 4.2 communication protocol

[ChannaBasava Kalapurmath]

Hi All,

We are using the below functionality in the LMS 4.2

- Fault Monitoring (DFM)

- Performance Management (HUM)

- Inventory Collection and Configuration collections (RME)

On device side configuration currently we have configured the RO and RW strings (SNMPv2c). we need to remove the RW  string configuration from the device.   Is above functionality can work on RO string alone ??

I gone through below link where it says RW is not required for above functions apart from Common services. need to know the role of RW string in the common services.

Common services is the main administrative module of LMS and all the credentials are stored in CS which are than distributed to other modules like HUM, RME etc.

Under RME various individual features like Configuration management, Software Image Management (SWIM), NetConfig etc depends on SNMP RW strings, however not very much and a failure can easily be found if due to removal of RW strings.

Still we recommend to have RW strings unless there is a strict security policy surrounding RW strings.

Other than being the centralized credential repository Common Service has an internal connection to CiscoView and Device Centre which may also need RW strings often.

You can plan to remove it once and see the aftereffects and plan accordingly.

-Thanks
