Hi,
My question is that if I am using an SNMP read-write community string on the device, would Prime LMS still require
the logging credentials of the device via ie) telnet/ssh ?
The reason how I undertand this as long as the SNMP manager (Prime LMS) and the agent (end device) have the same read-write community,
couldn't the Prime LMS just write to the device without the standard logging credentials ? or is the logging credential of the device is a must for it
to push configuration to the device ?
Pls advise.
Many thanks.
Cheers,

Even though the SNMP communication is there between device and LMS, it is not possible to configure any device using SNMP, except for the RW variable and OIDs, which are limited in their scope.
It is not possible to configure, but to copy configuration to or from device using SNMP. See the following document to check further:
http://www.cisco.com/en/US/tech/tk648/tk362/technologies_configuration_example09186a0080094aa6.shtml
Many people use this manual process to copy configuration from device using SNMP, edit it and copy back to device to make configuration changes, but ideally no NMS server does it and LMS is no exception.
It uses transport Layer protocols like telnet/ssh to communicate with device like a normal user to configure commands, which in this case is done by Netconfig job.

Hi sanjay,
Yes ciscoworks needs Telnet/SSH crendentials for config archive job. Though SNMP RW creds are an option to connect to device to archive configuration from device, but this will not be able to get vlan.dat, as that is not supported via snmp and your archvie will always be partially collected.
Apart from configuration archive there is no need for ciscoworks to have the telnet/ssh creds. Following is the guide which has the list of all the applications and the device credentials required for proper functioning of the applications :

Hi Vinod,
Thank you for the response.
If I just want to push configuration to the device ie) creating a vlan on a switch via the snmp read-write string, does the telnet/ssh credential is still needed in this instance ? If looks like yes based on the table on the URL you sent me but I am trying to understand why this is needed if there is already a link between the manager and agent via the SNMP read-write community string.
Many thanks.
