am having problem in archiving config from switches in cisco works. am having problem in only 5 switches all others switch configurations archived when I try to do this I found following error.
TELNET: Failed to establish TELNET connection to 172.25.2.102 - Cause: Authentication failed on device 3 times. PRIMARY-RUNNING config Fetch Operation failed for TFTP. Failed to detect SSH version running on the device. Failed to fetch config using RCP.Connection refused: connect Verify RCP is enabled or not.
What protocol should work for these devices? That is, should telnet succeed? Should SSH? The error here first points to RME not being able to login to the device via telnet due to invalid credentials for the device in DCR. If telnet should succeed, confirm the credentials in DCR are correct. If they are, and the problem persists, start a sniffer trace filtering on tcp/23 traffic to the device, and perform another sync archive job. When it fails, the sniffer trace should reveal why.
If SSH should work, make sure you can SSH to the device from the RME server, and login using the credentials in DCR.
If SNMP/TFTP should work, make sure the SNMP read-write credential in DCR is correct for the failing devices. Also, make sure that udp/69 and all ephemeral UDP ports are open between the server and device. A sniffer will also work here. You can filter on all UDP traffic between the RME server and the device. When the job fails, the sniffer trace should show why.
Thanks for that apparently nearly 200 switches are working only 5 switches we have a problem. please see snmp config below. I have added RW recently it is not taking effect. please see screen shot of working one and not working
You need to go to Common Services > Device and Credentials > Device Management, click the Edit Credentials button, then fill in the missing credentials for those five devices. Then run a new Device Credential Verification job (not just the report, but schedule a new job to run).

I am going to design and build an LAN network under a tunnel underground with long distance between the switches.
I will have 2 Catalyst switches and 8 Industrial IE3000, and they will be connected with fiber.
