I need to wait until data is received but netopeer2-cli is showing processing timed out error.I also tried by increasing the timeout value by user-rpc –rpc-timeout 10 command, still getting the same error. can you please help us on the same?

[michalvasko]

Try to increase netppeer2-server timeout by running it with -t 10, for example.

[sowmi18]

Thanks!! It works Another doubt is there

user-rpc –rpc-timeout 10

ERROR type: application tag: operation-failed severity: error message: Callback event "rpc" with ID 1 processing timed out.

user-rpc –rpc-timeout 10

cli_send_recv: Timeout for receiving a reply expired.

What is the difference between these two errors?

[michalvasko]

The former means that the server timeout for a specific sysrepo RPC callback elapsed and so it sent this error to the client. The latter means that the client timeout for receiving a rpc-reply from the server elapsed.

[sowmi18]

Thanks for your quick response!!

[sowmi18]

What is the default timeout value for a rpc? I set the timeout to 5 secs, but i got this error Callback event "rpc" with ID 1 processing timed out before 5 secs.

[michalvasko]

You have not specified which timeout you mean but the default server timeout for sysrepo RPC callback is here and the client rpc-reply timeout is here.

[sowmi18]

Got the reason.Thanks @michalvasko
