Establishing a NETCONF session

After a NETCONF session is established, the device automatically sends its capabilities to the client. You must send the capabilities of the client to the device before you can perform any other NETCONF operations.

You can use the aaa session-limit command to set the maximum number of NETCONF sessions that the device can support. If the upper limit is reached, new NETCONF users cannot access the device. For information about this command, see Security Configuration Guide.

Before performing a NETCONF operation, make sure no other users are configuring or managing the device. If multiple users simultaneously configure or manage the device, the result might be different from what you expect.
