check-sync is taking more than 15 minutes on a nexus device

[yli7]

  I have a customer who added a number of nexus devices into NSO. However, when he did check-sync on some devices, it would take more than 15 minutes to complete. He's not too happy about it. I know we recently improved IOS ned to optimize the check-sync performance. Does anyone know if the NEXUS NED is going to have a similar improvement?

thanks,

Hi,

Usually these optimisation are under ned-settings for the respective device/ned-type.

The default is to take a hash. Anything better is platform dependent.

For nexus, I see there is an option of "device-command" which allows the use of a custom command to ascertain changes to config:

admin@ncs(config-device-n7k1)# ned-settings cisco-nx-transaction trans-id-method

Possible completions:

  config-hash      Use a snapshot of the running config for calculation (default)

  device-command   Use a device-side command to get a value to use for trans-id

admin@ncs(config-device-n7k1)# ned-settings cisco-nx-transaction trans-id-method

Would this help?

  Thanks, Bilal. I will ask the customer to give it a try.
