BIGpipe parsing error:

 

012e0028:3: There is no valid configuration to save.i think error message from b save is not really useful. b load would give more useful infromation about what wrong is. for example, Business-VLAN was not found. so, you may have to create Business-VLAN vlan and try b load again to see if there is any other error. after fixing all error, b save should work.
