archive config from exec mode not working on Nexus 9k?

Working on a 9300 right now and I wanted to know how this works
The docs say that after you configure the archive, besides the periodic saves you can commit the config voluntarly with *archive config *

http://marker.to/fhdp7U

for me this is working only of I enter in the archvie config mode
switch(config)# archive config
^ % Invalid command at '^' marker.

then this works
switch(config-archive)# archive config
switch(config-archive)#

here is my config

archive
path bootflash:
time-period 5
maximum 14
write-memory
