It seems that Write Command on Nexus Switchs is not available anymore, can you confirm ?
Is there a way to reactivate it or is there an another short command to save the running configuration on Nexus Switchs ?
Hi Jonathan, yes wr mem has been deprecated for the Nexus.
You could use the alias command to achieve something similar though
switch(config)# cli alias name wrmem copy running-configuration startup-configuration
Not the same but close
Cisco has finally delivered on their promise to remove the "write" command.
Cisco will not entertain any PER to put the "write" command back in for Nexus.
