I need to enable fips remotely on a Cisco Nexus 9K

 I need to enable fips remotely the solution is to follow the below steps: Enable fips N9K N9k-Switch# conf t N9k-Switch(config)# no feature ssh N9k-Switch(config)# no ssh key rsa N9k-Switch(config)# ssh key rsa 2048 N9k-Switch(config)# feature ssh New SSH Key has a bitcount of 2048: N9k-Switch(config)# show ssh key (check RSA keys) N9k-Switch(config)# fips mode enable (this required reload the switch) The issue is that I need to do this remotely thru ssh and ssh will disconnect, I was thinking of a tcl script, but not too familiar with tcl scripting. Is there a tcl or eem script that would work for this? Thank you, Dave

  - One other option could be , if the remote site can offer terminal services , it to access the console of the nexus through a terminal server equipment ,

 here is an EEM script you can run manually from the exec prompt (event manager run SSH_FIPS_ENABLE): event manager applet SSH_FIPS_ENABLE event none action 1.0 cli command "enable" action 2.0 cli command "configure terminal" action 3.0 cli command "no feature ssh" action 4.0 cli command "no ssh key rsa" action 5.0 cli command "ssh key rsa 2048" action 6.0 cli command "feature ssh" action 7.0 cli command "show ssh key" action 8.0 wait 5 action 9.0 cli command "fips mode enable" action 10.0 cli command "end" action 11.0 cli command "write memory"
