Configuring SSH key pairs

Perform this procedure to configure SSH key pairs for nodes and switches.

1. To configure an SSH key pair for a software-only node, run these commands:

   # below command will generate SSH Key pair in /tmp directory
   ssh-keygen -m PEM -b 2048 -t rsa -f /tmp/sshkey-key1 -q -N ""
    
   # To copy public key to software only node
   ssh-copy-id -i /tmp/sshkey-key1.pub root@100.68.105.233
    
   # Keys can be copied for both root and non-root users

2. To configure an SSH key pair for a Cisco Nexus switch, run these commands to add the public key:

   username pfxmsvc password <password> role priv-15
    
   username pfxmsvc sshkey ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDWxvVQ9PgfFI3NMsg3TsR9G89ykZ3UEyciz47hcXH/YXNakva5PV5l7ubHY4nUxKj3zpVHXg/Bq9zRK5lQFs4KGC5eaYB9nm2xEwhuhpvsCvROo8SzjjTNRcpok2EMD/3VhuZAWdaXITSukq2D1Ek5W7qeE0LiLSC+2s0u6iPTU5KHs3mrELbRlxpVxnHQtrgUZnsLvkxwzuEnBKWNIEZ06HoDLP1vBCaYJslE5iDseUCZstWvFbvkaeE4FOrqohllAhVGVH19B6Q38ijVjLAwjXX03a6IQqeWj+JkpHpB61vMsAqqje4pm9VFzAY2NAcvoBo7Oab+52qA1vJTCbG7
