crypto key pubkey-chain knownhosts
This command adds a public key of the specified SSH server to the known host database
on your switch. The SSH client on your switch uses this public key to verify the remote SSH
server.
The key is retrieved from the server. Before adding a key to this database, check that the
key sent to you is correct.
If the server’s key changes, or if your SSH client does not have the public key of the remote
SSH server, then your SSH client will inform you that the public key of the server is
unknown or altered.
The no variant of this command deletes the public key of the specified SSH server from
the known host database on your device.
Syntax crypto key pubkey-chain knownhosts [ip|ipv6] <hostname> [rsa|
