Generating the
Host Key Pair
Use the Security > SSH (Configure Host Key - Generate) page to generate a host
public/private key pair used to provide secure communications between an SSH
client and the switch. After generating this key pair, you must provide the host
public key to SSH clients and import the client’s public key to the switch as
described in the section “Importing User Public Keys” on page 275 .
Note: A host key pair must be configured on the switch before you can enable the
SSH server. See “Configuring the SSH Server” on page 272 .
