Generating an SSH Server Key
The Avaya Multiservice switch currently supports RSA and DSA key types.
You can specify the key length of 768, 1024, or 2048 bytes. A key of length
1024 bytes provides more robust security and is the default key type. The
key pair is saved to the local server.
* Important: If SSH is enabled and you regenerate the SSH
server key, you must disable and then reenable
SSH for the change to take effect. For information
on how to disable and reenable SSH, see “
Enabling
SSH on a TCP Port .”
