47.5.4.3no ssh

Syntax:

no ssh key <rsa1rsadsa> no ssh known-hosts <host-ip>

no ssh known-hosts <host-ip> [1024ssh-rsassh-dsa] where

key <rsa1rsadsa>	=	Disables the secure shell server encryption key. Your
		Switch supports SSH versions 1 and 2 using RSA and
		DSA authentication.
known-hosts <host-ip>	=	Removes a specific remote host from the list of all
		known hosts.
known-hosts <host-ip>	=	Removes remote known hosts with a specified public
[1024ssh-rsassh-dsa]		key type (1024-bit RSA1, RSA or DSA).

An example is shown next.

•Disable the secure shell RSA1 encryption key.

•Remove the remote host with IP address 172.165.1.8 from the list of known hosts.

•Remove the remote host with IP address 172.165.1.9 and with an SSH-RSA encryption key from the list of known hosts.
