Configuring Secure Shell (SSH)
General Operating Rules and Notes
General Operating Rules and Notes
Public keys generated on an SSH client must be exportable to the 
switch. The switch can only store ten keys client key pairs. 
The switch’s own public/private key pair and the (optional) client 
public key file are stored in the switch’s flash memory and are not 
affected by reboots or the 
erase startup-config command.
Once you generate a key pair on the switch you should avoid re-
generating the key pair without a compelling reason. Otherwise, you 
will have to re-introduce the switch’s public  key on all management 
stations (clients) you previously set up for SSH access to the switch. 
In some situations this can temporarily allow security breaches.
On ProCurve switches that support stacking, when stacking is 
enabled, SSH provides security only between an SSH client and the 
stack manager. Communications between the stack commander and 
stack members is not secure.
The switch does not support outbound SSH sessions. Thus, if you 
Telnet from an SSH-secure switch to another SSH-secure switch, the 
session is not secure
.
