(The generated public key on the switch is always 896 bits.)
With a direct serial connection from a management station to the switch:
1. Use a terminal application such as HyperTerminal to display the switch's
public key with the show crypto host-public-key command (figure 6-5).
2. Bring up the SSH client's "known host" file in a text editor such as Notepad
as straight ASCII text, and copy the switch's public key into the file.
3. Ensure that there are no changes or breaks in the text string. (A public
key must be an unbroken ASCII string. Line breaks are not allowed
Changes in the line breaks will corrupt the Key.) For example, if you are
using Windows® Notepad, ensure that Word Wrap (in the Edit menu) is
disabled, and that the key text appears on a single line.
4. Add any data required by your SSH client application. For example Before
saving the key to an SSH client's "known hosts" file you may have to insert
the switch's IP address:
Exponent <e>

client application.
Displaying the Public Key. The switch provides three options for display-
ing its public key. This is helpful if you need to visually verify that the public
key the switch is using for authenticating itself to a client matches the copy
of this key in the client's "known hosts" file:
