Figure 164 A public key generated by the switch

NOTE: The generated public key on the switch is always 896 bits.

With a direct serial connection from a management station to the switch:

a. Use a terminal application such as HyperTerminal to display the switch public key with

the show crypto host public-key command, see Figure 163 (page 230).

b. Bring up the SSH client's "known host" file in a text editor such as Notepad as straight

ASCII text, and copy the switch public key into the file.

c. 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.

d. 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 IP address:
