quoted with single quotes ('keystring'). The following restrictions for a

keystring apply.

• A keystring cannot contain both single and double quotes.

• A keystring cannot have extra characters, such as a blank space or a new

line. However, to improve readability, you can add a backlash at the end

of each line.

NOTE: The ip ssh public-key command allows you to configure only one

SSH client public key at a time. The ip ssh public-key command behavior

includes an implicit append that never overwrites existing public-key configurations

on a running switch.

If you download a software configuration file that contains SSH client publickey

configurations, the downloaded public keys overwrite any existing keys, as happens

with any other configured values.

To display the SSH public-key configurations (72 characters per line) stored in a configuration file,

enter the show config or show running-config command. The following example shows

the SSH public keys configured for manager access, along with the hashed content of each SSH

client public key, that are stored in a configuration file.

Figure 5 SSH public keys example

If a switch configuration contains multiple SSH client public keys, each public key is saved as a

separate entry in the configuration file. You can configure up to 10 SSH client public keys on a

switch.
