Configuring Secure Shell (SSH)
Terminology
6-4
PEM (Privacy Enhanced Mode): Refers to an ASCII-formatted
■
client public-key that has been encoded for portability and efficiency.
SSHv2 client public-keys are typically stored in the PEM format. See
figures 6-3 and 6-4 for examples of PEM-encoded ASCII and non-
encoded ASCII keys.
Private Key: An internally generated key used in the authentication
■
process. A private key generated by the switch is not accessible for
viewing or copying. A private key generated by an SSH client applica­
tion is typically stored in a file on the client device and, together with
its public key counterpart, can be copied and stored on multiple
devices.
Public Key: An internally generated counterpart to a private key. A
■
device's public key is used to authenticate the device to other devices.
Enable Level: Manager privileges on the switch.
■
■ Login Level: Operator privileges on the switch.
■ Local password or username: A Manager-level or Operator-level
password configured in the switch.
SSH Enabled: (1) A public/private key pair has been generated on
■
the switch (crypto key generate ssh [rsa]) and (2) SSH is enabled (ip
ssh). (You can generate a key pair without enabling SSH, but you
cannot enable SSH without first generating a key pair. See "2. Gener­
ating the Switch's Public and Private Key Pair" on page 6-10 and "4.
Enabling SSH on the Switch and Anticipating SSH Client Contact
Behavior" on page 6-15.)
