authentication succeeds, you will log in to the server. The level of commands that you can access after
login is authorized by the CAMS server. You can specify the level by setting the
EXEC Privilege Level

When Switch Acts as Server for Password and HWTACACS Authentication
Network requirements
As shown in
Figure 55-19
, an SSH connection is required between the host (SSH client) and the switch
(SSH server) for secure data exchange. Password and HWTACACS authentication is required.
z
The host runs SSH2.0 client software to establish a local connection with the switch.
z
The switch cooperates with an HWTACACS server to authenticate SSH users.

Configure the SSH server
# Create a VLAN interface on the switch and assign it an IP address. This address will be used as the IP
address of the SSH server for SSH connections.

Generating the RSA key pair on the server is prerequisite to SSH login.
# Generate RSA key pair.
[Switch] public-key local create rsa
# Set the authentication mode for the user interfaces to AAA.
