25.1.4 Configuring Passwords
The RS provides password authentication for accessing the User and Enable modes. If TACACS, TACACS+, or
RADIUS is not enabled on the RS, only local password authentication is performed.
To configure RS passwords, enter the following commands in Configure mode:
25.1.5 Configuring SSH
Secure shell (SSH) is a protocol that allows you to log in to a remote RS and execute commands on that router. SSH
provides more secure communications than using Telnet, as connections are authenticated and communications over
the network are encrypted.
The RS provides both an SSH server and client. Both server and client support SSH version 1. Only username and
password authentication (as configured with the CLI
system set password
command) is supported. If TACACS
or RADIUS authentication is enabled on the router, passwords are authenticated by the TACACS or RADIUS server.
Private and public keys on a per-user basis are not supported.
Establishing SSH Sessions
The SSH server on the RS must have a public key and a host key generated with the CLI
ssh server generate-key
command. The keys are generated using the Rivest-Shamir-Adleman (RSA) algorithm. For example, the following
command generates RSA keys on the router ‘r1’:
On the RS, you use the
slogin
command in Enable mode to access a remote RS SSH server. In addition to specifying
the hostname or host IP address of the RS, you can specify a username. The default username is
root
. You can
optionally specify a port number on the router; the default port number is 22. For example, the following command
allows you to log into the remote router ‘r1’ with the username ‘login’:
Set User mode password.
system set password login
VWULQJ!
Set Enable mode password.
system set password enable
VWULQJ!
