• The CLI is accessible from remote telnet through the IP address for the
switch. IP addresses are assigned separately for the service port and the in-
band ports.
• The CLI is accessible from a secure shell interface.
• The CLI generates keys for SSH locally.
• The serial session defaults to 9600 baud rate, eight data bits, non-parity
and one stop bit.
User Accounts Management
The CLI provides authentication for users either through remote
authentication servers supporting TACACS+ or Radius or through a set of
locally managed user accounts. The setup wizard asks the user to create the
initial administrator account and password at the time the system is booted.
The following rules and specifications apply:
• The user may create five local user accounts.
• User accounts have an access level, a user name, and a user password.
• The user is able to delete the user accounts but the user will not be able to
delete the last level 15 account.
• The user password is saved internally in encrypted format and never
appears in clear text anywhere on the CLI.
• The CLI supports TACACS+ and Radius authentication servers.
• The CLI allows the user to configure primary and secondary
authentication servers. If the primary authentication server fails to respond
within a configurable period, the CLI automatically tries the secondary
authentication server.
• The user can specify whether the CLI should revert to using local user
accounts when the remote authentication servers do not respond or if the
CLI simply fails the login attempt because the authentication servers are
down. This requirement applies only when the user is logged in through a
telnet or an SSH session.
• The CLI always allows the user to log in to a local serial port even if the
remote authentication server(s) are down. In this case, CLI reverts to using
the locally configured accounts to allow the user to log in.
