Network requirements
As shown in Figure 22 , three administrators need to access the switch for switch management: one
through a console port, one through an IP network, and one through a PSTN.
Configure the switch to:
• Perform no authentication for users who log in through the console port.
• Perform password authentication for users who log in through the IP network.
• Use the RADIUS server to authenticate users who log in through the PSTN, and use local
authentication as the backup.
• Assign different command levels to different types of users.
