Configuring Authenticated Switch Access Managing Switch Security Configuring Authenticated Switch Access Setting up Authenticated Switch Access involves the following general steps: 1 Set Up the Authentication Servers. This procedure is described briefly in this chapter. See the “Managing Authentication Servers” chapter of the OmniSwitch AOS Release 8 Network Configuration Guide for complete details. 2 Set Up the Local User Database. Set up user information on the switch if user login or privilege information will be pulled from the switch. See Chapter 6, “Managing Switch User Accounts.” 3 Set Up the Management Interfaces. This procedure is described in “Setting Up Management Interfaces for ASA” on page 7-9. 4 Set Up Accounting. This step is optional and is described in “Configuring Accounting for ASA” on page 7-11. Additional configuration is required in order to set up the switch to communicate with external authentication servers. This configuration is briefly mentioned in this chapter and described in detail in the “Managing Authentication Servers” chapter of the OmniSwitch AOS Release 8 Network Configuration Guide. If you are using the local switch database to authenticate users, user accounts must be set up on the switch. Procedures for creating user accounts are described in this chapter. See Chapter 6, “Managing Switch User Accounts.” Note that by default: • Authenticated switch access is available only through the console port. • Users are authenticated through the console port via the local user database on the switch. These defaults provide “out-of-the-box” security at initial startup. Other management interfaces (Telnet, HTTP, etc.) must be specifically enabled before they can access the switch. A summary of the commands used for configuring ASA is given in the following table: Commands user aaa radius-server aaa ldap-server aaa tacacs+-server aaa authentication aaa accounting session Used for... Configuring the local user database on the switch. Setting up the switch to communicate with external RADIUS, LDAP or TACACS authentication servers. Configuring the management interface and specifying the servers and/or local user database to be used for the interface. Optional. Specifies servers to be used for accounting. page 7-6 OmniSwitch AOS Release 8 Switch Management Guide May 2014
Managing Switch Security Quick Steps for Setting Up ASA Quick Steps for Setting Up ASA 1 If the local user database is used for user login information, set up user accounts through the user command. In this example, user privileges are configured: -> user thomas password mypassword read-write all 2 If an external RADIUS or LDAP server is used for user login information, use the aaa radius-server or aaa tacacs+-server commands to configure the switch to communicate with these servers. For example: -> aaa radius-server rad1 host 10.10.1.2 timeout 3 For more information, see the “Managing Authentication Servers” chapter in the OmniSwitch AOS Release 8 Network Configuration Guide. 3 Use the aaa authentication command to specify the management interface through which switch access is permitted (such as console, telnet, ftp, http, or ssh). Specify the server and backup servers to be used for checking user login and privilege information. Multiple servers of different types may be specified. For example: -> aaa authentication telnet rad1 ldap2 local The order of the server names is important. The switch uses the first available server in the list. In this example, the switch would use rad1 to authenticate Telnet users. If rad1 becomes unavailable, the switch will use ldap2. If ldap2 then becomes unavailable, the switch will use the local user database to authenticate users. 4 Repeat step 3 for each management interface to which you want to configure access; or use the default keyword to specify access for all interfaces for which access is not specifically denied. For example, if you want to configure access for all management interfaces except HTTP, you would enter: -> no aaa authentication http -> aaa authentication default rad1 local Note the following: • SNMP access may only use LDAP servers or the local user database. If you configure the default management access with only RADIUS SNMP will not be enabled. • It is recommended that Telnet and FTP be disabled if Secure Shell (ssh) is enabled. • If you want to use WebView to manage the switch, make sure HTTP is enabled. 5 Specify an accounting server if a RADIUS or LDAP server will be used for accounting. Specify local if accounting may be done on the switch through the Switch Logging feature. Multiple servers may be specified as backups. -> aaa accounting session ldap2 local OmniSwitch AOS Release 8 Switch Management Guide May 2014 page 7-7
