運行CatOS軟體的Catalyst 6500/6000的IEEE 802.1x身份驗證配置示例

Console (enable) set system name Cat6K 
System name set.

!--- Sets the hostname for the switch.

Cat6K> (enable) set localuser user admin password cisco
Added local user admin.
Cat6K> (enable) set localuser authentication enable
LocalUser authentication enabled

!--- Uses local user authentication to access the switch.

Cat6K> (enable) set vtp domain cisco
VTP domain cisco modified

!--- Domain name must be configured for VLAN configuration.

Cat6K> (enable) set vlan 2 name VLAN2
VTP advertisements transmitting temporarily stopped,
and will resume after the command finishes.
Vlan 2 configuration successful

!--- VLAN should be existing in the switch !--- for a successsful authentication.

Cat6K> (enable) set vlan 3 name VLAN3
VTP advertisements transmitting temporarily stopped,
and will resume after the command finishes.
Vlan 3 configuration successful

!--- VLAN names will be used in RADIUS server for VLAN assignment.

Cat6K> (enable) set vlan 4 name AUTHFAIL_VLAN
VTP advertisements transmitting temporarily stopped,
and will resume after the command finishes.
Vlan 4 configuration successful

!--- A VLAN for non-802.1x capable hosts.

Cat6K> (enable) set vlan 5 name GUEST_VLAN
VTP advertisements transmitting temporarily stopped,
and will resume after the command finishes.
Vlan 4 configuration successful

!--- A VLAN for failed authentication hosts.

Cat6K> (enable) set vlan 10 name RADIUS_SERVER
VTP advertisements transmitting temporarily stopped,
and will resume after the command finishes.
Vlan 10 configuration successful

!--- This is a dedicated VLAN for the RADIUS Server.

Cat6K> (enable) set interface sc0 10 172.16.1.2 255.255.255.0
Interface sc0 vlan set, IP address and netmask set.

!--- Note: 802.1x authentication always uses the !--- sc0 interface as the identifier for the authenticator !--- when communicating with the RADIUS server.

Cat6K> (enable) set vlan 10 3/1
VLAN 10 modified.
VLAN 1 modified.
VLAN  Mod/Ports
---- -----------------------
10    3/1

!--- Assigns port connecting to RADIUS server to VLAN 10.

Cat6K> (enable) set radius server 172.16.1.1 primary
172.16.1.1 with auth-port 1812 acct-port 1813 
added to radius server table as primary server.

!--- Sets the IP address of the RADIUS server.

Cat6K> (enable) set radius key cisco
Radius key set to cisco

!--- The key must match the key used on the RADIUS server.

Cat6K> (enable) set dot1x system-auth-control enable
dot1x system-auth-control enabled.
Configured RADIUS servers will be used for dot1x authentication.

!--- Globally enables 802.1x. !--- You must specify at least one RADIUS server before !--- you can enable 802.1x authentication on the switch.

Cat6K> (enable) set port dot1x 3/2-48 port-control auto
Port 3/2-48 dot1x port-control is set to auto.
Trunking disabled for port 3/2-48 due to Dot1x feature.
Spantree port fast start option enabled for port 3/2-48.

!--- Enables 802.1x on all FastEthernet ports. !--- This disables trunking and enables portfast automatically.

Cat6K> (enable) set port dot1x 3/2-48 auth-fail-vlan 4
Port 3/2-48 Auth Fail Vlan is set to 4

!--- Ports will be put in VLAN 4 after three !--- failed authentication attempts.

Cat6K> (enable) set port dot1x 3/2-48 guest-vlan 5
Ports 3/2-48 Guest Vlan is set to 5

!--- Any non-802.1x capable host connecting or 802.1x !--- capable host failing to respond to the username and password !--- authentication requests from the Authenticator is placed in the !--- guest VLAN after 60 seconds. !--- Note: An authentication failure VLAN is independent !--- of the guest VLAN. However, the guest VLAN can be the same !--- VLAN as the authentication failure VLAN. If you do not want to !--- differentiate between the non-802.1x capable hosts and the !--- authentication failed hosts, you can configure both hosts to !--- the same VLAN (either a guest VLAN or an authentication failure VLAN). !--- For more information, refer to !--- Understanding How 802.1x Authentication for the Guest VLAN Works.
