ISE (Identity Services Engine) Basic Configuration and Commands

Cisco Switch Dot1x Config:

Configuring Global AAA Parameters:

conf t
username admin privilege 15 secret Cisco123
aaa new-model
aaa authentication login default local
aaa authentication dot1x default group radius
aaa authorization network default group radius
aaa accounting dot1x default start-stop group radius

radius server Our-ISE

Switch Port Configuration:

conf t
vlan 10,20,30,80,999

int range fa 0/1-8
switchport host
switchport access vlan 999
authentication priority dot1x mab
authentication order dot1x mab
authentication event fail action next-method
authentication event server dead action authorise vlan 10
authentication event server alive action reinitialize
authentication host-mode multi-domain
authentication violation restrict
dot1x pae authenticator
dot1x timeout tx-period 5
authentication port-control auto


Verification and Troubleshooting:
show int status (to check vlans the interfaces are)
show vlan brief (to see if the vlan now exists and an authenticated port it assigned to it)
show authentication sessions
show authentication sessions int fa 0/1 (MAC/IP/user/status/DACL/success/failure)
