NEAT configuration issue

Hi,

I´m currently setting a LAB in order to test NEAT feature. The Supplicant switch (sSW) is able to authenticate toward the Authenticator Switch (aSW).

sSW#sh cisp summary

CISP is running on the following interface(s):

----------------------------------------------

  Fa0/8 (supplicant)

When I connect a PC with X.509 certificate to the sSW, I see the EAPOL request coming from the PC to the sSW on Fa0/1:

*Mar  6 23:25:12.600: dot1x-ev(Fa0/1): Role determination not required

*Mar  6 23:25:12.600: dot1x-ev(Fa0/1): New client detected, issuing Start Request to AuthMgr

But the sSW does not forward the packet to the aSW.

sSW#sh cisp interface fastEthernet 0/1

CISP not enabled on specified interface

Do I need additional configuration on the port toward the PC?

Why the CISP is not enabled on the Fa0/1?

Topology and config is below:

Hi Amin,

Please have a look on the brief of CISP:

http://tools.cisco.com/ITDIT/CFN/Dispatch?act=featdesc&task=display&featureId=9434

In my understanding, the CISP is only working on the switch to switch port.

----------

Which can win the race: increasing bandwidth with new technologies VS QoS?

-- Best Regards

Hi,

When using neat the switch authenticates itself to the upstream switch so that the link becomes a trunking port. The switch that the client is connecting to must have the radius configuration to support dot1x much like your other switches. That switch that authenticates itself must have its ip address added to the radius server database so it can authenticate.

Let me know if that helps point you in the right direction.
