Looks like exactly what you asked, Kings:

ACS NAP has a profile created from a template profile - "Agentless Host for L2 
(802.1x fall back)
In the authentication section for this profile the router's MAC address is 
entered into the area "Authenticate MAC with"
ACS creates a record in the Reports -> "Passed Authentications" for this MAC 
address as successful with the associated shared Radius authorization profile.

The switch AAA config portion is as follows:

aaa new-model
aaa authentication login default none
aaa authentication dot1x default group radius
aaa authorization network default group radius
aaa accounting dot1x default start-stop group radius
dot1x system-auth-control

interface FastEthernet0/2   //this is where the router is connected
switchport mode access
authentication order dot1x mab webauth
authentication port-control auto
mab
dot1x pae authenticator
dot1x max-reauth-req 1

radius-server host 10.0.0.100 auth-port 1645 acct-port 1646 key CISCO
radius-server vsa send authentication

Subject: Re: [OSL | CCIE_Security] MAB with 802.1x

Is the MAC address configured in the ACS NAP configured for MAB?

Can you paste your AAA config.

With regards
Kings

Folks,
Anyone can give me a clue why the switch reports the status of the port 
configured for MAC authentication bypass as "UNAUTHORIZED" ?
Based on the output below the authorization session succeeded but the summary 
for dot1x says it is unauthorized. Is it expected ?
