How to enable Mac-Auth-Bypass on nexus 3172TQ

[OrionPoplawski5828]

I've got a Nexus 3172TQ that I want to be able to enable 802.1x Mac-Auth-Bypass on but having no luck figuring it out.

Software
  BIOS: version 5.3.1
  NXOS: version 7.0(3)I7(7)
  BIOS compile time:  05/17/2019
  NXOS image file is: bootflash:///nxos.7.0.3.I7.7.bin
  NXOS compile time:  8/28/2019 16:00:00 [08/29/2019 00:41:42]


Hardware
  cisco Nexus 3172T Chassis

# show dot1x all
           Sysauthcontrol Enabled
   Dot1x Protocol Version 2

Dot1x Info for Ethernet1/17
-----------------------------------
                      PAE = AUTHENTICATOR
              PortControl = AUTO
                 HostMode = MULTI HOST
         ReAuthentication = Disabled
              QuietPeriod = 60
            ServerTimeout = 30
              SuppTimeout = 30
             ReAuthPeriod = 3600 (Locally configured)
                ReAuthMax = 2
                   MaxReq = 2
                 TxPeriod = 30
          RateLimitPeriod = 0
          Mac-Auth-Bypass = Disabled

Perhaps this version doesn't support MAB?

Hi,

   Try using command "dot1x mac-auth-bypass".

It took that.  Thanks.  I guess I got too hung up on the ? command help not showing that as an option:

(config-if)# dot1x ?
  default            Configure Dot1x with default values for this port
  host-mode          Role of 802.1x authenticating entity
  max-reauth-req     Maximum Re-authentication Attempts Before Failing
  max-req            Maximum Retries to Initiate Authentication
  pae                Role of 802.1x authenticating entity
  port-control       Port control
  re-authentication  Enable or Disable Reauthentication for this port
  timeout            Various Timeouts

Did you finally managed it? I have a Cisco Nexu 3048 with Firmware 7 and also not found that command under dot1x
