7.6.1.0 Introduced on the C-Series and S-Series.
7.4.1.0 Introduced on the E-Series.
Usage
Information
When you configure the dot1x server-timeout value, take into account the communication medium
used to communicate with an authentication server and the number of RADIUS servers configured.
Ideally, the dot1x server-timeout value (in seconds) is based on the configured RADIUS-server
timeout and retransmit values and calculated according to the following formula: dot1x server-
timeout seconds > (radius-server retransmit seconds + 1) * radius-server timeout seconds.
Where the default values are as follows: dot1x server-timeout (30 seconds), radius-server
retransmit (3 seconds), and radius-server timeout (5 seconds).
For example:
Dell(conf)#radius-server host 10.11.197.105 timeout 6
Dell(conf)#radius-server host 10.11.197.105 retransmit 4
Dell(conf)#interface tengigabitethernet 2/23
Dell(conf-if-te-2/23)#dot1x server-timeout 40
Use this command in Interface Batch Mode to configure the server time-out in a dual-homing setup.

Usage
Information
The dot1x static-mab command enables static MAB (mac auth bypass) and configures the
associated profile on a dot1x interface. Static MAB bypasses the authentication server for the supplicant
MAC addresses configured in the associated profile.
Before you enable static MAB, you must do the following:
● Enable MAC authentication bypass on the port by configuring the dot1x mac-auth-bypass
command.
● Ensure that no configured profile exists at the time of configuring the static-mab command.
● Use this command in Interface Batch Mode to enable static MAB in a dual-homing setup.
