Administrator Guide

Usage Information
When you congure the dot1x server-timeout value, take into account the communication medium used to
communicate with an authentication server and the number of RADIUS servers congured. Ideally, the dot1x
server-timeout
value (in seconds) is based on the congured 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).
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 1/1/1/1
Dell(conf-if-te-1/1/1/1)# dot1x server-timeout 40
dot1x static-mab
Enable static MAC authorization bypass (MAB) and congure static MAB prole to an interface.

Version Description
9.10(0.0) Introduced on the S3100 series, S4048–ON, S4048–ON, S4810, S4820T, S5000, S6000,
S6000–ON, S6100–ON, the Conguration Terminal Batch mode on C9010, Z9100–ON,
and Z9500.
9.9(0.0) Introduced on the C9010.
Usage Information
The dot1x static-mab command enables static MAB (mac auth bypass) and congures the associated prole
on a dot1x interface. Static MAB bypasses the authentication server for the supplicant MAC addresses congured
in the associated prole.
Before you enable static MAB, you must do the following:
•
Enable MAC authentication bypass on the port by conguring the dot1x mac-auth-bypass command.
• Ensure that no congured prole exists at the time of conguring the static-mab command.
• Use this command in Interface Batch Mode to enable static MAB in a dual-homing setup.
Example
Dell(conf)#do show dot1x interface ten gigabit ethernet 0/41
