ONFIGURATION

The following commands are used for configuring the 802.1x timers.

Perform the following configurations in System View. 

Table 421   Configuring Timers

This timer begins after the user has passed the authentication. 

After setting handshake-period, system will send the handshake packet by the period. 
Suppose the dot1x retry time is configured as N, the system will consider the user 
having logged off and set the user as logoff state if system doesn't receive the 
response from user for consecutive N times.

: Handshake period. The value ranges from 1 to 1024 in 

units of second and defaults to 15.

: Specify the quiet timer. If an 802.1x user has not passed the 

authentication, the Authenticator will keep quiet for a while (which is specified by 

timer) before launching the authentication again. During the quiet 

period, the Authenticator does not do anything related to 802.1x authentication.

: Specify how long the quiet period is. The value ranges from 10 

to 120 in units of second and defaults to 60.

: Specify the timeout timer of an Authentication Server. If an 

Authentication Server has not responded before the specified period expires, the 
Authenticator will resend the authentication request.

: Specify how long the duration of a timeout timer of an 

Authentication Server is. The value ranges from 100 to 300 in units of second and 
defaults to 100.

: Specify the authentication timeout timer of a user. After the 

Authenticator sends a Request/Challenge request packet to request the MD5 
encrypted text, the supp-timeout timer of the Authenticator begins to run. If the user 
does not respond back successfully within the time range set by this timer, the 
Authenticator will resend the above packet.

: Specify how long the duration of an authentication timeout 

timer of a user is. The value ranges from 10 to 120 in units of second, and defaults to 
30.

: Specify the transmission timeout timer. After the Authenticator sends a 

Request/Identity request packet which requests the user name, or the user name and 
password together the tx-period timer of the Authenticator begins to run. If the user 
does not respond back successfully with an authentication reply packet, then the 
Authenticator will resend the authentication request packet.

: Specify how long the duration of the transmission timeout timer 

is. The value ranges from 10 to 120 in units of second, and defaults to 30.
