config 802.1x auth_parameter
Restrictions
Example usage:
To configure 802.1x authentication parameters for ports 1 – 20 of switch 1:
DES-6500
all − Specifies all of the ports on the switch.
default − Returns all of the ports in the specified range to their 802.1x
default settings.
direction [both|in] − Determines whether a controlled port blocks
communication in both the receiving and transmitting directions, or just
the receiving direction.
port_control − Configures the administrative control over the
authentication process for the range of ports.
force_auth − Forces the Authenticator for the port to become
authorized. Network access is allowed.
auto − Allows the port's status to reflect the outcome of the
authentication process.
force_unauth − Forces the Authenticator for the port to become
unauthorized. Network access will be blocked.
quiet_period <sec 0-65535> − Configures the time interval between
authentication failure and the start of a new authentication attempt.
tx_period <sec 1-65535> - Configures the time to wait for a response
from a supplicant (user) to send EAP Request/Identity packets.
supp_timeout <sec 1-65535> - Configures the time to wait for a
response from a supplicant (user) for all EAP packets, except for the
Request/Identity packets.
server_timeout <sec 1-65535> - Configure the length of time to wait for
a response from a Radius server.
max_req <value 1-10> − Configures the number of times to retry
sending packets to a supplicant (user).
reauth_period <sec 1-65535> − Configures the time interval between
successive re-authentications.
enable_reauth [enable|disable] − Determines whether or not the switch
will re-authenticate. Enabled causes re-authentication of users at the
time interval specified in the Re-authentication Period field, above.
Only administrator-level users can issue this command.
