Function

The radius-no-response lease-time command configures the device to deliver a lease for DHCP users when the RADIUS server does not respond after the authentication mode is set to RADIUS+NONE.

Usage Guidelines

Usage Scenario

If the authentication mode in an AAA domain is configured as RADIUS authentication + non-authentication, DHCP users can still go online when the RADIUS does not respond. However, when the RADIUS server is not responding, these users are not charged. To configure the device to deliver a lease for DHCP users, run the radius-no-response lease-time command. When the RADIUS server responds and a user attempts to update its lease, the device sends an NAK packet to the user. In this situation, the user is re-authenticated and charged.

Configuration Impact

The longer the lease configured using the radius-no-response lease-time command, the longer it takes for online DHCP users to be free of charge after the RADIUS server does not respond. DHCP users may log in and log out consecutively in a short period of time If the configured lease is too short.

Precautions

The radius-no-response lease-time command takes effect only for users who go online after the command is configured.

In VS mode, this command is supported only by the admin VS.

This command can not be used in RUI scenarios and disaster recovery scenarios.
