Function

The mac-authen reauthenticate dhcp-renew command enables the device to re-authenticate the users when receiving DHCP lease renewal packets from MAC address authentication users.

The undo mac-authen reauthenticate dhcp-renew command restores the default setting.

By default, the device does not re-authenticate the users when receiving DHCP lease renewal packets from MAC address authentication users.

Format

In the system view:

mac-authen reauthenticate dhcp-renew interface { interface-type interface-number1 [ to interface-number2 ] } &<1-10>

undo mac-authen reauthenticate dhcp-renew interface { interface-type interface-number1 [ to interface-number2 ] } &<1-10>

In the interface view:

mac-authen reauthenticate dhcp-renew

undo mac-authen reauthenticate dhcp-renew

Parameters

Parameter	Description	Value
interface { interface-type interface-number1 [ to interface-number2 ] }	Specifies the type and number of an interface. interface-type specifies the interface type. interface-number1 specifies the number of the first interface. interface-number2 specifies the number of the last interface. The value of interface-number2 must be greater than the value of interface-number1. interface-number2 and interface-number1 together specify an interface range.	-

Usage Guidelines

After users go online, the administrator may modify the users' authentication parameters or network access rights on the authentication server. To ensure user validity or update the users' network access rights in real time, you can run this command to enable the device to re-authenticate the users when receiving DHCP lease renewal packets from MAC address authentication users.

This function applies only to BNG scenarios.
