In configurations with dynamic PPPoE subinterfaces over static PPPoE major interfaces, you can configure dynamic encapsulation type lockout for the PPPoE clients associated with a dynamic PPPoE subinterface column. Using this feature enables you to temporarily prevent the static PPPoE major interface from autodetecting, accepting, and creating dynamic PPPoE subinterface columns for a configurable time period.
By default, encapsulation type lockout is disabled for PPPoE clients. To configure a lockout time range for the PPPoE clients associated with the dynamic PPPoE subinterface columns on the PPPoE major interface, use the pppoe auto-configure command with the lockout-time keyword. You can also use the show pppoe interface lockout-time command to display detailed information about the current lockout condition for each PPPoE client, and the pppoe clear lockout interface command to clear (reset) the lockout condition for an individual PPPoE client.
For illustrations of the interface stacking in dynamic PPPoE over static PPPoE configurations, see Figure 42, Figure 43, Figure 44, and Figure 45.
