# ppp ipcp lockout

#### Syntax

[ no ] ppp ipcp lockout

#### Release Information

Command introduced in JunosE Release 11.0.0.

#### Description

Terminates invalid IPv4 subscribers and prevents additional IPCP negotiations. The subscriber can negotiate IPv4 addresses, IPv6 addresses, or both. When Internet Protocol version 6 Control Protocol (IPv6CP) is active, this command enables unused IPv4 addresses, which are allocated for the IPv6 subscribers, to be available for the IPCP services for an internally defined time interval (10 seconds). When the time interval elapses, the subscriber must connect again to negotiate IPCP. The no version disables the lockout option.

#### Mode

Interface Configuration, Profile Configuration, Subinterface Configuration
