DescriptionField
IP Control Protocol (IPCP) state. The seven possible
states that may be displayed are as follows:
• Initial—Lower layer is unavailable (Down), and
no Open has occurred. The Restart timer is not
running in the Initial state.
• Starting—An administrative Open has been
initiated, but the lower layer is still unavailable
(Down). The Restart timer is not running in the
Starting state. When the lower layer becomes
available (Up), a Configure-Request is sent.
• Closed— IPCP is not currently trying to
negotiate.
• Stopped—A Terminate-Request has been sent
and the Restart timer is running, but a
Terminate-Ack has not yet been received.
• Closing—A Terminate-Request has been sent
and the Restart timer is running, but a
Terminate-Ack has not yet been received. Upon
reception of a Terminate-Ack, the Closed state
is entered. Upon the expiration of the Restart
timer, a new Terminate-Request is transmitted,
and the Restart timer is restarted. After the
Restart timer has expired Max-Terminate times,
the Closed state is entered.
• Stopping—A Terminate-Request has been sent
and the Restart timer is running, but a IPCP-Ack
has not yet been received. Req-Sent.
• ACKsent—IPCP has received a request and has
replied to it.
• ACKrcvd—IPCP has received a reply to a
request it sent.
• Open—IPCP is functioning properly.
