IBM SC30-3681-08 manual Authenticate, Terminate, Link is being shut down, LCP State

Monitoring PPP Interfaces (Talk 5)

LCP The link is in LCP negotiation. This state occurs when ®rst bringing up an interface. The interface may be in self-test at this time.

Authenticate

The link is performing initial authentication.

ECP The link is negotiating an ECP encryption algorithm.

Note: Encryption support is optional. If your software load

does not include encryption, you will not see encryption-related parameters.

Ready Link is operating normally. NCPs can negotiate and data traffic associated with can ¯ow after successful NCP negotiation.

Terminate

The link is being shut down.

LCP State

Displays the current state of the point-to-point link. These states include the following:

OPEN - Indicates that a connection has been made and data can be sent. The retry timer does not run in this state.

CLOSED - Indicates that the link is down and no attempt is being made to open it. In this state, all connection requests from peers are rejected.

LISTEN - Indicates that the link is down and no attempt is being made to open it. In contrast to the CLOSED state, however, all connection requests from peers are accepted.

REQUEST-SENT - Indicates that an active attempt is being made to open the link. A Con®gure-request packet has been sent but a Con®gure-Ack has not yet been received nor has one been sent. The retry timer is running at this time.

ACK-RECEIVED - Indicates that a Con®gure-request packet has been sent and a Con®gure-Ack packet has been received. The retry timer is still running since a Con®gure-Ack packet has not been transmitted.

ACK-SENT - Indicates that a Con®gure-Ack packet and a Con®gure-request packet have been sent but a Con®gure-Ack packet has not been received. The retry timer always runs in this state.

CLOSING - Indicates that an attempt is being made to close the connection. A Terminate-request packet has been sent but a Terminate-Ack packet has not been received. The retry timer is running in this state.

Previous State

Displays the state of the point-to-point link prior to the state displayed in the Current state ®eld. These states are the same as those described in the Current state ®eld.

Time since change

Displays the amount of time that has elapsed since the last link state change.
