LCP State

Displays the current state of the point-to-point link. These states include the following:
Open A connection has been made and data can be sent. The retry timer does not run in this state. Closed The link is down and there is no attempt being made to open it. In this state, all connection requests from peers are rejected. Listen The link is down and there is no attempt being made to open it. In contrast to the Closed state, however, all connection requests from peers are accepted. Request-Sent An active attempt is being made to open the link. A Configure-request packet has been sent but a Configure-Ack has not yet been received nor has one been sent. The retry timer is running at this time. Ack-Received A Configure-request packet has been sent and a Configure-Ack packet has been received. The retry timer is still running since a Configure-Ack packet has not been transmitted. Ack-Sent A Configure-Ack packet and a Configure-request packet have been sent but a Configure-Ack packet has not been received. The retry timer always runs in this state.

Closing 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

The state of the point-to-point link prior to the state displayed in the LCP State field. These states are the same as those described in the LCP State field.

Time Since Change

Amount of time the link has been in the present state.

LCP Option

Max receive
unit

The maximum packet size set for both the local and remote end of the link.

Async
character
mask

Not applicable to the GlobeTrotter 70 or 72. PPP accepts this option but ignores it.

Authentication

PAP and CHAP currently supported.

Magic number

The current magic number for both the local and remote end of the link.

Protocol
Field Comp

Whether or not Protocol Field Compression (PFC) is enabled or disabled for both the local and remote ends of the link. If local PFC is Yes, this interface expects the protocol field to be compressed. If remote is Yes, this interface sends a compressed protocol field per the PPP RFC 1661 specification.

Addr/Cntl
compression

Whether or not Address/Control Field Compression (ACFC) is enabled or disabled for both the local and remote ends of the link. If local PFC is Yes, this interface expects the address/control field to be compressed. If remote is Yes, this interface sends a compressed address/control field per the PPP RFC 1661 specification.

32-bit
checksum

Not currently supported. PPP rejects this option.
