pppstat Command

Purpose

Extracts and displays the RAS (Reliability, Availability, and Serviceability) information of the PPP (Point to Point Protocol) subsystem. This command only applies to AIX 4.1.5.

Syntax

pppstat

Description

The pppstat command provides the capability to monitor particular characteristics of active links. The following information is displayed for all active links:

LCP Multiplexing Layer

Local MRU	Specifies the Maximum Receive Unit setting for this host. This is maximum length of a packet that the remote host can send to the local host.
Remote MRU	Specifies the Maximum Receive Unit setting for the remote host. This is the maximum length of a packet that we can send to the remote host.
Local To Peer ACCM	Specifies the ASYNC Character Map used in the transmission of packets to the remote host.
Peer To Local ACCM	Specifies the ASYNC Character Map used by the remote host in the transmission of packets to the local host.
Local To Remote Protocol Field Compression	Specifies whether Protocol Compression is used in the transmission of packets to the remote host.
Remote To Local Protocol Field Compression	Specifies whether Protocol Compression is used in the transmission of packets from the remote host to the local host.
Local To Remote Address/Control Field Compression	Specifies whether Address/Control field compression is being used in the transmission of packets to the remote host.
Remote To Local Address/Control Field Compression	Specifies whether Address/Control field compression is being used in the transmission of packets from the remote host to the local host.

LCP Multiplexing Layer prior to PPP negotiating

MRU	Specifies the Maximum Receive Unit for receiving packets. This is the value that this host attempted to negotiate with the remote host.
Receive ACCM	Specifies the initial remote-to-local ASYNC Character Map that was used in the negotiation.
Transmit ACCM	Specifies the initial local-to-remote ASYNC Character Map that was used in the negotiation.
Magic Number	Specifies the magic number attempted in negotiation.
Frame Check Size	Specifies the length of the Frame Check Sequence that this host attempted to negotiate. This is fixed at 16 bits.

HDLC Framing Layer

Bad Address Fields	Specifies the number of times a packet has been received with an incorrect address field.
Bad Controls Fields	Specifies the number of times a packet has been received with an incorrect control field.
Oversized Packets	Specifies the number of times a packet has been received that has a length that exceeds the Maximum Receive Unit length.
Bad Frame Check Sequence	Specifies the number of times a packet has been received with a bad Frame Check Sequence.
Incoming Good Octets	Specifies the number of octets received in valid packets.
Outgoing Good Octets	Specifies the number of octets sent successfully in packets.
Incoming Good Packets	Specifies the number of packets received successfully.
Outgoing Good Packets	Specifies the number of packets sent successfully.

The output is sent to stdout. Messages are sent to stderr.

Exit Status

This command returns the following exit values:
