ppp log
Copyright © 2010, Juniper Networks, Inc.
Use to configure a trace log file for a PPP interface.
Specify one of the following interface types and an interface specifier. For example,
specify slot/port:channel/subchannel for a serial POS PPP interface.
serial—Serial interface
atm—ATM interface
pos—Packet over SONET interface
You also configure logging to direct the output to a specific destination. For information,
see Overview of System Logging.
Example
host1(config-if)#log severity debug pppPacket serial 0/0:1/1
DEBUG 01/01/1970 00:16:58 pppPacket (1000001,*): interface:0/0:1/11/0:1,
time: 0.00, tx lcp confReq, id = 226, length = 19, mru = 32759,
authentication = chap MD5,magicNumber = 0x5387f9a2
DEBUG 01/01/1970 00:16:58 pppPacket (1000001,*): interface: 0/0:1/11/0:1,
time: 0.01, rx lcp confReq, id = 156, length = 18, mru = 32759,
magicNumber = 0x2d8eac91, pfc, acfc
DEBUG 01/01/1970 00:16:58 pppPacket (1000001,*): interface: 0/0:1/11/0:1,
time: 0.01, tx lcp confAck, id = 156, length = 18, mru = 32759,

Use the no version to return the severity changes to their default setting or to the
systemwide setting.
See log severity.
Use to enable PPP packet or state machine logging on any dynamic interface that uses
the profile being configured. Specify one of the following keywords:
pppPacket—Enables PPP packet logging
pppStateMachine—Enables PPP state machine logging
Example
host1(config-profile)#ppp log pppPacket
NOTE: This command is equivalent to the log severity debug pppPacket
and log severity debug pppStateMachine commands.
Use the no version to disable packet or state machine logging.
See ppp log.
