Tracing Operations of the pppd Process

To trace the operations of the router’s pppd process, include the traceoptions statement at the [edit protocols ppp] hierarchy level:

[edit protocols ppp]traceoptions {file filename <files number> <match regular-expression> <size size> <world-readable | no-world-readable>;flag flag;level severity-level;no-remote-trace;}

To specify more than one tracing operation, include multiple flag statements.

You can specify the following flags in the traceoptions statement:

access—Access code
address-pool—Address pool code
all—All areas of code
auth—Authentication code
chap—Challenge Handshake Authentication Protocol (CHAP) code
config—Configuration code
ifdb—Interface database code
lcp—LCP state machine code
memory—Memory management code
message—Message processing code
ncp—NCP state machine code
pap—Password Authentication Protocol (PAP) code
ppp—PPP protocol processing code
radius—RADIUS processing code
rtsock—Routing socket code
session—Session management code
signal—Signal handling code
timer—Timer code
ui—User interface code
