Description
Configure BGP protocol-level tracing options. To specify more than one tracing operation, include multiple flag statements.
The traceoptions statement is not supported
on QFabric systems.
Default
The default BGP protocol-level tracing options are
inherited from the routing protocols traceoptions statement
included at the [edit routing-options] hierarchy level.
The default group-level trace options are inherited from the BGP protocol-level traceoptions statement. The default peer-level trace options
are inherited from the group-level traceoptions statement.
Options
disable—(Optional) Disable
the tracing operation. You can use this option to disable a single
operation when you have defined a broad group of tracing operations,
such as all.
file name—Name of the
file to receive the output of the tracing operation. Enclose the name
within quotation marks. All files are placed in the directory /var/log. We recommend that you place BGP tracing
output in the file bgp-log.
files number—(Optional)
Maximum number of trace files. When a trace file named trace-file.0 reaches its maximum
size, it is renamed trace-file.0, then trace-file.1, and so on, until the maximum number of trace
files is reached. Then, the oldest trace file is overwritten. If you
specify a maximum number of files, you must also specify a maximum
file size with the size option.
Range: 2 through 1000 files
Default: 10 files
flag—Tracing operation
to perform. To specify more than one tracing operation, include multiple flag statements.
BGP Tracing Flags
-
4byte-as—4-byte AS events. -
bfd—BFD protocol events. -
damping—Damping operations. -
graceful-restart—Graceful restart events. -
ipsec—Events related to IPsec support for BGP peers when the IPsec is configured. -
keepalive—BGP keepalive messages. If you enable the the BGPupdateflag only, received keepalive messages do not generate a trace message. -
nsr-synchronization—Nonstop routing synchronization events. -
open—Open packets. These packets are sent between peers when they are establishing a connection. -
packets—All BGP protocol packets. -
refresh—BGP refresh packets. -
update—Update packets. These packets provide routing updates to BGP systems. If you enable only this flag, received keepalive messages do not generate a trace message. Use thekeepaliveflag to generate a trace message for keepalive messages.
Global Tracing Flags
all—All tracing operationsgeneral—A combination of thenormalandroutetrace operationsnormal—All normal operations
Default: If you do not specify this option, only unusual or abnormal operations are traced.
policy—Policy operations and actionsroute—Routing table changesstate—State transitionstask—Routing protocol task processingtimer—Routing protocol timer processing
flag-modifier—(Optional)
Modifier for the tracing flag. You can specify one or more of these
modifiers:
detail—Provide detailed trace information.filter—Provide filter trace information. Applies only toroute,damping, andupdatetracing flags.receive—Trace the packets being received.send—Trace the packets being transmitted.
no-world-readable—(Optional) Prevent any user
from reading the log file.
size size—(Optional) Maximum
size of each trace file, in kilobytes (KB), megabytes (MB),
or gigabytes (GB). When a trace file named trace-file reaches this size, it is renamed trace-file.0. When the trace-file again reaches its
maximum size, trace-file.0 is renamed trace-file.1 and trace-file is renamed trace-file.0. This renaming scheme continues until the maximum number of trace
files is reached. Then, the oldest trace file is overwritten. If you
specify a maximum file size, you also must specify a maximum number
of trace files with the files option.
Syntax:
xkto specify KB,xmto specify MB, orxgto specify GB
Range: 10 KB through the maximum file size supported on your system
Default: 128 KB
world-readable—(Optional) Allow any user to
read the log file.
Required Privilege Level
routing and trace—To view this statement in the configuration.
routing-control and trace-control—To add this statement to the configuration.
