Tracing ES-IS Protocol Traffic

To debug ES-IS protocol or trace ES-IS protocol traffic, you can specify options in the global traceoptions statement included at the [edit routing-options] hierarchy level, and you can specify ES-IS–specific options by including the traceoptions statement:




traceoptions {
file filename <files number> <size size> <world-readable |
no-world-readable>;
flag flag <flag-modifier> <disable>;
}

For a list of hierarchy levels at which you can include this statement, see the statement summary section for this statement.

You can specify the following ES-IS–specific trace options in the ES-IS flag statement:

all—Everything
error—Errored packets
esh—End-system hello packets
general—General events
graceful-restart—Graceful restart events
ish—Intermediate-System hello packets
normal—Normal events
policy—Policy processing
route—Routing information
state—State transitions
task—Routing protocol task processing
timer—Routing protocol timer processing

You can optionally specify one or more of the following flag modifiers:

detail—Detailed trace information
receive—Packets being received
send—Packets being transmitted

Note: Use the trace flags detail and all with caution. These flags may cause the CPU to become very busy.
