You can optionally configure the following characteristics of the trace log file for a Virtual
Chassis:
Maximum number of trace files—When a trace file named

number of trace files is reached. Then the oldest trace file is overwritten. You can
optionally specify the maximum number of trace files to be from 2 through 1000. If
you specify a maximum number of files with the

Maximum trace file size—You can configure the maximum trace file size to be from 10
KB through 1 gigabyte (GB) If you specify a maximum file size with the

Timestamp—By default, timestamp information is placed at the beginning of each line
of trace output. You can optionally prevent placement of a timestamp on any trace
log file.
Appending or replacing the trace file—By default, the router or switch appends new
information to an existing trace file. You can optionally specify that the router or switch
replace an exisiting trace file instead of appending information to it.
To configure the maximum number and maximum size of trace files:
On the router or switch to be designated as the master of the Virtual Chassis, specify
the maximum number and maximum size of the trace file.
[edit virtual-chassis]
user@host# set traceoptions file filename files number size maximum-file-size
For example, to set the maximum number of files to 20 and the maximum file size to
2 MB for a trace file named
[edit virtual-chassis]
user@host# set traceoptions file vccp files 20 size 2097152
When the trace file for this example reaches 2 MB,

To prevent the router or switch from the placing a timestamp on the trace log file:
