Release Information Statement introduced in Junos OS Release 9.0 for EX Series switches.
Description Define tracing operations for DHCP processes.
Options file filename—Name of the file that receives the output of the tracing operation. Enclose
the name in quotation marks. All files are placed in the directory /var/log.
files number—(Optional) Maximum number of trace files. When a trace file named
trace-file 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 also must specify a maximum file size with
the size option and a filename.
Range: 2 through 1000
Default: 3 files
