Release Information

Command introduced in JUNOS Release 8.0

Description

Displays live monitoring of each hop in the route packets take to a specified network host. Use traceroute monitor as a debugging tool to locate points of failure in a network.

Options

host — IP address or name of remote host.

count value — Number of ping requests, in packets, to send in summary mode. The default value is 10.

inet | inet6 — (Optional) Trace the route belonging to IPv4 or IPv6, respectively.

interval seconds — (Optional) Number of seconds to wait before sending ping requests. The default value is 1.

no resolve — (Optional) Do not attempt to display addresses symbolically.

size value — (Optional) Receive the specified number of bytes for each packet. The range is 0 through 65468 bytes. The default value is 64.

source source-address — (Optional) Source address of the outgoing ping packets.

summary — (Optional) Generate and display summary of live monitoring of each hop the route packets take to a specified network host.

Table 32 describes the output fields for the traceroute monitor command. Output fields are listed in the approximate order in which they appear.

Table 32: traceroute monitor Output Fields

Field Name	Field Description
Host	Hostname or IP address of the router at each hop.
Loss%	Percent of packet loss. The number of ping responses divided by the number of ping requests, specified as a percentage.
Snt	Number of ping requests sent to the router at this hop.
Last	Most recent round-trip time, in milliseconds, to the router at this hop.
Avg	Average round-trip time, in milliseconds, to the router at this hop.
Best	Shortest round-trip time, in milliseconds, to the router at this hop.
Wrst	Longest round-trip time, in milliseconds, to the router at this hop.
StDev	Standard deviation of round-trip times, in milliseconds, to the router at this hop.
