Using the traceroute monitor Command

To display real-time monitoring information about each router between the Services Router and a specified destination host, enter the traceroute monitor command with the following syntax. Table 110 describes the traceroute monitor command options.

user@host> traceroute monitor host <count number> <inet | inet6>
<interval seconds> <no-resolve>
<size bytes><source source-address>
<summary>

To quit the traceroute monitor command, press Q.

Table 110: CLI traceroute monitor Command Options

Option	Description
host	Sends traceroute packets to the hostname or IP address you specify.
count number	(Optional) Limits the number of ping requests, in packets, to send in summary mode. If you do not specify a count, ping requests are continuously sent until you press Q.
inet	(Optional) Forces the traceroute packets to an IPv4 destination.
inet6	(Optional) Forces the traceroute packets to an IPv6 destination.
interval seconds	(Optional) Sets the interval between ping requests, in seconds. The default value is 1 second.
no-resolve	(Optional) Suppresses the display of the hostnames of the hops along the path.
size bytes	(Optional) Sets the size of the ping request packet. The size can be from 0 through 65468 bytes. The default packet size is 64 bytes.
source address	(Optional) Uses the source address that you specify, in the traceroute packet.
summary	(Optional) Displays the summary traceroute information.

Following is sample output from a traceroute monitor command:
