Table 4.3 Description of each parameter for Traceroute (IPv4)
Label
Description
Hostname or IP Address
Specifies the hostname or IP Address of the destination
DSCP Value
Specifies the DSCP (DiffServ Code Point) priority (value) in packets. The value is
an integer that has a range from 0 to 63.
Number of Probes Per Hop
Specifies the number of probe packets sent for each hop which is the number of
queries per intermediate host or gateway. The default value is 3 packets. The valid
range is 1 – 60.
Response Timeout
Specifies the timeout for the response message or ICMP echo reply after an ICMP
echo request message is sent to an intermediate host or gateway. This is the number
of seconds to wait for a reply to a sent request. The default number is 3. The valid
range is 1 – 86400.
First TTL Value
Specifies the initial Time to Live (TTL) value. This is a field in the IPv4 header in
the first packet sent. The default value is 1. The valid range is 1 – 30.
Max TTL Value
Specifies the maximum number of hops traceroute will try to probe. If this value is
reached before the specified remote host is reached, the test stops. The default
value is 30. The valid range is 1 – 255.
VID for source Interface
This field can be used to force the test to use a specific local VLAN interface as the
source interface. Leave this field empty for automatic selection based on routing
configuration.
Note: You may only specify either the VID or the IP Address for the source
interface.
IP Address for Source Interface
This field can be used to force the test to use a specific local interface with the
specified IP address as the source interface. The specified IP address must be
configured on a local interface. Leave this field empty for automatic selection
based on routing configuration.
Note: You may only specify either the VID or the IP Address for the source
interface.
Use ICMP instead of UDP
By default, the traceroute command will use UDP datagrams. Selecting this option
forces it to use ICMP ECHO packets instead.
Print Numeric Addresses
By default, the traceroute command will print out hop information using a reverse
DNS lookup for the acquired host IP addresses. This may slow down the display if
the DNS information is not available. Selecting this option will prevent the reverse
DNS lookup and force the traceroute command to print numeric IP addresses
instead.
