Table 193 summarizes
the output in the traceroute display. If the device receives
no responses from the destination host, review the list after Table 193 for a possible
explanation.
Table 193: J-Web Traceroute
Results and Output Summary
Field
Description
hop-number
Number of the hop (router) along the path.
host
Hostname, if available, or IP address of the router. If the
Don't Resolve Addresses check box is selected, the hostname is not
displayed.
ip-address
IP address of the router.
as-number
AS number of the router.
time1
Round-trip time between the sending of the first traceroute
packet and the receiving of the corresponding Time Exceeded packet
from that particular router.
time2
Round-trip time between the sending of the second traceroute
packet and the receiving of the corresponding Time Exceeded packet
from that particular router.
time3
Round-trip time between the sending of the third traceroute
packet and the receiving of the corresponding Time Exceeded packet
from that particular router.
If the device does not display the complete path
to the destination host, one of the following explanations might apply:
The host is not operational.
There are network connectivity problems between the device and
the host.
The host, or a router along the path, might be configured
to ignore ICMP traceroute messages.
The host, or a router along the path, might be configured
with a firewall filter that blocks ICMP traceroute requests or ICMP
time exceeded responses.
The value you selected in the Time Exceeded box was less
than the number of hops in the path to the host. In this case, the
host might reply with an ICMP error message.
For more information about ICMP, see RFC 792, Internet Control Message Protocol.
