Cisco TelePresence Administrator's Guide

A new section will appear with a banner stating the results of the trace, and showing the following information
for each router in the path:
TTL (Time to Live). This is the hop count of the request, showing the sequential number the router.
Response This shows the IP address of the router, and the time taken (in ms) to respond to each packet
received from the VCS.
*** indicates that the router did not respond to the request.
The route taken between the VCS and a particular host may vary for each traceroute request.
Tracepath
The Tracepath tool (Maintenance > Tools > Network utilities > Tracepath) can be used to assist in
troubleshooting system issues.
It allows you to discover the route taken by a network packet sent from the VCS to a particular destination
host system.
To use this tool:
1. In the Host field, enter the IP address or hostname of the host system to which you want to trace the
route.
2. Click Tracepath.
A new section will appear with a banner stating the results of the trace, and showing the details of each router
along the path, the time taken for each router to respond to the request, and the maximum transmission units
(MTU).
The route taken between the VCS and a particular host may vary for each tracepath request.
DNS lookup
The DNS lookup tool (Maintenance > Tools > Network utilities > DNS lookup) can be used to assist in
troubleshooting system issues.
It allows you to query DNS for a supplied hostname and display the results of the query if the lookup was
successful.
To use this tool:
1. In the Host field, enter either:
l the name of the host you want to query, or
l an IPv4 or IPv6 address if you want to perform a reverse DNS lookup
2. In the Query type field, select the type of record you want to search for:
(for reverse lookups the Query type is ignored - the search automatically looks for PTR records)
Option Searches for...
All any type of record
A (IPv4 address) a record that maps the hostname to the host's IPv4 address
