The Introduction To Debugging Instruments - UTStarcom iSpirit 3026 Manual

17.1 The Introduction to Debugging Instruments

iSpirit 3026 switch supply with several kinds of debugging instruments, such as: IP DEBUG
instruments, PING instruments, TRACEROUTE instruments and TELNET instruments in the
end of client.
In this chapter we will describe the using and configure of these instruments in detail, the main
content is as follows::
● introduction to IP DEBUG instruments
● introduction to PING instruments
● introduction to TRACEROUTE instruments introduction to
● introduction to TELNET instruments in the end of client
1. Introduction to IP DEBUG Instrument
IP DEBUG instrument is used to display the basic information of the data flow received and sent
by the switch in the terminal and to capture the basic information of ARP data flow.
If there is relevant thing happed or data flow received and sent, it will display the information
through the relevant command configured in the terminal, so we can debug and diagram the
malfunction and problems of the switch and internet.
Through these IP DEBUG command, the manager can affirm whether the switch has received or
sent the protocol packet. It will display some relevant information such as TCP protocol packet,
TCP purpose port and resource port, and so on.
iSpirit 3026 switch support a serial end and 5 TELNET end. And all of these ends can configure
with IP DEBUG command. When a end open the DEBUG configure, the relevant information will
be displayed in this end, but not affecting another ends. if a end A open the ARP DEBUG, the
other end B open TCP DEBUG, the information of ARP will be displayed in end A, and the
information of TCP will be displayed in end B. if two or more ends open the same DEBUG, the
relevant debug information will be displayed in all opened ends. For example, the end A and end
B will display ARP DEBUG, the ARP configures information will displayed in end A and end B.
When you open DEBUG, the performance of the switch will be affected, especially for the
performance of receiving and sending. So we advice the user open the DEBUG only when
diagnosis for the switch and Internet, when finished please close all DEBUG.
