Connect (TCP) Test
Purpose
The Connect (TCP) test performs a TCP port open to the selected
target to test for application port availability. The test verifies
basic application port connectivity using a 3-way handshake (SYN,
SYN/ACK, ACK). The test can be used to determine whether a
service is available. TCP port connectivity can be preferable to
ping testing because ping may be blocked or disabled on target
devices or their routes.
The target can be an IPv4 address, IPv6 address or named server.
The port parameter allows testing for specific application
availability on well-known system ports such as port 80 for HTTP
or private ports up to 65535. Visit
www.iana.org for complete list
of registered ports.
Configuration
Server - Enter the URL or the IP address of the target server. See
also: “Server” on page 84 .
Name - The Name button allows you to assign a custom name to
the test. See also: “Name” on page 84 .
Port - Specify the TCP port number on which the TCP connection
will be established.
Time Limit - Set the amount of time allowed for the TCP
connection to be established.
The wired IPv4 and wired IPv6 tests run simultaneously.
Count - This is the number of times the TCP connection will be
established. If Continuous is selected the Time Limit will be
ignored.
In Continuous mode, the analyzer will establish the TCP
connection over the wired Ethernet connection if available.
