Configuring TCP/UDP Services

on the switch, usually for security reasons. The active TCP and UDP connections
are also displayed on the page.
To configure TCP/UDP services:
STEP 1 Click Security > TCP/UDP Services.
The TCP Service Table displays the following information for all active TCP
connections:
• Service Name—Address method through which the switch is offering the
TCP service.
• Type—IP protocol type that the service uses.
• Local IP Address—Local IP address through which the switch is offering the
service.
• Local Port—Local TCP port through which the switch is offering the service.
• Remote IP Address—IP address of the remote device that is requesting the
service.
• Remote Port—TCP port of the remote device that is requesting the service.
• State—The state of the service. The optional values are:
- ESTABLISHED—The socket has an established connection.
- SYN_SENT—The socket is actively attempting to establish a connection.
