Port

Description

Activity

TCP(3)

514

Any

Used as a server to listen for requests asking to initiate

Logging(1)

 

 

 

activity logging. These requests are normally sent from the

 

 

 

 

activity logging client. Once a request is received and the

 

 

 

 

connection is established, the port is used as the source for

 

 

 

 

sending the activity logging data.

 

 

 

 

 

EASY CPU(1)

UDP(4)

4001

Any

Used to communicate (to the EASY CPU or any other such

 

 

 

 

program) all available status or information data. This port

 

 

 

 

works as a server where each received request produces

 

 

 

 

one or more replies to the requesting client (usually to the

 

 

 

 

EASY CPU).

 

 

 

 

 

Snapshot(1)

UDP(4)

Any

69

Used for sending JPEG images taken from a camera. Uses

 

 

 

 

TFTP (Trivial File Transfer Protocol) for image transfer.

 

 

 

 

 

Setting Time/

UDP(4)

69

Any

Used to set or retrieve MPCPU calendar time. Uses TFTP

Firmware

 

 

 

(Trivial File Transfer Protocol) for the calendar time data

Upgrade(1)

 

 

 

transfer.

NTP(2)

UDP(4)

123

123

NTP (Network Time Protocol) provides time synch between

 

 

 

 

the MPCPU and network systems.

 

 

 

 

 

Alarm Email(2)

TCP(3)

Any

25

This port of the server to which the MPCPU sends Email

 

 

 

 

messages in response to an alarm.

 

 

 

 

 

IP Address

UDP(4)

68

67

Port 68 (source) assigns the IP address and is used for

Assignment(2)

 

 

 

DHCP when enabled. Port 67 Bootstrap Protocol Server

 

 

 

 

(destination) is the listening port on boot and DHCP

 

 

 

 

servers. Clients broadcast to this port for boot or network

 

 

 

 

parameters.

 

 

 

 

 

Notes:

 

 

 

 

(1)MPCPU specific

(2)Network specified

(3)TCP (Transmission Control Protocol)

(4)UDP (User Datagram Protocol).
