### About DPA - Remote

Use this topic to learn more about the Digi Port Authority - Remote (DPA - Remote) monitor.

#### DPA - Remote Description

DPA - Remote is a program to monitor data and errors on network interfaces and ports via SNMP agents over TCP/IP. A network interface to a device might be an Ethernet or PPP connection.

#### Network Interface Monitoring

Monitoring a network interface can be helpful in troubleshooting network performance issues, or just keeping track of the network interface performance. DPA - Remote can monitor incoming and outgoing data and errors on a network interface.

#### Port Monitoring

Monitoring ports can be helpful in troubleshooting port problems. DPA - Remote can monitor incoming and outgoing data and errors on ports. Also, individual signals (such as DTR, DCD, OFC, IFC, etc.) can be monitored. By viewing port signals, a user may be able to determine if a port appears to be functioning correctly, or if it appears to be in some state of flow control or other condition of concern.
