EDR-G903/G902 Features and Functions

Using Diagnosis
The EtherDevice Router provides Ping tools and LLDP for administrators to diagnose network systems.
Ping
The Ping function uses the ping command to give users a simple but powerful tool for troubleshooting network
problems. The function’s most unique feature is that even though the ping command is entered from the user’s
PC keyboard, the actual ping command originates from the EtherDevice Router itself. In this way, the user can
essentially control the EtherDevice Router and send ping commands out through its ports. There are two basic
steps required to set up the Ping command to test network integrity:
1. Select which interface will be used to send the ping commands. You may choose from WAN1, WAN2, and
LAN.
2. Type in the desired IP address, and click Ping.
LLDP Function Overview
Defined by IEEE 802.11AB, Link Layer Discovery Protocol (LLDP) is an OSI Layer 2 Protocol that standardizes
the methodology of self-identity advertisement. It allows each networking device, such as a Moxa managed
switch/router, to periodically inform its neighbors about itself and its configuration. In this way, all devices will
be aware of each other.
The router’s web interface can be used to enable or disable LLDP, and to set the LLDP Message Transmit
Interval. Users can view each switch’s neighbor-list, which is reported by its network neighbors.
LLDP Setting

5 to 32768 sec. Set the transmit interval of LLDP messages. Unit is in seconds. 30 (sec.)
LLDT Table
Port: The port number that connects to the neighbor device.
Neighbor ID: A unique entity that identifies a neighbor device; this is typically the MAC address.
Neighbor Port: The port number of the neighbor device.
