System Management Tab - SNMP

SNMP, Simple Network Management Protocol, is a network protocol that provides network administrators with

the ability to monitor the status of the Router and receive notification of any critical events as they occur on the

network. The Router supports SNMP v1/v2c and all relevant Management Information Base II (MIBII) groups. The

Router replies to SNMP Get commands for MIBII via any LAN (local) interface and supports a custom MIB for

generating trap messages.

To enable SNMP, keep the

Enable

box checked. To disable the SNMP agent, remove the checkmark.

To configure SNMP, complete all fields on this screen.

System Name. Enter the hostname of the Router.

System Contact. Enter the name of the network administrator for the Router, as well as a contact number or

e-mail address.

System Location. Enter the location of the Router. For example, you could include the name of the building, floor

number, and room location, such as Head Office - Floor 5 - Networking 3.

Get Community Name. Create a name for the group or community of administrators who can view the Router’s

SNMP data. The default name is

public

.

Set Community Name. Create a name for the group or community of administrators who can receive the Router’s

SNMP traps. The default name is

private

. A name must be entered in this field.

Trap Community Name. Enter the password required by the remote host computer that will receive trap messages

or notices sent by the Router.

Send SNMP Trap to. Enter the IP address of the remote host computer that will receive the trap messages.

System Management Tab - Diagnostic

System Management Tab - Diagnostic

The Router has two built-in tools, DNS Name Lookup and Ping, which are used for troubleshooting network

problems.

The Internet has a service called the Domain Name Service (DNS), which allows users to enter an easily

remembered host name, such as www.linksys.com, instead of numerical TCP/IP addresses to access Internet

resources. The Router’s DNS Name Lookup tool will return the numerical TCP/IP address of a host name.

The ping test bounces a packet off a machine on the Internet back to the sender. This test shows if the Router is

able to contact the remote host. If users on the LAN are having problems accessing services on the Internet, try

pinging the DNS server or other machine at the ISP’s location. If this test is successful, try pinging devices

outside the ISP. This will show if the problem lies with the ISP’s connection.

Select which tool you want to use,

DNS Name Lookup

or

Ping

.

DNS Name Lookup

Before using this tool, make sure the IP address of the DNS server is entered on the Network page of the Setup

tab; otherwise, this tool will not work.

Enter the host name in the

Look up the name

field, and click the

Go

button. (Do not add the prefix

http://

or else

you will get an error message.) The Router will then query the DNS server and display the result at the bottom of

the screen.

Ping

Before using this tool make sure you know the device or host’s IP address. If you do not know it, use the Router’s

DNS Name Lookup tool to find the IP address.

In the

Ping host or IP address

field, enter the IP address of the device being pinged, and click the

Go

button. The

test will take a few seconds to complete. When completed, the Router will display the results at the bottom of the

screen. The results include this information: number of packets transmitted, received, or lost, as well as round

trip time (minimum, maximum, and average).

System Management Tab - Restart

If you need to restart the Router, it is highly recommended that you use the Restart tool on this screen. When you

restart from the

Restart

screen, then the Router will send out your log file before it is reset.

Before restarting the Router, decide which firmware version you want the Router to use. The Active Firmware

Version is the one currently used by the Router. The Backup Firmware Version may be the same as the active one,

or it may be an older version if you have upgraded the Router’s firmware. Select which firmware version you want

the Router to use, the

Active Firmware Version

or

Backup Firmware Version

. Then click the

Restart Router

button to restart the Router.

System Management Tab - Setting Backup

This screen allows you to make a backup file of your preferences file for the Router. To save the backup file, you

need to export the configuration file. To use the preferences file, you need to import the configuration file.

Import Configuration File

To import a configuration file, first specify where your preferences file is located. Click the

Browse

button, and a

dialog box will appear and ask you to select the appropriate configuration file. After you select the file, click the

Import

button. This process may take up to a minute. Then you will need to restart the Router so the changes will

take effect.

Export Configuration File

To export the Router’s current configuration file, click the

Export

button, and a dialog box will appear and ask you

to select a location where you would like to store your preferences file. This file will be called

RV016.exp

by

default, but you may rename it if you wish. This process may take up to a minute.

Port Management Tab - Port Setup

On this screen you can choose the number of WAN ports the Router will provide and configure the connection

settings for each port, such as priority, speed, and duplex. You can also enable or disable the auto-negotiation

feature for all ports.

From the drop-down menu, select how many WAN ports you prefer to use. The default is

2

, while the maximum is

7. You can also change the number of WAN ports using the Network page of the Setup tab. If you change the

number on this screen, then the number on the

Network

screen will change accordingly. Make sure the network

configuration matches the number of WAN port settings on this screen.

If you change the number of WAN ports, a confirmation message will appear. Make sure your network

configuration matches the new WAN settings. Then click the

OK

button to save the new setting.

The Basic Per Port Config. table will display the WAN port numbers in the Port ID column and their respective

settings in the Interface, Disable, Priority, Speed, and Duplex columns. Click

Enable

in the Auto Negotiation

column if you want the Router’s ports to auto-negotiate connection speeds and duplex mode; then you will not

need to set up speed and duplex settings separately.

Basic Per Port Config. Table

Port ID. The port number or name is displayed.

Interface. The port’s interface type is shown here.

Disable. You can select specific ports to disable. Click the checkbox to disable a specific port.

Priority. From the drop-down menu, select

High

or

Normal

for port-based QoS (Quality of Service). QoS is used to

maximize network performance, and this setting allows you to prioritize performance on all ports.

Speed. You can manually configure each port’s speed as 10Mbps or 100Mbps.

Duplex. You can manually configure each port’s duplex mode as half-duplex or full-duplex.

Auto Negotiation. You can set each port to auto-negotiation mode, so you will not need to set up speed and duplex

settings separately.
