To add an Interface Group, click the Add button. The following screen will appear. It lists the available and grouped interfaces.

Follow the instructions shown below:

Figure 81: Advanced - Add Interface Grouping

Automatically Add Clients with the following DHCP Vendor IDs

Add support to automatically map LAN interfaces to PVC’s

using DHCP vendor ID (option 60). The local DHCP server will decline

and send the requests to a remote DHCP server by mapping the appropriate LAN interface. This will be turned on when Interface

Grouping is enabled.

Press the Apply/Save button to save any changes to the configuration settings.

IGMP Configuration

The Internet Group Management Protocol (IGMP) is a communications protocol used by hosts and adjacent routers on IP networks

to establish multicast group memberships. IGMP is a protocol only used on the network between a host and the router. It allows a

host to inform the router whenever that host needs to join or leave a particular multicast group. IGMP provides for more efficient

allocation of resources when used with online gaming and video streaming.

FIELD

DEFINITION

Default Version

The version IGMP in use by the router.

Query Interval

The hosts on the segment report their group membership in response to the

router’s

queries. The query interval

timer is also used to define the amount of time a router will store particular IGMP state if it does not hear any

reports on the group. The query interval is the time in seconds between queries sent from the router to IGMP

hosts.

Query Response Interval

When a host receives the query packet, it starts counting to a random value, less the maximum response time.

When this timer expires, the host replies with a report, provided that no other host has responded yet. This

accomplishes two purposes:

a) Allows controlling the amount of IGMP reports sent during a time window.

b) Engages the report suppression feature, which permits a host to suppress its own report and conserve

bandwidth.

Last Member Query Interval

IGMP uses this value when router hears IGMP Leave report. This means that at least one host wants to leave

the group. After router receives the Leave report, it checks that the interface is not configured for IGMP

Immediate Leave (single-host on the segment) and if not, it sends out an out-of-sequence query.

Robustness Value

The robustness variable is a way of indicating how susceptible the subnet is to lost packets. IGMP can recover

from robustness variable minus 1 lost IGMP packets. You can also click the scroll arrows to select a new

setting. The robustness variable should be set to a value of 2 or greater. The default robustness variable value

is 2

.

Maximum Multicast Groups

The maximum number of multicast groups that the router can control at any one time.

Maximum Multicast Data

Sources

The maximum number of data sources a multicast group can have.

Maximum Multicast Group

Members

The maximum number of hosts a multicast group can have.

Fast Leave Enable

With IGMP fast-leave processing, which means that the router immediately removes the interface attached to a

receiver upon receiving a Leave Group message from a IGMP host.

LAN to LAN (Intra LAN)

multicast

Multicasting across a LAN is enabled.

SIP ALG

The SIP Application Layer Gateway (ALG) provides functionality to allow VoIP traffic to pass both from the private to public and

public to private side of the firewall when using Network Address and Port Translation (NAPT). SIP ALG inspects and modifies SIP

traffic to allow SIP traffic to pass through the firewall.

Diagnostics

The Diagnostics menu provides feedback on the connection status of the device. The individual tests are listed below. If a test

displays a fail status:

1.

Click on the Help link and follow the troubleshooting procedures in the Help screen that appears.

2.

Now click Re-run Diagnostic Tests at the bottom of the screen to re-test and confirm the error

3.

If the test continues to fail, contact Technical Support.

Diagnostics

FIELD

DESCRIPTION

ENET Connection

Pass: Indicates the Ethernet connection to your computer is connected to the LAN port of the router.

Fail: Indicates that the router does not detect the Ethernet interface of your computer.

Test your Wireless Connection

Pass: Indicates that the wireless card is switched ON.

Fail: Indicates that the wireless card is switched OFF.

Test the Assigned IP Address

Pass: Indicates that the modem has received a valid IP address from the PPP server.

Fail: Indicates that the modem has not received a valid IP address from the PPP server.

Ping Primary Domain Name Server

Pass: Indicates that the router can communicate with the DNS server.

Fail: Indicates that the router was unable to communicate with the primary Domain Name Server (DNS).

This may not have an effect on your internet connection. Therefore if this test fails but you are still able

to connect to the internet there is no need to troubleshoot this issue.

System Log

This function allows you to view system events and configure related options. Follow the steps below to enable and view the

System Log.

1.

Click Configure System Log to continue.

Figure 86: Status - System Log

2.

Select the system log options (see table below) and click the Apply/Save button.

Figure 87: Status - Configure System Log

FIELD

DESCRIPTION

Log

Indicates whether the system is currently recording events. System logging can be disabled or enabled.

By default system logging is disabled.

Log Level

Allows you to configure the event level and filter out unwanted events below this level. The events range

from the highest level “Emergency” down to the lowest “Debugging” level

and are stored in the router’s

SDRAM memory. When the log buffer is full the newest event will wrap up to the top of the log buffer

and overwrite the lowest event. By default the log level is “Debugging” which is the lowest critical level.

The log levels are defined as follows:

Emergency is the most serious event level whereas debugging is the least important. For instance if the

log level is set to debugging, all the events from the lowest debugging to the highest Emergency level

will be recorded. If the log level is set to Error level only error level logs will be able to be viewed.

Display

Allows you to select the log events and displays in the View System Log window. For events from

debugging level and above to the highest Emergency level

.

Level

Allows you to select the logged events and display in the View system Log window, per log level.

Mode

Allows you to specify whether events should be stored in local memory, be sent to a remote system log

server or both simultaneously.

If remote mode is selected the view system log windows will not be able to display events saved to the

remote system log server.

When either Remote mode or both mode are selected you will be prompted

for the system log server IP address and UDP port.
