LABEL DESCRIPTION
Automatically Select this to have the SBG detect IPv4 address automatically through DHCP.
configured by
This option is configurable only when you set the method of encapsulation to IPoE.
DHCPC
Manual Select this to manually configure an IPv4 address of the relay server.
Configuration
Service Provider Enter an IPv6 prefix for tunneling IPv6 traffic to the ISP's Border Relay router and connecting to
IPv6 Prefix the native IPv6 Internet.
IPv4 Mask Enter the subnet mask number (1~32) for the IPv4 network.
Length
Border Relay When you select Manual Configuration, specify the relay server IPv4 address.
IPv4 Address
VLAN These fields disappear when the Type is set to ADSL/VDSL over PTM and the method of
encapsulation is PPPoA or IPoA.
Enable Select this option to add the VLAN tag (specified below) to the outgoing traffic through this
connection.
802.1p IEEE 802.1p defines up to 8 separate traffic types by inserting a tag into a MAC-layer frame that
contains bits to define class of service.
Select the IEEE 802.1p priority level (from 0 to 7) to add to traffic through this connection. The
greater the number, the higher the priority level.
VLAN ID Type the VLAN ID number (from 1 to 4094) for traffic through this connection.
Interface Parameters
Egress Enter the maximum amount of traffic, in kilobits per second, the SBG can send through the
Bandwidth interface to the network. Allowed values are 0 - 1048576.
Ingress This is reserved for future use.
Bandwidth
Enter the maximum amount of traffic, in kilobits per second, the SBG can receive from the
network through the interface. Allowed values are 0 - 1048576.
MTU Enter the MTU (Maximum Transfer Unit) size for this traffic.
Type the maximum size of each data packet, in bytes, that can move through this interface. If a
larger packet arrives, the SBG divides it into smaller fragments. Allowed values are 68 -1492.
Usually, this value is 1500.
Connectivity The interface can regularly check the connection to the gateway you specified to make sure it
Check is still available. You specify how often the interface checks the connection, how long to wait for
a response before the attempt is a failure, and how many consecutive failures are required
before the SBG stops routing to the gateway. The SBG resumes routing to the gateway the first
time the gateway passes the connectivity check.
Enable Select this to turn on the connection check.
Connectivity
Check
Check Method Select the method that the gateway allows.
Select ICMP to have the SBG regularly ping the gateway you specify to make sure it is still
available.
Select TCP to have the SBG regularly perform a TCP handshake with the gateway you specify to
make sure it is still available.
Check Period Enter the number of seconds between connection check attempts.
Check Timeout Enter the number of seconds to wait for a response before the attempt is a failure.
Check Fail Enter the number of consecutive failures before the SBG stops routing through the gateway.
