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
Bandwidth
Enter the maximum amount of traffic, in kilobits per second, the SBG can send through the
interface to the network. Allowed values are 0 - 1048576.
Ingress
Bandwidth
This is reserved for future use.
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
Check
The interface can regularly check the connection to the gateway you specified to make sure it
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
Connectivity
Check
Select this to turn on the connection 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
Tolerance
Enter the number of consecutive failures before the SBG stops routing through the gateway.
