Suffix
Address
Enter the ending part of the IPv6 network address plus a slash (/) and the prefix length. The
Zyxel Device will append it to the selected delegated prefix. The combined address is the
network prefix for the network.
For example, you got a delegated prefix of 2003:1234:5678/48. You want to divide it into
2003:1234:5678:1111/64 for this interface and 2003:1234:5678:2222/64 for another interface.
You can use ::1111/64 and ::2222/64 for the suffix address respectively. But if you do not
want to divide the delegated prefix into subnetworks, enter ::0/48 here, which keeps the
same prefix length (/48) as the delegated prefix.
Address
This is the final network prefix combined by the delegated prefix and the suffix.
Note: This field displays the combined address after you click
OK
and reopen this
screen.
Interface Parameters
Egress Bandwidth Enter the maximum amount of traffic, in kilobits per second, the Zyxel Device 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 Zyxel Device can receive
from the network through the interface. Allowed values are 0 - 1048576.
MTU
Maximum Transmission Unit. Type the maximum size of each data packet, in bytes, that can
move through this interface. If a larger packet arrives, the Zyxel Device divides it into smaller
fragments. Allowed values are 576 - 1500. Usually, this value is 1500.
Connectivity Check
These fields appear when
Interface Properties
is
External
or
General
.
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 Zyxel Device stops routing to the gateway. The Zyxel Device
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 Zyxel Device regularly ping the gateway you specify to make sure
it is still available.
Select
tcp
to have the Zyxel Device 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 Zyxel Device stops routing through the
gateway.
Check Default
Gateway
Select this to use the default gateway for the connectivity check.
Check this
address
Select this to specify a domain name or IP address for the connectivity check. Enter that
domain name or IP address in the field next to it.
Check Port
This field only displays when you set the
Check Method
to
tcp
. Specify the port number to
use for a TCP connectivity check.
