LABEL DESCRIPTION
Suffix Enter the ending part of the IPv6 network address plus a slash (/) and the prefix length. The
Address
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
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 This is reserved for future use.
Bandwidth
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 Select this to turn on the connection check.
Connectivity
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 Enter the number of consecutive failures before the Zyxel Device stops routing through the
Tolerance
gateway.
Check Default Select this to use the default gateway for the connectivity check.
Gateway
Check this Select this to specify a domain name or IP address for the connectivity check. Enter that
address
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.
DHCP Setting This section appears when Interface Type is internal or general.
