10.9 VLAN Interfaces
A Virtual Local Area Network (VLAN) divides a physical network into multiple logical networks. The
standard is defined in IEEE 802.1q.
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. This setting is used in
WAN load balancing and bandwidth management.
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 This section is available if you are configuring a GRE tunnel.
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 displays when you set the Check Method to tcp. Specify the port number to use for
a TCP connectivity check.
