| Enable Rapid | Select this to shorten the DHCPv6 message exchange process from four to two steps. |
| Commit | This function helps reduce heavy network traffic load. |
|
| Note: Make sure you also enable this option in the DHCPv6 clients to make rapid commit |
|
| work. |

|
| Parameters |
|
|
|
|
| Egress | Enter the maximum amount of traffic, in kilobits per second, the ZyWALL can send |
| Bandwidth | 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 ZyWALL 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 ZyWALL divides it |
|
| into smaller fragments. Allowed values are 576 - 1492. Usually, this value is 1492. |
|
|
|
| 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 ZyWALL stops routing to the gateway. The ZyWALL |
|
| 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 ZyWALL regularly ping the gateway you specify to make sure it |
|
| is still available. |
|
| Select tcp to have the ZyWALL 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 ZyWALL stops routing through the |
| Tolerance | gateway. |
|
|
|
| Check Default | Select this to use the default gateway for the connectivity check. |
