Chapter 13 Interfaces Table 62 Configuration > Network > Interface > PPP > Add (continued) LABEL DESCRIPTION Interface Parameters Egress Bandwidth Enter the maximum amount of traffic, in kilobits per second, the ZyWALL 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 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 Connectivity Check Select this to turn on the connection 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 Tolerance Enter the number of consecutive failures before the ZyWALL stops routing through the gateway. Check Default Select this to use the default gateway for the connectivity check. Gateway 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.
