Usage Guidelines

Application Scenarios

The keepalive function of network extension enables the client to send keepalive packets to the FW to update the SSL session timeout period and HTTPS session aging time. The network-extension keep-alive interval interval configuration on the FW determines the interval at which the client sends keepalive packets. When the network condition is poor (for example, high network delay or packet loss rate), you can run the network-extension keep-alive interval command to set a smaller interval to prevent the FW from incorrectly logging users out.

Prerequisites

The network-extension keep-alive enable command has been used to enable the keepalive function of network extension.

Precautions

The interval at which the client sends keepalive packets should be smaller than the SSL session timeout period or HTTPS session aging time. Otherwise, keepalive will fail.

Do not set a too small interval. Otherwise, too many keepalive packets consume bandwidth resources.

Example

# Set the interval for sending network extension keepalive packets to 60 on virtual gateway gateway.

[sysname] v-gateway gateway
[sysname-gateway] service
