Configuring session management
Support for session management depends on the device model. For more information about whether the
wireless controller supports session management function, see " About the H3C Access Controllers
Web-Based Configuration Guide ."
This function is used to verify packets through transport layer protocols. The session management feature
tracks the status of connections by inspecting the transport layer protocol (TCP or UDP) information, and
performs unified status maintenance and management for all connections.
Basic session management settings include:
• Configuring whether to enable unidirectional traffic detection.
• Configuring a persistent session rule which is available only for TCP sessions in ESTABLISHED state.
• Setting aging times for the sessions in different protocol states, which are effective only for the
sessions that are being established.
• Setting aging times for the sessions of different application layer protocols, which are effective only
for the sessions in READY or ESTABLISHED state.
NOTE:
If too many sessions, for example, more than 800 thousands sessions, exist, do not set small values for the
aging times of the sessions in different protocol states and of different application layer protocols.
Otherwise, the responses of the console will be very slow.
To configure the basic session management settings:
1. Select Security > Session table from the navigation tree, and click the Configuration tab.
