Parameters

ipv4: Logs IPv4 sessions.

ipv6: Logs IPv6 sessions.

acl acl-number: Specifies an ACL by its number in the range of 2000 to 3999. If you do not specify an ACL, this command enables session logging for all IPv4 or IPv6 sessions on the interface.

inbound: Specifies the inbound direction.

outbound: Specifies the outbound direction.

Usage guidelines

If you do not specify the inbound or the outbound keyword, this command enables session logging on both directions.

A maximum of one IPv4 ACL and one IPv6 ACL can be applied to each direction.

After session logging is enabled, the device outputs session logs as follows:

· Outputs a session log when the specified traffic threshold or interval is reached.

· Outputs a session log when a session entry is created or removed only if the logging for session creation or deletion is enabled.

The session logging feature must work with the flow log or fast log output feature to generate session logs. Session logs can be output in flow log or fast log output format. By default, they are output in flow log format. For information about flow log and fast log output, see Network Management and Monitoring.

Parameters

ipv6: Specifies an IPv6 ACL. To specify an IPv4 ACL, do not specify this keyword.

acl-number: Specifies an ACL by its number in the range of 2000 to 3999.

aging-time time-value: Specifies the aging time for persistent sessions in hours. The value range for the time-value argument is 0 to 360, and the default value is 24. To disable the aging for persistent sessions, set the value to 0.

Usage guidelines

This command is effective only on TCP sessions in ESTABLISHED state.

For a TCP session in ESTABLISHED state, the priority of the aging time is as follows:

· Aging time for persistent sessions.

· Aging time for sessions of application layer protocols.

· Aging time for sessions in different protocol states.

A persistent session is not removed until one of the following events occurs:

· The session entry ages out.

· The device receives a connection close request from the initiator or responder.

· You manually clear the session entries.

The configuration of persistent sessions applies only to new sessions. It has no effect on existing sessions.

Repeat this command to use multiple ACLs to specify persistent sessions.

Examples

# Specify IPv4 ACL 2000 for identifying persistent sessions and set the aging time to 72 hours.

<Sysname> system-view

[Sysname] session persistent acl 2000 aging-time 72

Parameters

compact: Specifies compact mode.

loose: Specifies loose mode.

Usage guidelines

When asymmetric-path traffic exists in a hot backup system operating in session active/standby mode, set the mode of session state machine to loose to avoid abnormal traffic loss.

When asymmetric-path traffic exists in a hot backup system operating in session dual-active mode, set the mode of session state machine to compact for disconnected sessions to age out timely.

As a best practice, change the mode of session state machine only when asymmetric-path traffic exists. This feature degrades performance of session-based security check. Make sure you are fully aware of the impact of this command when you use it on a live network.

If you execute this command multiple times, the most recent configuration takes effect.

Parameters

dns: Specifies the DNS protocol.

http: Specifies the HTTP protocol.

Usage guidelines

DNS or HTTP connections usually do not last long. When a DNS or HTTP connection is terminated because of an active/standby switchover, the client will immediately reinitiate a connection request. The connection exception is barely noticed.

DNS and HTTP sessions do not require session synchronization except for the following conditions:

· Users are aware that the current HTTP or DNS sessions will last for a long time.

· HTTP or DNS session backup is required.

For this command to take effect, you must also configure the session synchronization enable command.

This command takes effect only on sessions of the application protocols HTTP and DNS. Sessions of other application protocols will be backed up if the session synchronization enable command is configured.

Examples

# Enable session synchronization for stateful failover, and enable session synchronization for HTTP.

<Sysname> system-view

[Sysname] session synchronization enable

[Sysname] session synchronization http

Related commands

session synchronization enable

Use session synchronization enable to enable session synchronization for stateful failover.

Use undo session synchronization enable to disable session synchronization for stateful failover.

Syntax

session synchronization enable [ asymmetric ]

undo session synchronization enable

Default

Session synchronization for stateful failover is disabled.

Parameters

asymmetric: Specifies asymmetric traffic. If you do not specify this keyword, this command supports only symmetric traffic.

Usage guidelines

This features enables the master and backup devices to synchronize sessions and dynamic entries of session-based services.

In a network that has asymmetric traffic, heavy service traffic might cause service delay or service unavailable because sessions cannot be backed up timely. For example, one device forwards the TCP SYN packets, and another device forwards its ACK packets. If the session tables of the two devices are not synchronized, the TCP packets will be dropped because of state error. To resolve this issue, use the session synchronization enable asymmetric command.

This command cannot be used together with the hot-backup enable command.For information about the hot-backup enable command, see HA group commands in High Availability Command Reference.

Examples

# Enable session synchronization for stateful failover.

<Sysname> system-view

<Sysname> session synchronization enable

# Enable session synchronization for both symmetric and asymmetric traffic.

<Sysname> system-view

<Sysname> session synchronization enable asymmetric
