slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command displays batch hot-backup state information on all cards.

Usage guidelines

Before you install or remove a card, or modify card configuration, use this command to verify that the batch hot-backup state of the card is Not running. If the batch hot-backup state of the card is Running, do not perform those card operations.

Examples

# Display batch hot-backup state information for all cards.

<Sysname> display session batch-hot-backup state

network-admin

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.

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

# Specify IPv6 ACL 3000 for identifying persistent sessions and set the aging time to 100 hours.

Parameters

dns: Specifies the DNS protocol.

http: Specifies the HTTP protocol.

Usage guidelines

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

Use this command to enable session synchronization for DNS and HTTP in 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.

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.

Usage guidelines

After you enable SNMP notifications for session entry resources, the device generates a notification when hardware session entry resources are exhausted or when the device recovers from the resource exhaustion condition.

For SNMP notifications to be sent correctly, you must also configure SNMP on the device. For more information about SNMP configuration, see Network Management and Monitoring Configuration Guide.
