session log bytes-active

Use session log bytes-active to set the byte-based threshold for traffic-based logging.

Use undo session log bytes-active to restore the default.

Syntax

Default

The device does not output session logs based on the byte-based threshold.

Views

Predefined user roles

network-admin

Parameters

bytes-value: Specifies the byte-based threshold in the range of 1 to 1000 MB.

Usage guidelines

If you set both the traffic-based and time-based logging, the device outputs a session log when whichever is reached. After outputting a session log, the device resets the traffic counter and restarts the interval for the session.

Only one traffic-based threshold can take effect. If you set both the byte-based and packet-based thresholds, the most recent configuration takes effect.

Examples

# Configure the device to output session logs on a per-10-MB basis.

<Sysname> system-view

Syntax

undo session log enable { ipv4 | ipv6 } [ acl acl-number ] { inbound | outbound }

Default

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.

If you do not set the traffic threshold or the interval but you enable session logging, the device outputs a session log when a session entry is created or removed.

Examples

# Enable IPv4 session logging in the inbound direction of VLAN-interface 100.

<Sysname> system-view

[Sysname] interface vlan-interface 100

[Sysname-Vlan-interface 100] session log enable ipv4 inbound

# Enable session logging on VLAN-interface 101 for IPv4 sessions that match ACL 2050 in the outbound direction.

network-admin

Parameters

packets-value: Specifies the packet-based threshold in the range of 1 to 1000 mega-packets.

Usage guidelines

Only one traffic-based threshold can take effect. If you set both the byte-based and packet-based thresholds, the most recent configuration takes effect.

Examples

# Configure the device to output session logs on a per-10-mega-packet basis.

Parameters

time-value: Specifies the interval in minutes. The value range for the time-value argument is 10 to 120 and the value must be integer times of 10.

Usage guidelines

If you set both time-based and traffic-based logging, the device outputs a session log when whichever is reached. After outputting a session log, the device resets the traffic counter and restarts the interval for the session.

Examples

# Configure the device to output session logs every 50 minutes.

Default

No persistent sessions exist.

Views

System view

Predefined user roles

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
