The WX1800H series, WX2500H series, and WX3000H series access controllers do not support the slot keyword or the slot-number argument.
The storage media supported by the device depends on the device model. A CF card is used as an example.

Traditionally, logs generated by different modules must be sent to the device information center before being output to log hosts or other destinations.
The custom log output feature enables fast delivery of logs. Logs that are sent as custom logs are not sent to the information center. Instead, they are sent directly to the log hosts specified by using the customlog host command.
The custom log output feature is available for the AFT, attack defense, NAT, packet filter, and session modules. See related documents for information about these modules.
To output custom NAT logs to a log host, you must specify the log format required by the log host in the customlog format and customlog host commands.
Logs of the AFT, attack defense, packet filter, and session modules can be output as custom logs only in H3C format.
Examples
# Enable custom log output in unicom format for NAT logs.
[Sysname] customlog format nat unicom

Default
No log hosts are specified to receive custom NAT logs.

Parameters
hostname: Specifies a log host by its name, a case-insensitive string of 1 to 253 characters. The host name can contain letters, digits, and special characters including hyphen (-), underscore (_), and dot (.).
ipv4-address: Specifies a log host by its IPv4 address.
ipv6 ipv6-address: Specifies a log host by its IPv6 address.
port port-number: Specifies the port number of the log host. The value range is 1 to 65535, and the default is 514. The setting must be the same as the port number configured on the log host. Otherwise, the log host cannot receive custom logs.
aft: Outputs logs of the AFT module to the log host.
attack-defense: Outputs logs of the attack defense module to the log host.
cmcc-sessionlog: Outputs NAT session logs in cmcc format to the log host.
cmcc-userlog: Outputs NAT user logs in cmcc format to the log host.

You can use the customlog host command to specify a maximum of four log hosts.
The customlog host command takes effect only after the customlog format command is configured.
To output custom NAT logs to a log host, you must specify the log format required by the log host in the customlog format and customlog host commands.
Logs of the AFT, attack defense, packet filter, and session modules can be output as custom logs only in H3C format.
Examples
# Output NAT session logs and user logs in unicom format to the log host 1.1.1.1.
[Sysname] customlog host 1.1.1.1 port 1000 export unicom-sessionlog unicom-userlog

Predefined user roles
network-admin
Usage guidelines
Outputting consecutive duplicate logs at an interval of less than 30 seconds wastes system and network resources.
With this feature enabled, the system starts a suppression period when outputting a new log:
· During the suppression period, the system does not output logs with the same module name, level, mnemonic, location, and text as the previous log.
· After the suppression period expires, if the same log continues to appear, the system outputs the suppressed logs and the log number and starts another suppression period. The suppression period is 30 seconds the first time, 2 minutes the second time, and 10 minutes for subsequent times.
· If a different log is generated during the suppression period, the system aborts the current suppression period, outputs suppressed logs and the log number and then outputs the new log, starting another suppression period.
Examples
Suppose the IP address of VLAN-interface 100 on device A conflicts with that of another device on the network, device A will output the following log information repeatedly:
%Jan 1 07:27:48:636 2000 Sysname ARP/6/DUPIFIP:
Duplicate address 172.16.0.1 on interface Vlan-interface100, sourced from 00e0-fc58-123d
# Enable duplicate log suppression on device A.
<Sysname> system-view
[Sysname] info-center logging suppress duplicates
Device A continues to output the following log information:
%Jan 1 07:27:48:636 2000 Sysname ARP/6/DUPIFIP:

Duplicate address 172.16.0.1 on interface Vlan-interface100, sourced from 00e0-fc58-123d
This message repeated 4 times in last 30 seconds.
The output shows that after the duplicate log suppression feature is enabled, the system outputs another duplicate log and starts the first suppression period for 30 seconds.

Parameters
usage: Specifies an alarm threshold. The value must be an integer in the range of 1 to 100.
Usage guidelines
When the security log file is full, the system deletes the oldest logs and then writes new logs to the security log file. This feature helps avoid security log loss by setting an alarm threshold for the security log file usage. When the threshold is reached, the system outputs log information to inform the administrator. The administrator can log in to the device as the security log administrator, and back up the security log file.

Parameters
module-name: Specifies a module by its name. For instance, to output FTP information, set this argument to FTP. You can use the info-center source ? command to view the modules supported by the device.
default: Specifies all modules, which can be displayed by using the info-center source ? command.
console: Outputs logs to the console.
logbuffer: Outputs logs to the log buffer.
logfile: Outputs logs to the log file.
loghost: Outputs logs to the log host.
monitor: Outputs logs to the monitor terminal.
deny: Disables log output.
level severity: Specifies a severity level in the range of 0 to 7. The smaller the severity value, the higher the severity level. See Table 2 for more information. Logs at the specified severity level and higher levels are allowed or denied to be output.
Usage guidelines
If you do not set an output rule for a module, the module uses the default output rule or the output rule set by using the default keyword.
If you use the command multiple times, only the most recent output rule takes effect for the specified module.
After you set an output rule for a module, you must use the module-name argument to modify or remove the rule. A new output rule configured by using the default keyword does not take effect on the module.
Examples
# Output only VLAN module's information with the emergency level to the console.
<Sysname> system-view
[Sysname] info-center source default console deny
[Sysname] info-center source vlan console level emergency
# Based on the previous configuration, disable output of VLAN module's information to the console so no system information is output to the console.

Parameters
buffersize: Specifies the maximum number of log traps that can be stored in the log trap buffer. The value range is 0 to 65535. Value 0 indicates that the device does not buffer log traps.
Usage guidelines
Log traps are SNMP notifications stored in the log trap buffer. After the snmp-agent trap enable syslog command is configured, the device sends log messages in SNMP notifications to the log trap buffer. You can view the log traps by accessing the MIB corresponding to the trap buffer.
The default buffer size is usually used. You can adjust the buffer size according to your network condition. New traps overwrites the oldest traps when the log trap buffer is full.

# Set the log trap buffer size to 2048.

This command enables the device to send an SNMP notification for each log message it outputs. The device encapsulates logs in SNMP notifications and then sends them to the SNMP module and the log trap buffer.
You can configure the SNMP module to send received SNMP notifications in SNMP traps or informs to remote hosts. For more information, see Network Management and Monitoring Configuration Guide.
To view the traps in the log trap buffer, access the MIB corresponding to the log trap buffer. The log trap buffer size can be set by using the info-center syslog trap buffersize command.

· The terminal logging level 7 command enables log display for all levels (levels 0 through 7) on the current terminal.
· The terminal debugging command only enables display of logs with the following severity levels:
¡ Debug level (level 7).
¡ Severity level higher than or equal to the level specified in the terminal logging level command.
