The info-center loghost command configures a device to output logs to a syslog server.
The undo info-center loghost command disables a device from outputting logs to a syslog server.
A device does not output logs to any syslog server by default.

| Parameter | Description | Value |
|---|---|---|
| ipv4-address |
Specifies the IPv4 address of a syslog server. |
The value is in dotted decimal format. |
| local-time |
Indicates the local time. |
- |
| utc |
Indicates the Universal Time Coordinated (UTC). |
- |
| channel channel-number |
Specifies a channel number. |
The value is an integer ranging from 0 to 9.0: console1: monitor2: loghost3: trapbuffer4: logbuffer5: snmpagent6: channel67: channel78: channel89: channel9 |
| channel channel-name |
Specifies a channel name. |
The value is a string:console: Consolemonitor: Remote terminalloghost: Syslog servertrapbuffer: Trap bufferlogbuffer: Log buffersnmpagent: SNMP agentchannel6: Unspecifiedchannel7: Unspecifiedchannel8: Unspecifiedchannel9: Information file |
| public-net |
Indicates the logs sent to a syslog server over the public network. |
- |
| vpn-instance vpn-instance-name |
Specifies name of a virtual private network (VPN) instance of a syslog server. |
The value is a string of 1 to 31 case-sensitive characters, spaces not supported. In addition, the VPN instance name must not be _public_. When double quotation marks are used around the string, spaces are allowed in the string. |
| source-ip source-ip-address |
Specifies the source IPv4 address of packets to be sent to a syslog server. |
The value is in dotted decimal format. |
| source-ip source-ipv6-address |
Specifies the source IPv6 address of packets to be sent to a syslog server. |
The format is H-H-H. Each H represents four hexadecimal digits. |
| facility local-num |
Specifies a syslog server facility that is used to identify the log information source. You can use this parameter to plan a local value for the log information of a specified device, so that the syslog server can handle received log information based on the parameter. |
The value is an enumerated type: local0, local1, local2, local3, local4, local5, local6, or local7. The default value is local7. |
| level level-num |
Specifies a log level. |
The value is an enumerated type: emergencies: an emergency error. alert: an error that needs to be corrected immediately critical: a major error error: a minor error warning: a potential error notification: information that needs to be noticed informational: an informational message debugging: detailed information for debugging use The default value is debugging. |
| port server-port |
Specifies the destination port number of packets to be sent to a syslog server. |
The value is an integer ranging from 1 to 65535.
|
| transport |
Indicates the information transport mode. |
- |
| udp |
Indicates that the information transport mode is UDP. |
- |
| tcp |
Indicates that the information transport mode is TCP. |
- |
| ssl-policy policy-name |
Specifies the name of a Secure Sockets Layer (SSL) policy when packets are transmitted using TCP. SSL encrypted transmission provides high security. If packets are transmitted on insecure networks, configure SSL encrypted transmission by specifying ssl-policy policy-name. If packets are transmitted on secure networks, configure UDP transmission mode by specifying udp or TCP transmission mode by specifying tcp. |
The value is a string of 1 to 23 case-insensitive characters, spaces not supported. |
| security |
Specifies a security log host. If the security parameter is set, the system sends only security logs to the log host. |
- |
| verify-dns-name dns-name |
Specifies the DNS server certificate name for the logging host. |
String form, does not support space, case sensitive, length range is 1 to 255 |
| ipv6 ipv6-address |
Specifies the IPv6 address of a syslog server. |
The value is a hexadecimal number in the format of X:X::X:X. |
Usage Scenario
To configure a device to output logs to a syslog server, run the info-center loghost command. The system logs information about device operations in real time. These logs can be output to the syslog servers for storage and query. If a problem occurs, you can check the logs to learn about what happened to the device during device operation and analyze fault causes.
Prerequisites
Information management has been enabled using info-center enable, and the IP address of a syslog server is reachable.
Configuration Impact
Logs record information about users' operations on an existing device (such as command configuration operation) and specific events (such as a network connection failure). After the info-center loghost command is run, an existing device outputs generated logs to the specified syslog server.
Precautions
The configured log host level does not take effect on security logs.
