[Huawei]info-center logbuffer size ?
INTEGER<0-1024> The size of logging buffer, the default is 5129、配置Log、Trap、Debug信息输出到日志文件
配置Log信息输出到日志文件后，信息可以以文件的形式保存在设备上，便于用户随时查看设备的运行情况。
1、配置日志文件的大小。
如果设备生成的日志文件超过所配置的大小，系统会自动将日志文件按照标准zip格式压缩成压缩文件。
[Huawei]info-center logfile ?
channel Set the channel through which the data is transmitted to the logfile
path Set the save path of logfile
size Set the size of logfile
[Huawei]info-center logfile size ?
INTEGER<4,8,16,32> Specify logfile size, default is 8M2、配置日志文件的最大保存个数。
如果产生的日志文件超过最大个数，系统将删除日期较老的日志文件，保持日志文件个数小于等于所配置的值。
[Huawei]info-center max-logfile-number ?
INTEGER<2-500> File numbers, the default is 2003、手动将日志文件缓冲区中的信息保存到日志文件。
日志文件缓冲区中的信息会定时自动保存到日志文件中或当日志文件缓冲区满时保存到日志文件中。如需要查看当前信息，可以通过该命令把日志文件缓冲区中的信息保存到日志文件后进行查看。
<Huawei>save logfile10、配置Log信息输出到控制台/终端
通过配置Log信息输出到控制台，用户可以在控制台（通过Console口登录到设备上的主机）上查看到Log信息，以便及时监控设备的运行情况。
1、使能终端显示信息中心发送信息的功能
<Huawei>terminal monitor
Info: Current terminal monitor is on.2、使能终端显示Log信息功能
<Huawei>terminal logging
Info: Current terminal logging is on.11、配置Log、Trap、Debug信息输出到日志主机
通过配置Log信息输出到日志主机，用户可以在日志主机上查看到Log信息，以便及时监控设备的运行情况。
1、配置向IPv4/IPv6日志主机输出Log信息
[Huawei]info-center loghost ?
IP_ADDR<X.X.X.X> Logging host ip address
ipv6 Logging host ipv6 address
source Set the source address of packets sent to loghost
[Huawei]info-center loghost 10.1.1.1 ?
binary Send binary log
channel Assign channel to the logging host
facility Set logging host facility
language Set the language environment of logging host
public-net Connect in Public Network
vpn-instance Specify the VPN-Instance name of loghost
<cr> Please press ENTER to execute command
[Huawei]info-center loghost 10.1.1.1 language ?
English Language environment is English
[Huawei]info-center loghost 10.1.1.1 language English ?
channel Assign channel to the logging host
facility Set logging host facility
public-net Connect in Public Network
vpn-instance Specify the VPN-Instance name of loghost
<cr> Please press ENTER to execute command
[Huawei]info-center loghost 10.1.1.1 language English facility ?
local0 Logging host facility
local1 Logging host facility
local2 Logging host facility
local3 Logging host facility
local4 Logging host facility
local5 Logging host facility
local6 Logging host facility
local7 Logging host facility
[Huawei]info-center loghost 10.1.1.1 language English facility local2 ?
channel Assign channel to the logging host
public-net Connect in Public Network
vpn-instance Specify the VPN-Instance name of loghost
<cr> Please press ENTER to execute command2、配置设备向日志主机发送消息的源接口信息
[Huawei]info-center loghost source ?
GigabitEthernet GigabitEthernet interface
NULL NULL interface
[Huawei]info-center loghost source GigabitEthernet 0/0/212、配置Trap信息输出到Trap缓冲区
[Huawei]info-center trapbuffer13、配置Trap信息输出到控制台/终端
<Huawei>terminal trapping
Info: Current terminal trapping is on.14、配置Trap信息输出到SNMP代理
当设备出现异常或故障时，网络管理员希望能及时了解到设备的运行情况，以保证设备的正常工作。通过配置Trap信息输出到网管服务器，可以实现网络管理员对设备的实时监控，及时定位设备运行故障。
配置Trap信息输出到网管之前，需要先配置Trap信息输出到SNMP代理，然后通过SNMP代理向网管服务器发送Trap信息。
1、配置Trap信息输出到SNMP代理所使用的通道
[Huawei]info-center snmp channel ?
INTEGER<0-9> Channel number <0-9>
channel6 6 channel's name is channel6
channel7 7 channel's name is channel7
channel8 8 channel's name is channel8
channel9 9 channel's name is channel9
console 0 channel's name is console
logbuffer 4 channel's name is logbuffer
loghost 2 channel's name is loghost
monitor 1 channel's name is monitor
snmpagent 5 channel's name is snmpagent
trapbuffer 3 channel's name is trapbuffer2、启动SNMP代理功能
[Huawei]snmp-agent15、配置Debug信息输出到控制台/终端
<Huawei>terminal debugging
Info: Current terminal debugging is on.16、清除信息中心的统计信息
<HUAWEI> reset info-center statistics17、清除日志缓存区的统计信息
<Huawei>reset logbuffer
Warning: This command will reset the log buffer. Logs in the buffer will be lost
. Continue? (y18、清除告警缓冲区的统计信息
