H3C irf配置注意事项

1、H3C irf主交换机配置
irf domain 100
irf member 1 priority 30
interface FortyGigE1/0/53
  description "IRF"
  shutdown
interface FortyGigE1/0/54
  description "IRF"
  shutdown
irf-port 1/1
  port group interface FortyGigE1/0/53
  port group interface FortyGigE1/0/54
interface FortyGigE1/0/53
  description "IRF"
  undo shutdown
interface FortyGigE1/0/54
  description "IRF"
  undo shutdown
save  #注意一定先保存配置再active
irf-port-configuration active

2、备机irf配置
irf member 1 renumber 2
reboot    #修改完member号后需要重启交换机
irf domain 100
irf member 2 priority 15
interface FortyGigE2/0/53
  description "IRF"
  shutdown
interface FortyGigE2/0/54
  description "IRF"
  shutdown
irf-port 2/2
  port group interface FortyGigE2/0/53
  port group interface FortyGigE2/0/54
interface FortyGigE2/0/53
  description "IRF"
  undo shutdown
interface FortyGigE2/0/54
  description "IRF"
  undo shutdown
save   #注意一定先保存配置再active
irf-port-configuration active  #备机active会后自动重启，如没有自动重启请检查max-ecmp-num配置两边是否一致

3、修改max-ecmp-num参数后一定要保存配置后再重启，重启之后使用dis max-ecmp-num命令查看是否修改成功
max-ecmp-num 32
dis max-ecmp-num
  Max-ECMP-Num in use:8
  Max-ECMP-Num at the next reboot:32
save
reboot

4、如出现如下报错请检查max-ecmp-num参数是否一致
%Dec 18 15:55:15:935 1976 H3C DRVPLAT/4/DrvDebug:
The port Forty1/0/54 can't receive irf pkt, please check.

5、交换机IOS升级
<H3C>ftp 192.168.1.10
ftp>get S6800-CMW710.ipe
<H3C>boot-loader file flash:/XXXXXXX.ipe all main
<H3C>display boot-loader
<H3C>reboot

6、给IOS打补丁
<H3C>install activate patch flash:/XXXXXX all
<H3C>install commit
display install active

7、清除风扇报错命令
fan perfer-direction slot 1 port-to-power

 8、irf查看命令
dis irf；dis irf top；dis irf link

9、H3C光纤接口诊断
[H3C-Ten-GigabitEthernet1/0/1] loopback internal   #开启以太网口内部环回功能用来测试接口(使用此命令不要接上光纤跳线)
[H3C-Ten-GigabitEthernet1/0/1] port up-mode        #强制up接口
[H3C]dis transceiver dia interface te 1/0/1              #查看光口光收发是否正常
Ten-GigabitEthernet1/0/1 transceiver diagnostic information:
    Current diagnostic parameters(当前诊断值):
         Temp.( Voltage(V)     Bias(mA)     RX power(dBm)     TX power(dBm)
           32            3.32             6.42                -2.38                     -2.05
     Alarm thresholds(告警阀值)：
    (下面的值为告警阀值的取值范围，当前诊断值在告警阀值范围内表示光纤收发正常)
                  Temp.( Voltage(V)     Bias(mA)     RX power(dBm)     TX power(dBm)
       High      81             3.80          16.50                1.00                       1.00
       Low       0               2.81          1.00                 -11.90                   -10.30
