华三交换机常用配置

一.堆叠

1.设置第一台交换机成员号及优先级

[H3C]irf member 1 priority 32

2.关闭需要用到的端口

[H3C]interface range Ten-GigabitEthernet 1/0/51 to Ten-GigabitEthernet 1/0/52
[H3C-if-range]shutdown

[H3C-if-range]quit

3.创建IRF虚拟接口

[H3C]irf-port 1/1
[H3C-irf-port1/1]port group interface Ten-GigabitEthernet 1/0/51
You must perform the following tasks for a successful IRF setup:
Save the configuration after completing IRF configuration.
Execute the "irf-port-configuration active" command to activate the IRF ports.
[H3C-irf-port1/1]port group interface Ten-GigabitEthernet 1/0/52
[H3C-irf-port1/1]quit

Please reboot the device for the new member ID to take effect.
[H3C]save force

[H3C]quit
<H3C>reboot
Start to check configuration with next startup configuration file, please wait.........DONE!
This command will reboot the device. Continue? [Y/N]:y
Now rebooting, please wait....%Jul 28 12:29:24:138 2023 H3C DEV/5/SYSTEM_REBOOT: System is rebooting now.
[H3C]interface range Ten-GigabitEthernet 2/0/51 to Ten-GigabitEthernet 2/0/52

6.验证是否成功

[H3C]dis irf
MemberID    Role    Priority  CPU-Mac         Description
 *+1        Master  32        a055-2311-0104  ---
   2        Standby 1         a055-28a6-0204  ---
--------------------------------------------------
 * indicates the device is the master.
 + indicates the device through which the user logs in.

 The bridge MAC of the IRF is: a055-2311-0100
 Auto upgrade                : yes
 Mac persistent              : 6 min
 Domain ID                   : 0

二.snmp配置

1.SNMP v2

[H3C]snmp-agent

[H3C]snmp-agent sys-info version v2c
SNMPv1 and SNMPv2c are insecure because they transmit the community string and data in plaintext form.

[H3C]snmp-agent community read xxx    #xxx为团体名

[H3C]snmp-agent target-host trap address udp-domain xx.xx.xx.xx udp-port 161 params securityname xxx    #xx.xx.xx.xx为NMS地址，xxx为团体名
