[Huawei]int Eth-Trunk 1

[Huawei-Eth-Trunk1]port link-type trunk   设Eth-Trunk 1 上的端口为 Trunk 端口

[Huawei-Eth-Trunk1]port trunk allow-pass vlan all

[Huawei-Eth-Trunk1]trunkport GigabitEthernet 0/0/2

[Huawei-Eth-Trunk1]trunkport GigabitEthernet 0/0/7

[Huawei-Eth-Trunk1]dis this

#

interface Eth-Trunk1

 port link-type trunk

 port trunk allow-pass vlan 2 to 4094

#

return

[Huawei-Eth-Trunk1]qui

[Huawei]dis eth-trunk 1

Eth-Trunk1's state information is:

WorkingMode: NORMAL         Hash arithmetic: According to SIP-XOR-DIP        

Least Active-linknumber: 1  Max Bandwidth-affected-linknumber: 8             

Operate status: up          Number Of Up Port In Trunk: 2                    

--------------------------------------------------------------------------------

PortName                      Status      Weight

GigabitEthernet0/0/2          Up          1               确保都处于开启状态

GigabitEthernet0/0/7          Up          1

undo info-center enable

是一条 Huawei 设备命令，用于关闭设备的信息中心功能。当 undo info-center enable 命令被执行时，信息中心功能将被关闭，设备将不再记录和输出任何日志信息。这条命令通常被用于调试和测试过程中，或者在不需要进行日志记录的情况下，关闭信息中心以减少设备的负载和消耗。

virtual-ip 192.168.10.252

表示设置 VRRP 虚拟 IP 地址为 192.168.10.252。VRRP 虚拟 IP 地址是一组 VRRP 路由器共享的 IP 地址，用于作为默认网关向外提供服务，客户端设备可以将该 IP 地址配置为其默认网关。

vrrp vrid 10 virtual-ip 192.168.10.252

命令的作用是将当前设备配置为一组 VRRP 路由器中的一员，虚拟路由器 ID 为 10，共享的虚拟 IP 地址为 192.168.10.252，并通过 VRRP 协议与其他 VRRP 路由器实现状态同步和故障转移。

vrrp vrid 10：

指定 VRRP 的虚拟路由器 ID，该 ID 必须在 1 到 255 的范围内。

priority 120：
