常用交换机命令¶
背景¶
最近接触了 Cisco，DELL，Huawei，H3C，Ruijie 的网络设备，发现配置方式各有不同，故记录一下各个厂家的命令。
Huawei¶
测试型号：S5320
保存配置¶
<HUAWEI>save
The current configuration will be written to flash:/vrpcfg.zip.
Are you sure to continue?[Y/N]y
Now saving the current configuration to the slot 0....
Save the configuration successfully.
进入配置模式¶
查看当前配置¶
查看 LLDP 邻居¶
查看 CDP 邻居¶
启用 LLDP¶
启用 CDP¶
启用只读 SNMPv1 community¶
[HUAWEI]snmp-agent sys-info version all
Warning: This command may cause confliction in netconf status. Continue? [Y/N]:y
Warning: SNMPv1/SNMPv2c is not secure, and it is recommended to use SNMPv3.
[HUAWEI]snmp-agent community read [COMMUNITY NAME]
Warning: This command may cause confliction in netconf status. Continue? [Y/N]:y
启用 SNMP iso view¶
默认情况下 SNMP 会缺少一些标准的 MIB（比如 LLDP），可以打开 iso view：
[HUAWEI]snmp-agent mib-view included iso-view iso
Warning: This command may cause confliction in netconf status. Continue? [Y/N]:y
[HUAWEI]snmp-agent community read [COMMUNITY NAME] mib-view iso-view
查看 ARP 表¶
ARPING¶
启用 STP 协议¶
设置 NTP 服务器¶
设置远程 syslog 服务器¶
设置 LACP 链路聚合¶
[HUAWEI-XGigabitEthernet0/0/1]eth-trunk 1
[HUAWEI-XGigabitEthernet0/0/2]eth-trunk 1
[HUAWEI]interface Eth-Trunk 1
[HUAWEI-Eth-Trunk1]mode lacp
DELL¶
测试型号：N3048
保存配置¶
console#copy running-config startup-config
This operation may take few minutes.
Management interfaces will not be available during this time.
Are you sure you want to save? (y/n) y
Configuration Saved!
