批量接口配置port-group 技术
port-group group-member g0/0/1 to g0/0/9
port link-type access
port default vlan 2
可实现同时给1-9口配置相同命令
port-group group-member g0/0/10 to g0/0/19
port link-type access
port default vlan 3
上行接口配置
interface GigabitEthernet0/0/23
port link-type trunk
undo port trunk allow-pass vlan 1
port trunk allow-pass vlan 2 to 3
interface GigabitEthernet0/0/24
port link-type trunk
undo port trunk allow-pass vlan 1
port trunk allow-pass vlan 2 to 3
对于未规划用途并且长期不使用的接口进行关闭处理
port-group group-member g0/0/20 to g0/0/22
shutdown
添加接口描述
interface GigabitEthernet0/0/23
description to_BG-AGG-Mster-S5728C_G0/0/23
port link-type trunk
undo port trunk allow-pass vlan 1
port trunk allow-pass vlan 2 to 3
设备命名
[AGG-master]sysname BG-AGG-Mster-S5728C
生成树配置–主设备
stp enable
stp mode mstp
stp region-configuration
region-name BG
revision-level 1
instance 1 vlan 2 to 3
active region-configuration
stp instance 1 root primary
生成树配置–备设备
stp enable
stp mode mstp
stp region-configuration
region-name BG
revision-level 1
instance 1 vlan 2 to 3
active region-configuration
stp instance 1 root primary
生成树配置–非根设备
stp enable
stp mode mstp
stp region-configuration
region-name BG
revision-level 1
instance 1 vlan 2 to 3
active region-configuration
BPDU保护

t GigabitEthernet0/0/2 that enabled BPDU-Protection will be shutdown, because it
received BPDU packet! //开启保护后检测出BPDU关闭改接口。
