華為eNSP——DHCP中繼配置

實驗環(huán)境

R4作為DHCP服務(wù)器，R1，R2上做中繼服務(wù)，實現(xiàn)不同網(wǎng)段的pc獲取地址

Info: This operation may take a few seconds. Please wait for a moment...done.
[SW1]int e0/0/1     ##進接口
[SW1-Ethernet0/0/1]port link-type access    ##配置為access口
[SW1-Ethernet0/0/1]port default vlan 10      ##將接口放到vlan10中
[SW1-Ethernet0/0/1]un sh                           ##開啟
