forward protocol udp 67(active)! ip helper-address 192.168.1.8 说明:dhcp来源于bootp(主机引导协议),它是主机在boot时靠udp广播来获取ip地址。使用ip forward-protocol udp bootps(bootpc)是因为dhcp的服务和客户分别用udp的67与68地址来分配和获取IP地址的。其实上述命令等同于ip forward-pro udp 67(68)。

Solved: I have multiple Layer 3 SVI configured on the core switch and all of them are configured with ip helper-address command which by default enables ip forward-protocol . Now we have a requirement to add ip forward-protocol udp PORT# command.
