Core switches on dividing a DHCP IP address pool of more than one VLAN, interface to do the trunk link again, does not divide trunk VLAN, allowing all VLAN through,
Access switches connected to the core switch mouth to do the same trunk configuration, only the connected to the client interface for the access link, and the division of VLAN,

CodePudding user response:

Because vlan can separate broadcast domain, the access switch data is passed into the corresponding vlan tag, corresponding to the DHCP request broadcast messages in the corresponding vlan DHCP service processing,
