Abstract
According to an example, a Controlling Bridge (CB) receives a VCF registration request packet sent by a Port Extender (PE) and sets interface state of a VCF interface receiving the VCF registration request packet from initial state to blocked state. The CB returns a VCF registration response packet to the PE and receives a VCF registration acknowledge packet returned by the PE after the PE receives the VCF registration response packet. The CB sets interface state of a VCF interface sending the VCF registration request packet from blocked state to forwarding state; sets interface state of the VCF interface receiving the VCF registration request packet as forwarding state, and establishing successfully a VCF link with the PE.
