Two catalyst switches connected to each other and all ports of both are in VLAN 2. Ports that connect both switches are access ports (no Trunk) as both switches' ports are in VLAN 2, no any other VLAN. Native VLAN is still VLAN 1. So my question is how will be the control traffic? what VLAN does the control traffic use?
Control traffic = STP,CDP,DTP,VTP,PagP etc.
