Packets sent by PCs are VLAN untagged. If a PC is directly attached to a wiring-closet switch, set the
port on the switch as an access or trunk port:
If the port is set as an access port, assign it to the SVLAN.
If the port is set as a trunk port, specify the SVLAN as the default VLAN.
2) Configuring Switch B
Configure Switch B in the same procedure as on Switch A.
3) Configuring Switch C
# Enable DHCP snooping.
<SwitchC> system-view
[SwitchC] dhcp-snooping
# Create the CVLANs and SVLANs, and enable ARP detection in each VLAN.
