The following apply to v-VPLS SAP configuration:
• An SAP can only be configured on dot1q Ethernet encapsulation access/hybrid 
ports.
• The v-VPLS operates in the context of a homogeneous VLAN ID, where all 
Ethernet dot1q v-VPLS SAPs must refer to the v-VPLS VLAN ID.
• A v-VPLS SAP can only be simultaneously configured on a single v-VPLS.
• A v-VPLS SAP on a hybrid port cannot be configured with a * encap value.
• A v-VPLS SAP on a hybrid port cannot be configured with NULL encap value, if 
another network interface is already configured with NULL encap value, 
associated with the same hybrid port.
• A v-VPLS SAP on a hybrid port cannot be configured with an encap value of 'X', 
if another network interface is already configured with the same encap value 'X', 
associated with the same hybrid port.
Rules for handling frames in a v-VPLS are described in “v-VPLS traffic processing”.
