Between different VLANs, the same protocol type andencapsulation format can be configured, but cannot be distributed to the same port.Even the user-defined template and standard template with the same encapsulationformat cannot be distributed to the same port.z If protocol has been distributed to a VLAN, the VLAN cannot be removed.z If a protocol of a VLAN has been distributed to a port, the port cannot be removedfrom the VLAN.z If a protocol of a VLAN has been distributed to a port, the protocol cannot beremoved from the VLAN.2.3.3 Associating a Card with the Protocol-Based VLANFollow these steps to create protocol-based VLAN on specific card:
