Description:
Control Protocol Disposition for VTP (VLAN Trunking Protocol). MAC Address (01:00:0C:CC:CC:CC), Ethertype(0x2003).
What is cmEthernetTrafficPortCpdV2VtpDispType?
This object controls the handling of VTP (VLAN Trunking Protocol) control frames on an Ethernet port, with configuration options for MAC address (01:00:0C:CC:CC:CC) and EtherType (0x2003) filtering. Operators set this to allow, block, or selectively forward Cisco's proprietary VLAN management protocol, protecting the network from unauthorized VLAN configuration or reducing management traffic in multi-vendor environments. This is essential for maintaining VLAN security and preventing accidental VLAN topology changes.
