| EnableMacAddrReduction |
Enables or disables MAC address reduction. This is used only with PVSTP and RPVSTP. Some switches support only 1,024 MAC addresses that can be used as bridge identifiers for VLANs running PVSTP. Each bridge must have its own unique identifier in the network. Normally the VLAN ID is added to the MAC address to make up the MAC address, but with MAC address reduction enabled, the VLAN address is added to the bridge priority. MAC address reduction is used to enable extended range VLAN identification. MAC address reduction results in a unique MAC address by deriving the last 3 bytes of the address from the VLAN ID. This ensures that each instance has a unique MAC address for use in the bridge ID. If enabled, the VLAN ID is put in the last 3 bytes of the priority portion of the bridge ID. If disabled, the VLAN ID is put in the last 3 bytes of the MAC address portion of the bridge ID. Type: bool Default: FALSE Possible Values:

| EnablePt2PtLink |
Enables point-to-point connection or shared media. Type: bool Default: FALSE Possible Values:

||||||||||||
| EthernetType |
EtherType field, used with PVSTP and RPVSTP. For a tagged STP BPDU (the Cisco proprietary BPDU for a non-native VLAN), the packet contains the EtherType. Type: string Default: 8100 |
||||||||||||
| NativeVlan |
Supports the Cisco native VLAN. This is the VLAN ID of the native VLAN. BPDUs are sent out for the native VLAN. The first BPDU is the standard IEEE 802.ID BPDU, and the second is the Cisco STP BPDU. The Cisco STP BPDU is sent untagged to the STP MAC address 0100.Occc.cccd on the native VLAN of the trunk. A native VLAN is associated with a particular VLAN ID number. A native VLAN specifies which VLAN BPDUs are sent without a VLAN tag. If the native VLAN ID is 1, two BPDUs are sent untagged. One is a PVST/RPVST BPDU, and the other is an RSTP/STP BPDU. If the native VLAN ID is not 1, only a PVST/RSTP BPDU is transmitted. Type: u16 Default: 1 Range: 1 - 4094 |
