| Attribute | Description | ||||||
|---|---|---|---|---|---|---|---|
| Common Writable Attributes | Active, Name | ||||||
| BridgeMacAddr |
MAC address of the bridge - second component of the bridge ID. The MAC address does not have to be unique if it is configured for shared media (not point-to-point). Type: mac Default: 00:00:10:00:10:00 |
||||||
| BridgePriority |
Priority for the bridge. A low numerical value indicates a high bridge priority. The algorithm uses this value during the root bridge election process. The bridge with the highest bridge priority value is elected as the root bridge on the network. Type: u16 Default: 32768 Range: 0 - 65535 |
||||||
| EventLogLevel |
Event log level. Type: enum Default: EVENT_LOG_LEVEL_DEBUG Possible Values:
|
||||||
| ForwardDelay |
Forward delay timer. Specifies the length of time that the bridge remains in the listening and learning states before entering the forwarding state. Type: u8 Default: 15 Range: 4 - 30 |
||||||
| HelloTime |
Time interval between the generation of configuration BPDUs by the root bridge. STP/PVST+ bridge - specifies how often the bridge broadcasts hello messages to other bridges. In 802.1D, hello messages are used as a keep-alive mechanism. RSTP/RPVST+ bridge - specifies how often the bridge sends a BPDU with current information. In 802.1W, BPDUs are used as a keep-alive mechanism. Type: u8 Default: 2 Range: 1 - 10 |
||||||
| HoldCount |
Transmit hold count. The maximum number of BPDUs transmitted per second. Used to limit the transmission rate. Type: u8 Default: 3 Range: 1 - 30 |
||||||
| MaxAgeTime |
Timeout value used to discard messages. Specifies the length of time that the protocol information received on a port is stored by the bridge. This timeout value is used by all bridges in the bridged LAN. The max age value is set by the root. This parameter is conveyed to ensure that each bridge in a bridged LAN has a consistent value against which to test the age of stored configuration information. Type: u8 Default: 20 Range: 6 - 40 |
||||||
| MsgAgeTime |
Age of the message in seconds. Used when STP bridge port is custom. Specifies the configuration age, which is the time since the generation of the configuration BPDU by the root bridge. Type: u8 Default: 1 Range: 1 - 39 |
||||||
| PortNum |
Port number - second component of the port ID. Indicates the port number on the emulated bridge. This number is included in BPFDUs. Type: u16 Default: 1 Range: 1 - 255 |
||||||
| PortPriority |
Priority for the port on the bridge - first component of the port ID. Specifies the priority for the port. A low numerical value indicates a high port priority. The algorithm uses this value to elect the root port. The port with the highest port priority value is elected root port. Type: u16 Default: 128 Range: 0 - 255 |
||||||
| RootBridge |
Initial root bridge on the bridge port. Type: enum Default: 0 Possible Values:
|
||||||
| RootMacAddr |
MAC address of the root bridge - second component of the root bridge ID. Disabled for all MSTP instances other than 0 (CIST). Type: mac Default: 00:00:10:00:10:00 |
||||||
| RootPortCost |
Cost to reach the root bridge. Disabled for all MSTP instances other than 0 (CIST). This value is used by the DUT to determine which port is the primary path to the root bridge. Type: u32 Default: 0 Range: 0 - 200000000 |
||||||
| RootPriority |
Bridge priority for the root bridge - priority component of the root bridge ID. Used to determine which bridge is elected as root. Disabled for all MSTP instances other than 0 (CIST). Type: u16 Default: 32768 Range: 0 - 65535 |
||||||
| UsePartialBlockState |
Whether to use partial block state. Type: bool Default: FALSE Possible Values:
|
| Read-Only Attribute | Description |
|---|---|
| ElectedRoot |
Elected root bridge. Type: string Default: NA |
