This table describes interface configurations on an ERPS ring.
The indexes of the table are hwConfigRingId, hwConfigPortType, hwConfigPortId1, hwConfigPortId2, hwConfigPortId3, hwConfigPortId4.
| OID | Object | Syntax | Max Access | Description | Implemented Specifications | 
|---|---|---|---|---|---|
| 1.3.6.1.4.1.2011.5.25.256.1.4.1.1 | hwConfigPortType | Unsigned32{(1,1)} | not-accessible | This object indicates the interface type on the ring. Currently, ERPS supports only Ethernet interfaces. The value is fixed at 1. | This object is implemented as defined in the corresponding MIB files. | 
| 1.3.6.1.4.1.2011.5.25.256.1.4.1.2 | hwConfigPortId1 | Unsigned32{(0,2147483647)} | not-accessible | This object indicates the interface identified by Id1 on the ring. When the hwConfigPortType value is 1, this object indicates the interface index on the ring. | This object is implemented as defined in the corresponding MIB files. | 
| 1.3.6.1.4.1.2011.5.25.256.1.4.1.3 | hwConfigPortId2 | Unsigned32{(0,2147483647)} | not-accessible | This object indicates the interface identified by Id2. This field is used for extension and is not used currently. The value should be set to 0. | This object is implemented as defined in the corresponding MIB files. | 
| 1.3.6.1.4.1.2011.5.25.256.1.4.1.4 | hwConfigPortId3 | Unsigned32{(0,2147483647)} | not-accessible | This object indicates the interface identified by Id3. This field is used for extension and is not used currently. The value should be set to 0. | This object is implemented as defined in the corresponding MIB files. | 
| 1.3.6.1.4.1.2011.5.25.256.1.4.1.5 | hwConfigPortId4 | Unsigned32{(0,2147483647)} | not-accessible | This object indicates the interface identified by Id4 on the ring. This field is used for extension and is not used currently. The value should be set to 0. | This object is implemented as defined in the corresponding MIB files. | 
| 1.3.6.1.4.1.2011.5.25.256.1.4.1.7 | hwConfigPortConfigRole | Integer32 | read-create | This object indicates the configured role of the ring interface. 0x10: common interface. 0x21: rplOwner interface. 0x22: rplNeighbour interface. | The actually supported access is read-only. | 
| 1.3.6.1.4.1.2011.5.25.256.1.4.1.8 | hwConfigPortProtectionSwitch | INTEGER{forcedSwitch(1),manualSwitch(2),idle(65535)} | read-create | This object indicates the protection switching mode, including forced switching and manual switching. If the mode is not set, the default value 65535 is returned. | The actually supported access is read-only. |
