Command Information
Request Information
| Byte | Data Field |
|---|---|
| NetFn | 30h |
| CMD | 90h |
| 1 | Sub command, subcommand = 01h |
| 2 | FRU Device ID |
| 3 | MAC ID NOTE: If the request data contains the fourth byte, the MAC ID indicates the sequence number of the interface of the same type. That is, the MAC ID of each type of interface is numbered from 1.If the request data does not contain the fourth byte, the MAC ID indicates the sequence number of multiple MAC addresses on the same FRU. That is, different interface types are numbered in a unified manner. |
| (4) | Interface Type 1=Base Interface 2=Fabric Interface 3=Front panel network port 4: external expansion network port; 5: WWNNN 6=WWPN 16=Update Channel Interface Others reserved NOTE: This byte is optional. When this byte exists, the MACID of the third byte is the sequence number of the same interface type. |
Response Information
| Byte | Data Field |
|---|---|
| 1 | Completion Code |
| 2 | FRU Device ID |
| 3 | MAC ID NOTE: If the request data does not contain the fourth byte, MACID indicates the sequence number of multiple MAC addresses on the same FRU. (Network ports of different types are numbered in a unified manner. For example, 1 and 2 may be Base network ports, 3 and 4 may be Fabric network ports, and 5 indicates WWNNs and 6 indicates WWPNs.)If the request data has the fourth byte, MACID indicates the sequence number of the same interface type. |
| 4 | Interface Type 1=Base Interface 2=Fabric Interface 3=Front panel network port 4=External expansion network port 5=WWNN 6=WWPN 16=Update Channel Interface Others reserved |
| (5) | Next MAC ID: indicates the next MAC ID of the same interface. If there is no next MAC ID, this field is set to 0XFF. NOTE: This byte exists only when the request data contains the fourth byte. |
| MAC | |
| 5:10 Or 6:11 | MAC Address: 6 bytes (EUI-48 specification) NOTE: When the Next MAC ID exists, the value range of this field is (6:11). |
| MAC | |
| 5:12 Or 6:13 | MAC address: 8 bytes (EUI-64 specification) NOTE: If the Next MAC ID exists, the value of this field ranges from 6 to 13. |
| WWNN & WWPN | |
| 5:12 Or 6:13 | WWN (8 Bytes) NOTE: If the Next MAC ID exists, the value of this field ranges from 6 to 13. |
