| DESCRIPTION |
| "This object contains an OBJECT IDENTIFIER |
| which identifies the chipset used to |

| interfaces are typically built out of |
| several different chips. The MIB implementor |
| is presented with a decision of which chip |
| to identify via this object. The implementor |
| should identify the chip which is usually |
| called the Medium Access Control chip. |
| If no such chip is easily identifiable, |
| the implementor should identify the chip |
| which actually gathers the transmit |
| and receive statistics and error |
| indications. This would allow a |
| manager station to correlate the |
| statistics and the chip generating |
| them, giving it the ability to take |
| into account any known anomalies |
