|
| Tx Packet |
|
|

|
|
|
| Rx Packets | This field displays the number of packets received. |
|
|
|
| Multicast | This field shows the number of good multicast packets received. |
|
|
|
| Broadcast | This field shows the number of good broadcast packets received. |
|
|
|
| Pause | This field shows the number of 802.3x Pause frames received. |
|
|
|
