| Parameter | Description |
|
Interval:<2 sec> | The interval (in seconds) that the table is updated. The default is 2 | |||
|
| seconds. |
|
|
RX Frames | Received packets. |
|
| |
CRC Error | For 10 Mbps ports, the counter records CRC errors (FCS or alignment | |||
|
| errors). For 100 Mbps ports, the counter records the sum of CRC | ||
|
| errors and code errors (frames received with rxerror signal). | ||
Undersize | The total number of frames received that were less than 64 octets long | |||
|
| (excluding framing bits, but including FCS octets) and were otherwise | ||
|
| well formed. |
|
|
Oversize | The total number of frames received that were longer than 1518 octets | |||
|
| (excluding framing bits, but including FCS octets) and were otherwise | ||
|
| well formed. |
|
|
Fragments | The total number of frames received that were less that 64 octets in | |||
|
| length (excluding framing bits, but including FCS octets) and had | ||
|
| either an FCS or an alignment error. | ||
Jabber | The total number of frames received that were longer than 1518 octets | |||
|
| (excluding framing bits, but including FCS octets), and had either an | ||
|
| FCS or an alignment error. |
|
|
Drop Pkts | The total number of events in which packets were dropped due to a | |||
|
| lack of resources. |
|
|
TX Frames | Transmitted packets. |
|
| |
ExDefer | The number of frames for which the first transmission attempt on a | |||
|
| particular interface was delayed because the medium was busy | ||
CRC Error | For 10 Mbps ports, the counter records CRC errors (FCS or alignment | |||
|
| errors). For 100 Mbps ports, the counter records the sum of CRC | ||
|
| errors and code errors (frames received with rxerror signal). | ||
Late Coll. | Late Collisions. The number of times that a collision is detected later | |||
|
| than 512 | ||
Ex. Coll. | Excessive Collisions. The number of frames for which transmission | |||
|
| failed due to excessive collisions. | ||
Single Coll.* | Single Collision Frames. The number of successfully transmitted | |||
|
| frames for which transmission is inhibited by more than one collision. | ||
Coll. | An estimate of the total number of collisions on this network segment. | |||

Port Packet Analysis
The Packet Analysis screen displays the size of packets received or transmitted by a given switch port. In addition, statistics on the number and rate of unicast, multicast, and broadcast packets received by the switch are displayed.
