Display Fabric Statistics for All Ports
Using the Fabric Statistics page, you can view the statistics associated with the port types. If there are packet drops in the ports, click on the port and drill down further to investigate the cause of the packet drops.
To view the Fabric Statistics page:
| 1. | On the left navigation pane, click  , and then select Physical > Nodes. and click on a GigaVUE node. |
| 2. | Select Ports > Ports > Fabric Statistics. |
Table 1: Fabric Statistics Definitions describes the columns in the Fabric Statistics table.

Unicast Packets Rx |
Total unicast packets received |
Excludes multicast packets, broadcast packets, packets with FCS/CRC errors, MTU exceeded errors, oversize packets, and pause packets. |
|
Unicast Packets Tx |
Total unicast packets transmitted |
Excludes multicast packets, broadcast packets, packets with FCS/CRC errors, MTU exceeded errors, oversize packets, and pause packets. |
|
Packets/sec Rx |
Total packets received per second Excludes multicast packets, broadcast packets, packets with FCS/CRC errors, MTU exceeded errors, oversize packets, and pause packets. |
Excludes packets with FCS/CRC errors. |
|
Packets/sec Tx |
Total packets transmitted per second |
Excludes multicast packets, broadcast packets, packets with FCS/CRC errors, MTU exceeded errors, oversize packets, and pause packets. |
|
Octets/sec Rx |
Total bytes received per second This indicates the rate of incoming bytes in the last second. |
|
|
Octets/sec Tx |
Total bytes transmitted per second This indicates the rate of incoming bytes in the last second. |
|
|
Bits/sec |
Total bits transmitted per second. |
|
|
Utilization Rx |
Percentage of port utilization by packets received |
|
|
Utilization Tx |
Percentage of port utilization by packets transmitted |
|
|
Link Speed |
Maximum link speed of the port |
|
|
Type |
Type of port |
|
|
Octets Rx |
Total bytes received Includes all valid and error frames with the exceptions noted in the adjacent columns. |
Excludes undersize frames. |
|
Tx drop count |
Total packets dropped in the Tx packets. |
|
|
Tx drop percentage |
Total packets dropped in the Tx packets in percentage. |
|
|
Error count |
The count of error packet received. |
|
|
Error percentage |
The percentage of error packets received. |
|
|
Octets Tx |
Total bytes transmitted Includes all valid and error frames with the exceptions noted in the adjacent columns. |
Excludes undersize frames. |
|
Non-unicast Packets Rx |
Total Broadcast and Multicast packets received |
|
|
Non-unicast Packets Tx |
Total Broadcast and Multicast packets transmitted |
|
|
Rx Drops count |
Total received packets dropped |
Packets are dropped when a tool port’s bandwidth is exceeded due to oversubscription. Packets are dropped when they reach the tool port but before they are sent out. |
|
Tx Drops count |
Total transmitted packets dropped |
Packets are dropped when a tool port’s bandwidth is exceeded due to oversubscription. Packets are dropped when they reach the tool port but before they are sent out. |
|
Discards Rx |
Total received packets discarded |
This counter increments when a packet is discarded at a tool port due to a tool port map rule. |
|
Discards Tx |
Total transmitted packets discarded |
This counter increments when a packet is discarded at a tool port due to a tool port map rule. |
|
Error Rx |
Total error packets received Error packets include undersize, FCS/CRC, MTU exceeded, fragments, and oversize packets.All packets that list under this counter are discarded and not processed further. |
Excludes oversize packets without FCS/CRC. Packets larger than the MTU setting arriving on a network port are counted twice in the counter. So 1000 oversize packets would show up as 2000. This double-counting only happens with Oversize error packets. |
|
