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.

Port ID

Port ID in the format <box id/slot id/port id>

 

Alias

Alias of the port

 

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.

Error Tx

Total error packets transmitted

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.
