Displaying Port Statistics
Use the show port stats command to display port statistics. The output of the command is as follows:
(config) # show port stats port-list 7/3/x25..x26
Counter Name Port: 7/3/x25 Port: 7/3/x26

This example is for a port pair. Port 7/3/x25 is a network port (with incoming bytes/packets). Port 7/3/x26 is a tool port (with outgoing bytes/packets). In the output, a zero means no traffic is flowing.
Starting in software version 4.3, the show port stats command also displays statistics for GigaSMART engine ports.
The following table describes port statistics:
Counter |
Definition |
Notes |
||||||||||||
IfInOctets |
Total Received Bytes Includes all valid and error frames with the exceptions noted in the adjacent columns. |
Excludes undersize frames. |
||||||||||||
IfInUcastPkts |
Total Received Packets Excludes multicast packets, broadcast packets, packets with FCS/CRC errors, MTU exceeded errors, oversize packets, and pause packets. |
Excludes packets with FCS/CRC errors. |
||||||||||||
IfInNUcastPkts |
Total Received Broadcast and Multicast packets |
|
||||||||||||
IfInPktDrops |
Total Received Dropped Packets |
Packets are dropped when a network port’s bandwidth is exceeded due to oversubscription. Packets are dropped when they reach the port but before they are sent out. |
||||||||||||
IfInDiscards |
Total Received Discarded Packets Discards are counted in the following cases:
|
Refer to Reasons for IfInDiscards for a discussion of why this counter may be incrementing. |
||||||||||||
IfInErrors |
Total Received Error Packets This indicates hardware detected errors. Error packets include undersize, FCS/CRC, MTU exceeded, fragments, and oversize packets. All packets that list in the IfInErrors 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 ifInErrors counter. So, 1000 oversize packets would show up as 2000 ifInErrors. This double-counting only happens with Oversize error packets. |
||||||||||||
IfInOctetsPerSec |
Total Received Bytes Per Second This indicates the rate of the incoming bytes in the last second. |
|
||||||||||||
IfInPacketsPerSec |
Total Received Packets Per Second This indicates the rate of the incoming packets in the last second. |
|
||||||||||||
IfOutOctets |
Total Transmitted Bytes Error packets are not transmitted, so they are not counted here. |
|
||||||||||||
IfOutUcastPkts |
Total Transmitted Packets Error packets are not transmitted, so they are not counted here. In addition, multicast and broadcast packets are not counted here. |
|
||||||||||||
IfOutNUcastPkts |
Total Transmitted Broadcast and Multicast Packets |
|
||||||||||||
IfOutDiscards |
Transmitted Packets Discarded This counter increments when a packet is discarded at a tool port due to a tool port map rule. |
|
||||||||||||
IfOutPktDrops |
Total Transmitted Dropped Packets |
Packets are dropped when a tool or hybrid port’s bandwidth is exceeded due to oversubscription. Packets are dropped when they reach the port but before they are sent out. |
||||||||||||
IfOutErrors |
Transmitted Error Packets Error packets seen on GigaVUE H Series node input port are not transmitted to a tool port. |
|
||||||||||||
IfOutOctetsPerSec |
Total Transmitted Bytes Per Second This indicates the rate of the outgoing bytes in the last second. |
|
||||||||||||
IfOutPacketsPerSec |
Total Transmitted Packets Per Second This indicates the rate of the outgoing packets in the last second. |
