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 over subscription. Packets are dropped when they reach the port but before they are sent out. Note: Reducing the packet size or rate of the incoming traffic or configuring GigaStream will resolve this issue.
IfInDiscards	Total Received Discarded Packets Discards are counted in the following cases: ● Traffic arriving at a network port that is not logically connected using a map or map passall. ● Map rules/map rules applied on a network port. ● In packets on a tool port. ● Pause frames.	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 HC Seriesnode 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.
