portTrunkArea
DI
On enterprise-class platforms, displays the default port index. The default port index can be
a port swapped area.
The --show trunk option displays the following information:
Trunk Index
Displays the trunk index.
ptA->ptB
ptA indicates the local user port; ptB indicates the remote user port.
sp
Port speed in Gbps.
Bandwidth
The bandwidth (Rx, Tx, and the combined total for Tx+Rx) of the trunk group. Values are
displayed as either bits per second (Bps), kilobits per second (Kbps), megabits per second
(Mbps), or gigabits per second (Gbps), rounded down to the next integer.
Throughput
Displays the throughput (Rx, Tx, and the combined total for Tx+Rx) of the trunk group.
Results are displayed for the previous second. Values are displayed as either bits per
second (Bps), kilobits per second (kbps), megabits per second (Mbps), or gigabits per
second (Gbps), rounded down to the next integer.
%
Displays the percentage of link utilization (Rx, Tx, and the combined total for Tx+Rx) . Even
when the link utilization is 100% , the throughput value will be lesser than the bandwidth
value, due to the 8b/10b encoding and the control words transmitted. For example, the
throughput for an 8 Gbps link at 100% utilization would be approximately 6.8 Gbps.
deskew
The time difference for traffic to travel over each F_Port trunk as compared to the F_Port
trunk with the shortest travel time in the group. The value is expressed in nanoseconds
divided by 10. The firmware automatically sets the minimum deskew value of the shortest
F_Port trunk travel time to 15.
Master
Identifies the master port of the trunk group.
