show interface pfc
Displays the PFC configuration applied to ingress traffic on an interface, including priorities and link delay.
Syntax
show interface port-type slot/port[/subport] pfc {summary | statistics | detail
| buffer-threshold}
Parameters
port-type slot/
port[ /subport ] pfc
Enter the port-type slot and port PFC information. Enter the subport number if a port is
fanned-out into 10G ports.
{summary |
statistics | detail |
buffer-threshold}
Enter the keyword summary for a summary list of results or enter the keyword detail
for a full list of results. Enter the keyword statistics to view pfc statistics. Use the
keyword buffer-threshold to display the buffer threshold details.
NOTE: This command also enables you to view information corresponding to a range of ports.
However, for Open Networking (ON) platforms the notation for specifying port range in the
command is different from how you specify in non-ON platforms.
• For non-ON platforms, you can specify multiple ports as slot/port-range. For example, if you want to
display information corresponding to all ports between 1 and 4, specify the port range as show interfaces
interface-type 1/1 - 4.
• For ON platforms, you can specify multiple ports as slot/port/[subport] - slot/port/
[subport]. For example, if you want to display information corresponding to all ports between 1 and 4,
specify the port range as show interfaces interface-type 1/1/1 - 1/1/4.
