Reference Guide

Line-card NPUs are numbered as follows:
● Line-card slot 0 uses three NPUs numbered 0 to 2.
● Line-card slot 1 uses four NPUs numbered 0 to 3.
● Line-card slot 2 uses four NPUs numbered 0 to 3.
SFM NPUs are numbered 0 to 5.
Line-card and SFM NPUs use HiGig port channels to transmit data.
● An SFM NPU uses 11 HiGig port channels, one port channel to transmit data to each line-card NPU. Each HiGig port channel
in an SFM NPU consists of two HiGig links.
● A line-card NPU supports 12 front-end I/O ports and 12 backplane HiGig ports. The 12 backplane links are members of a
single HiGig port channel that connects the line-card NPU to each SFM NPU. Two HiGig links in the port channel are used to
connect to each SFM NPU.
clear hardware hg-stats
Clear traffic statistics from a HiGig port in a HiGig link bundle/port channel on a line-card or switch fabric module (SFM) NPU.
Z9500
Syntax
clear hardware {sfm npu-id | linecard slot} hg-stats {port hg-port—number |
unit npu-id port hg-port—number}
Parameters
sfm npu-id Specify a Z9500 SFM (spine) NPU by entering the keyword sfm and SFM NPU ID.
Valid SFM NPU IDs are 0 to 5.
linecard slot Specify a Z9500 line-card (leaf) NPU by entering the keyword linecard and line-
card slot. Valid slot numbers are 0 to 2.
hg-stats {port
hg-port-number |
unit npu-id port
hg-port-number }
Enter the keyword hg-stats to clear HiGig port statistics.
For an SFM NPU HiGig link bundle, specify only a HiGig port number. Valid SFM hg-
port-number values are 1 to 22.
For a line-card NPU HiGig link bundle, specify an NPU ID and a HiGig port number.
Line-card NPUs range from 0 to 3. Line-card HiGig port numbers range from 50 to
61.
