HiGig Port Channel Commands

High-Gigabit Ethernet (HiGig) port channels are used to transmit data between internal backplane ports
on line-card (leaf) and switch fabric module (SFM - spine) network processing units (NPUs). You can
configure an SNMP trap to be generated when traffic distribution in a HiGig port channel is uneven.
NOTE: HiGig port channels on the backplane are also referred to as HiGig link bundles in Z9500
documentation and CLI.
On the Z9500, backplane port channels operate as HiGig link bundles to transmit data traffic between
line-card and SFM NPUs. There are 11 line-card and 6 SFM NPUs. The 6 SFM (spine) NPUs comprise the
switch fabric module; the 11 line-card (leaf) NPUs are used across three Z9500 line cards.
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.

Specify a Z9500 SFM (spine) NPU by entering the keyword
sfm and SFM NPU ID. Valid SFM NPU IDs are 0 to 5.
Specify a Z9500 line-card (leaf) NPU by entering the
keyword linecard and line-card slot. Valid slot numbers
are 0 to 2.
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.
