Link Bundle Monitoring
Monitoring linked LAG bundles allows traffic distribution amounts in a link to be monitored for unfair
distribution at any given time. A threshold of 60% is defined as an acceptable amount of traffic on a
member link.
distribution at any given time. A threshold of 60% is defined as an acceptable amount of traffic on a
member link.
Links are monitored in 15-second intervals for three consecutive instances. Any deviation within that time
sends Syslog and an alarm event generates. When the deviation clears, another Syslog sends and a clear
alarm event generates.
The link bundle utilization is calculated as the total bandwidth of all links divided by the total bytes-per-
second of all links. If you enable monitoring, the utilization calculation is performed when the utilization
of the link-bundle (not a link within a bundle) exceeds 60%.

Monitoring HiGig Link Bundles
You can monitor the HiGig link bundles that transmit data between internal backplane ports on line-card
(leaf) and switch fabric module (SFM - spine) network processing units (NPUs) and generate a system log
message or SNMP trap when traffic distribution in a link bundle is uneven. Each NPU is a Trident chip.
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.

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.
• 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 link bundles to transmit data.
• An SFM (spine) NPU uses 11 HiGig link bundles, one link bundle to transmit data to each line-card
(leaf) NPU. Each HiGig link bundle in an SFM NPU consists of two HiGig links.
• A line-card (leaf) NPU supports 12 front-end I/O ports and 12 backplane HiGig ports. The 12
backplane links are members of a single HiGig link bundle that connects the line-card NPU to each
SFM (spine) NPU. Two HiGig links in the bundle are used to connect to each SFM NPU.
