Addendum

Field Description
Alarm State Indicates whether an alarm is
generated if overutilization of the port
channel occurred. Possible values are
Active and Inactive
Interface Slot and port number, and the type of
the member interface of the port
channel
Line Protocol Indicates whether the interface is
administratively up or down
Utilization (In Percent) Traffic usage in percentage of the
packets processed by the particular
member interface
Example
Dell#show link-bundle-distribution port-channel 1
Link-bundle trigger threshold - 60
LAG bundle - 1 Utilization[In Percent] - 0 Alarm
State - Inactive
Interface Line Protocol Utilization[In
Percent]
Te 0/5 Up 0
Te 0/13 Up 0
Setting Up a Threshold for Utilization of High-Gigabit
Port Channels
This functionality is supported on the Z9000 platform.
You can configure a mechanism to monitor a backplane high-Gigabit Ethernet port channel and
generate a system logging message or an SNMP trap when the traffic distribution and the handled data
packets on the bundle is uneven or inconsistent. The formula or the computation parameter to
determine the uneven or the unequal distribution of traffic is predefined and at a particular point in time,
if you enable the capability to examine the efficiency of the member links of a port channel bundle, such
an unbalanced segregation of traffic across the member links of the high-Gigabit Ethernet bundle is
indicated using alarms and traps. Also, when the traffic is resumed to be handled in an equalized, proper
manner, a notification using alarms and SNMP traps is generated.
The Dell Networking OS already contains the functionality to monitor the performance and traffic-
handling of virtual interfaces created as LAG bundles and ECMP configured on physical user ports. You
can now verify the traffic-distribution and processing of high-Gigabit Ethernet port channels. Trunk
groups for backplane higig link bundles between leaf and spines are created. For trunk groups to be
provisioned on Z9000 platforms, 1 trunk group (hiGig link bundle) on each leaf unit is created and 4 trunk
groups on each spine unit are created. As a result, a total of 12 trunk groups are present on the 2 spine
and 4 leafs of Z9000 platform.
Based on the hashing algorithm that is specified, traffic in the trunk groups are distributed. It is possible
that an unequal or imbalanced traffic distribution in higig trunk groups might occur. When you configure
the method to monitor the high-Gigabit Ethernet port channel and trunk groups, you can view and
analyze the unequal traffic split and flow in the trunk groups and take corrective action as appropriate.
