Smarts IP: Aggregate Port does not show ComposedOf

Products

• VMware Smart Assurance

Issue/Introduction

Symptoms:


The question was asked regarding why does Smarts IP not show the ComposedOf Properties for an Aggregate Port.

When we enabled the discovery debug on a Juniper Router, we can see that Smarts does find the underlying ports.

 In this case ports index 34 and 35 that share the same Interface Alias "taa-unman"

Environment

VMware Smart Assurance - SMARTS

Cause

Representation of Etherchannel The discovered etherchannel connections are represented by the following classes:

  AggregatePort   This class represents the etherchannel adapter in IP Availability Manager. It is defined as the logical grouping of network adapters.

  AggregateLink   This class represents the logical links between AggregatePorts. During post processing, all the AggregatePorts instances are retrieved from the discovered topology. If the constituents ports of the AggregatePort are connected and the peer ports of those constituent ports are associated with AggregatePort, then AggregateLink is created between those two AggregatePort.

The EMC Smarts IP Manager Reference Guide and the EMC Smarts IP Manager Release Notes provide more information.

Identifying AggregationPorts through CLI

You can identify AggregatePorts and figure out ports that are part of an aggregation by running the CLI command:

show port-channel summary

Resolution

The underlying ports for an Aggregate Port are not considered as separate instances.  The monitoring in Smarts is done on the Aggregate Port only and Smarts will show only the Aggregate Port in the topology.
