Issue/Introduction

Spectrum Trunk Membership requires the device to support the dot3adAggPortAggregateOrIndividual and dot3adAggPortAttachedAggID attributes from the dot3adAggPortTable of the IEEE8 802.3ad MIB.

These attributes are defined in the IEEE8 802.3ad MIB and displayed in the solution.

The attributes defined in the IEEE8 802.3ad MIB:

     dot3adAggPortAggregateOrIndividual OBJECT-TYPE
     SYNTAX TruthValue {
     true(1),
     false(2)
     }
     ACCESS read-only
     STATUS current
     DESCRIPTION
     "A read-only Boolean value indicating whether the
     Aggregation Port is able to Aggregate ('TRUE') or is
     only able to operate as an Individual link ('FALSE')."
     ::= { dot3adAggPortEntry 24 }
     -- 1.2.840.10006.300.43.1.2.1.1.24

     dot3adAggPortAttachedAggID OBJECT-TYPE
     SYNTAX InterfaceIndex (1 .. 2147483647)
     ACCESS read-only
     STATUS current
     DESCRIPTION
     "The identifier value of the Aggregator that this Aggregation
     Port is currently attached to. Zero indicates that the Aggregation
     Port is not currently attached to an Aggregator. This value is read-only."
     ::= { dot3adAggPortEntry 13 }
     -- 1.2.840.10006.300.43.1.2.1.1.13

If port trunking is enabled, the dot3adAggPortAggregateOrIndividual attribute for that port ifIndex will be set to "true" and the dot3adAggPortAttachedAggID attribute will be set to the ifIndex of the trunk port for that port ifIndex.

Environment

Release:
Component: SPCDIS

Resolution

Use OneClick MIB Tools to verify the support of the dot3adAggPortAggregateOrIndividual and dot3adAggPortAttachedAggID attributes for a particular device. If these attributes are not supported, contact the device vendor.
