Description

This article provides information on how to read the relationship between an AE bundle and its member ports via MIB.

Symptoms

Some customers want to know if it is possible to read the relationship between an AE bundle and its member ports via MIB and how to do so; if possible.

Solution


The following example is of an AE bundle and its two member port on the MX- series platform:

lab@MX480-d-re0> show snmp mib walk ifDescr | grep ae0
ifDescr.625 = ae0
ifDescr.635 = ae0.0

lab@MX480-d-re0> show snmp mib walk ifStackStatus.635
ifStackStatus.635.589 = 1
ifStackStatus.635.590 = 1

lab@MX480-d-re0> show snmp mib walk ifDescr | grep 589
ifDescr.589 = ge-1/0/0.0

lab@MX480-d-re0> show snmp mib walk ifDescr | grep 590
ifDescr.590 = ge-1/0/1.0

lab@MX480-d-re0>
This complies with the definition of the Object ifStackTable , as defined in RFC 2863 . The Interfaces Group MIB is as follows:

ifStackTable OBJECT-TYPE
   SYNTAX SEQUENCE    OF IfStackEntry
   MAX-ACCESS         not-accessible
   STATUS            current
   DESCRIPTION

"The table contains information on the relationships between the multiple sub-layers of network interfaces. In particular, it contains information on which sub-layers run 'on top of' which other sub-layers, where each sub-layer corresponds to a conceptual row in the ifTable. For example, when the sub-layer with ifIndex value x runs over the sub-layer with ifIndex value y, then this table contains:

ifStackStatus.x.y=active
