Using the IEEE 802.3ad Link Aggregation MIB

Using the IEEE 802.3ad Link Aggregation MIB

The IEEE 802.3ad Link Aggregation Control Protocol (LACP) enables the bundling of physical interfaces on a physical device to achieve more bandwidth than is available using a single interface. This feature introduces IEEE 802.3ad Link Aggregation (LAG) MIB support in Cisco IOS XE software. The LAG MIB supports the management of interfaces and ports that are part of an LACP port channel and is accessed by a Simple Network Management Protocol (SNMP) manager application.

Finding Feature Information

Your software release may not support all the features documented in this module. For the latest feature information and caveats, see the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the Feature Information Table at the end of this document.

Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to www.cisco.com/​go/​cfn. An account on Cisco.com is not required.

Prerequisites for Using the IEEE 802.3ad Link Aggregation MIB

  • Link aggregation must be configured using the LACP command-line interface (CLI) commands before the MIB tables can be accessed.
  • LACP must be supported in the image.

Information About Using the IEEE 802.3ad Link Aggregation MIB

IEEE 802.3ad LAG MIB

The IEEE 802.3ad LAG MIB supports the management of interfaces and ports that are part of an LACP port channel. No specific commands are used to enable the MIB; access is through an SNMP manager application. For information about using SNMP in Cisco IOS XE software, see the “Configuring SNMP Support” chapter of the Cisco IOS XE Network Management Configuration Guide, Release 2.

Configuration and Management of LACP bundles

To use the LAG MIB, it is important to know how LACP bundles are configured and managed. For more information about LACP bundles, see the "Configuring IEEE 802.3ad Link Bundling" feature guide.

LAG MIB Table Object Definitions

This section lists the MIB objects and tables that are supported as part of this feature.

dot3adTablesLastChanged Object

The dot3adTablesLastChanged object indicates the time of the most recent change to the dot3adAggTable, dot3adAggPortListTable, or dot3adAggPortTable.

dot3adAggTable

The dot3adAggTable (Aggregator Configuration table) contains information about every aggregator that is associated with a system. Each LACP channel in a device occupies an entry in the dot3adAggTable. Some objects in the table have restrictions, which are described with the object. The objects are described in the table below.

Table 1 Aggregator Configuration Table Objects

dot3adAggPortListTable

The dot3adAggPortListTable (Aggregation Port List table) contains a list of all the ports associated with each aggregator. Each LACP channel in a device occupies an entry in the table. The objects are described in the table below.

Table 2 Aggregation Port List Table Objects

Object

Maximum Access/Description

dot3adAggPortListPorts

Write access not supported.

dot3adAggPortTable

The dot3adAggPortTable (Aggregation Port table) contains LACP configuration information about every aggregation port associated with a device. Each physical port in a device occupies an entry in the dot3adAggPortTable. The objects are described in the table below.

Table 3 Aggregation Port Table Objects
