Description: Brocade Foundry Link Aggregation Group MIB providing LAG membership, LACP statistics, and trunk port management objects for FastIron switches.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is FOUNDRY-LAG-MIB?

FOUNDRY-LAG-MIB is a Brocade (formerly Foundry Networks) enterprise MIB that manages Link Aggregation Group (LAG/trunk) configuration and statistics on FastIron and NetIron (MLX/XMR) switches, superseding the older FOUNDRY-SN-LAG-MIB starting with release 4.1.0. It exposes configuration data such as LAG membership, admin status, trunk type/threshold, and LACP timeout, alongside status data like primary port and active port count for each aggregate. As a monitoring tool it's used chiefly for software/configuration-state health of link aggregation — confirming a trunk group's admin status is up, its expected member ports are active, and LACP timers are configured as intended, which indirectly reflects link/interface hardware status. It works alongside the standard IETF IF-MIB (ifIndex references) and Foundry's own interface MIBs since LAG members are indexed by interface. It's deployed on Brocade/Foundry FastIron and MLX/XMR switches wherever multiple physical links are bonded into logical trunks for redundancy or bandwidth. Engineers can download the FOUNDRY-LAG-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in FOUNDRY-LAG-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Brocade (Foundry) FastIron switch
Brocade NetIron MLX/XMR router/switch

Monitoring Examples

An admin would poll fdryLinkAggregationGroupTable/fdryLinkAggregationGroupEntry, reading fdryLinkAggregationGroupAdminStatus and fdryLinkAggregationGroupPortCount for a given fdryLinkAggregationGroupName to confirm the trunk is enabled and all expected member ports (from fdryLinkAggregationGroupIfList) are participating. A drop in fdryLinkAggregationGroupPortCount below the configured member count, or a change in fdryLinkAggregationGroupPrimaryPort, would indicate a failed or flapping link within the LAG.

What Can Be Monitored

LAG/trunk admin status
LAG member port count
primary port selection
LACP timeout setting
trunk type and threshold

NTF fdryTrapLagDeployed	1.3.6.1.4.1.1991.0.1204			The SNMP trap that is generated when a LAG is deployed.

fdryLinkAggregationGroupMIB	1.3.6.1.4.1.1991.1.1.3.33			Management Information Base module for link aggregate group configuration and statistics. Link aggregation group is a new concept of trunk and this MIB is replacing FOUNDRY-SN-LAG-MIB in MLX/XMR products starting release 4.1.0. Copyright 1996-2010 Brocade Communications Systems, Inc.

fdryLinkAggregationGroupEntry	1.3.6.1.4.1.1991.1.1.3.33.1.1.1		not-accessible	An entry of the Link Aggregate Group table.
STR fdryLinkAggregationGroupName	1.3.6.1.4.1.1991.1.1.3.33.1.1.1.1	DisplayString	not-accessible	Name of a LinkAggregationGroup.
INT fdryLinkAggregationGroupType	1.3.6.1.4.1.1991.1.1.3.33.1.1.1.2	INTEGER	read-create	LinkAggregationGroup type.
INT fdryLinkAggregationGroupAdminStatus	1.3.6.1.4.1.1991.1.1.3.33.1.1.1.3	INTEGER	read-create	The desired deplyed state of this LinkAggregationGroup entry. This is not the operational status. Refer to ifTable for the operational status. deploy(1).............deploy the LAG and set to LACP active if dynamic LAG. deployPassive(2)..deploy the LAG and set to LACP passive if dynamic LAG. undeploy(3).........undeploy the LAG if no more than 2 ports are enabled. undeployForced(4)..undeploy the LAG regardless number of ports enabled. This is a write-only value. In particular, a row cannot be deployed until the corresponding instances of fdryLinkAggregationGroupIfList has been set.

To create a row in this table, a manager must set this object to createAndGo(4) together with the setting of fdryLinkAggregationGroupType. After that the row status becomes active(1) regardless the LAG entry is deployed or not. To deploy the LAG entry, set the corresponding instance of fdryLinkAggregationGroupAdminStatus to deployActive or deployPassive.
