You can create a logical interconnect group independently of adding an enclosure, or you can edit the logical interconnect group that the appliance creates when you add the enclosure to the appliance. When you add the first enclosure to the appliance, the preliminary logical interconnect group is based on the physical interconnects in that enclosure and is created with the following properties:

•Existing interconnect types in their existing positions•All physical uplink ports disabled except for stacking links

You can edit this logical interconnect group, and when the configuration is complete, an enclosure group is created and associated with this logical interconnect group.

If you assign an enclosure group (which includes a logical interconnect group) to an enclosure in which the interconnects installed in the enclosure do not match the logical interconnect group, each interconnect reports its state as unmanaged. The physical interconnect configuration in the enclosure must match the logical interconnect group before an interconnect can be managed.

To delete a logical interconnect group, you must delete the associated enclosure group.

16.2.5 About SNMP settings

Network management systems use SNMP (Simple Network Management Protocol) to monitor network-attached devices for conditions that require administrative attention. By configuring settings on the Logical Interconnect Groups and Logical Interconnects screens, you can enable third-party SNMP managers to monitor (read-only) network status information of the interconnects.

The SNMP manager typically manages a large number of devices, and each device can have a large number of objects. It is impractical for the manager to poll information from every object on every device. Instead, each agent on the managed device notifies the manager without solicitation by sending a message known as an event trap.

The appliance enables you to control the ability of SNMP managers to read values from an interconnect when they query for SNMP information. You can filter the type of SNMP trap to
