Owner's Manual

• Egress port blocking for links with direct reachability is implemented to prevent duplicate packets and

loops. In DLF topologies, you cannot configure the ingress blocking port over a direct link between

LACP nodes. If DLF uses ingress blocking on the link between LACP nodes, the failure is handled as a

link failure between the nodes forming the multi-node LACP.

• If the direct link between the active fabric nodes forming the LACP group is lost, the group is split into

two groups. The LACP activates one LACP group and deactivates the other group by assigning

different key values. The deactivated group disables the traffic forwarding links from the LACP

neighbor to prevent loops and duplicate packets.

• The highest priority is assigned to the system priority and port priority in the LACP to enable link

selection for the LAG.

NIC Teaming Requirements and Limitations

• Up to 16 ports are supported for a single node.

• You must directly connect each node in the multi-node team to another node. If you have not

established full mesh networks over the nodes, all links from external nodes are blocked.

• Egress port blocking for links with direct reachability is implemented to prevent duplicate packets and

loops. In DLF topologies, you cannot configure the ingress blocking port over a direct link between

the NIC teaming nodes. If DLF uses ingress blocking on the link between NIC teaming nodes, the

failure is handled as a link failure between the nodes.

Mongo Database and Mongoose

Mongo Database

The Dell Active Fabric Controller uses MongoDB for data persistence. For more information about

MongoDB, Dell recommends the following link: http://www.mongodb.org/about/introduction/

Mongoose

Use Sleepy Mongoose to directly access MongoDB data. To access documents using Sleepy Mongoose,

use the following URIs:

• http://<ipAddress>:27080/<database-name>/<table-name>/_find

• http://localhost:27080/sdnc/controller_switch/_find

OpenStack

You can use the AFC as an orchestration tool for OpenStack configurations. This open-source tool

provides a tenant portal for creating networks, servers, and VMs.

The OpenStack configuration used with the Dell Neutron plug-in provides a reference model.

To separate management traffic from the tenant networks, the OpenStack management out-of-band

network uses separate interfaces. The following illustrations depict two possible use cases.
