Abstract: Methods, apparatuses, and computer program products for telemetry-based network switch configuration validation are disclosed. An analytics engine captures a first network snapshot including telemetry data received from one or more network switches in a first state. Upon receiving a notice indicating that a network configuration change has been applied, the analytics engine initiates a timer in response to receiving the notice. The analytics engine captures, in response to expiration of the timer, a second network snapshot including telemetry data received from the one or more network switches in a second state and compares the first network snapshot and the second network snapshot. In dependence upon the comparison of the first network snapshot to the second network snapshot, the analytics engine validates the network configuration change.

Abstract: In one embodiment, an apparatus includes a processing circuit and logic integrated with and/or executable by the processing circuit. The logic is configured to cause the processing circuit to handle Internet Group Membership Protocol (IGMP) messages received from other devices in a network. Also, the logic is configured to cause the processing circuit to create a general query solicit (GQS) message configured to solicit a general query (GQ) from a multicast snooping querier coupled with the apparatus. The GQS message causes the multicast snooping querier to send out a general query (GQ) message on all ports in response to receiving the GQS message. The GQ message is configured to solicit port information and group membership information from each IGMP switch in the network. Other systems, methods, and computer program products are described in more embodiments.

Abstract: An apparatus includes a local compute node connected to a first networking switch by a direct local link. The first switch reduces its priority in response to determining that that the first networking switch is currently unable to establish the bi-directional communication with the local compute node through the direct local link. If the reduced priority of the first networking switch is greater than a priority of each of at least one additional networking switch in a cluster, then the first networking switch operates as a master networking switch for the cluster. If the reduced priority of the first networking switch is less than the priority of any of the at least one networking switch, then the first networking switch operates as a standby networking switch and one of the atleast one additional networking switch having the highest priority is operated as the master networking switch for the cluster.

Abstract: An apparatus includes a local compute node and a first networking switch. The first switch determines whether bi-directional communication is established with the compute node via a direct local link. A message received from an additional networking switch through an inter-switch link indicates whether the additional switch has its additional access/uplinks enabled. The first switch enables first access/uplinks in response to determining that the first switch has currently established bi-directional communication with the compute node and that the received message indicates that the additional networking switch has its additional access/uplinks disabled. The first networking switch disables the first access/uplinks on the first switch in response to determining that the first switch is currently unable to establish bi-directional communication with the compute node and/or receiving a message indicating that the additional networking switch has its additional access/uplinks enabled.

Abstract: A control channel for routing management messages to or from an OpenFlow controller is separated from a reserved port within a data channel for routing unknown data packets to or from the OpenFlow controller. The port may be reserved by setting a reserved port flag. A packet routing table may include a table miss entry that indicates the unknown packets should be routed via the reserved port. By utilizing the reserved port to route unknown packets, the unknown packets do not traverse into the control channel, and the separation of the OpenFlow control channel from the OpenFlow data channel is enhanced.
