The present disclosure relates to simultaneous operation of Wi-Fi access points in a super cell mode and a standalone mode and controlling connectivity of end terminals thereto. In one aspect, a method includes receiving a configuration for a group of access points operating within a network, the configuration allowing each access point of the group to operate in a super cell mode over a shared frequency channel and a standalone mode over a non-shared frequency channel. The method further includes determining, for an end terminal, whether the end terminal is to connect to the network over the shared frequency channel or the non-shared frequency channel based on a network policy to yield a determination; and controlling connectivity of the end terminal to at least one access point of the group of access points over the shared frequency channel or the non-shared frequency channel based on the determination.

In one embodiment, a network device along a path in a network receives a schedule that controls when the networking device is to insert telemetry data into data traffic passing through the networking device. The networking device generates the telemetry data for insertion into the data traffic passing through the networking device. The networking device inserts, according to the schedule, the telemetry data into a particular packet of the data traffic passing through the networking device. The networking device sends the particular packet to a next hop along the path in the network.

A method is provided that is performed in a wireless network to detect a rogue wireless device. The method comprises detecting a suspect wireless device in the wireless network based on messages transmitted by the suspect wireless device using a first Media Access Control (MAC) address that is also used by a valid wireless device in the wireless network. When a suspect wireless device is detected, the method next includes sending to the valid wireless device in the wireless network a request configured to cause the valid wireless device to change its MAC address. After the valid wireless device has changed its MAC address, the method involves observing messages transmitted by the suspect wireless device in the wireless network. The method then includes determining that the suspect wireless device is a rogue device when the suspect wireless device continues to transmit messages using the first MAC address.

In one embodiment, a gateway to a Layer-3 network forms a first Layer-2 tunnel between the gateway and a first wireless access point (AP) that communicates wirelessly with a first mobile node of a mobile system (MS) via a first wireless connection. The gateway generates a mapping that associates an onboard device of the MS with the first AP and an identifier for the MS, based on traffic conveyed via the first Layer-2 tunnel and associated with the onboard device, the traffic comprising a header that indicates the identifier for the MS. The gateway receives, from a second AP, an indication that the MS is roaming from the first wireless connection to a second wireless connection, the indication including the identifier for the MS. The gateway updates the mapping to associate the onboard device of the MS with a second AP, based on the indication that the MS is roaming.
