Abstract: In some implementations, a method is provided. The method may allow a powered device to determine the maximum power available from power supply equipment. The method includes determining the length of a cable connecting the powered device to the power supply equipment based on the resistance of the cable. The method further includes determining the maximum power available to the powered device based on the length of the cable. The powered device may then be operated based on the maximum power available.

Abstract: A method of operating a wireless access point is provided. The method can include connecting with a host and determining whether the host has roamed from the wireless access point to an additional wireless access point. The method can further include activating a tunnel connecting the wireless access point to the additional wireless access point subsequent to determining that the host has roamed from the wireless access point to the additional wireless access point. The method can further include forwarding data packets from the wireless access point to the additional wireless access point via the tunnel. The tunnel can be temporarily created or established based on a configurable timer.

Abstract: Systems and methods are provided herein for an improved method of Zero-Touch Provisioning (ZTP) where a first switch receives a virtual local area network (VLAN) identifier from a second switch, allowing the first switch to reach a dynamic host configuration protocol (DHCP) server. This may be accomplished by a first switch receiving a VLAN identifier from a second switch. The first switch then transmits a DHCP discover message using the VLAN identifier. The first switch then receives reachability information for a ZTP server from the DHCP server. The first switch uses the reachability information to establish a provisioning session between the first switch and the ZTP server.
