Abstract: A disclosed method may include (1) identifying a set of field-replaceable units installed on a network device, (2) monitoring the set of FRUs for flapping that renders any of the FRUs temporarily inoperable, (3) detecting at least one flap in which an FRU within the set (A) experiences a fault that renders the FRU temporarily inoperable and (B) subsequently overcomes the fault to resume operability, (4) determining that the FRU is deficient based at least in part on at least one characteristic of the flap detected in connection with the FRU, and (5) performing at least one corrective action that addresses the deficiency of the FRU. Various other systems and methods are also disclosed.

Abstract: An example network device executes a plurality of virtual machines (VMs). The network device is configured to determine to assign a number of Internet protocol (IP) addresses to the plurality of VMs, the number of IP addresses being greater than two, determine a first IP address, determine a range value that is equal to or greater than the number of IP addresses, generate a message according to Duplicate Address Protocol (DAD) including data indicating that the message includes a range of addresses, the data further indicating the first IP address and the range value; and send the message according to DAD via the network interface to one or more network devices to determine whether any IP address in a range starting with the first IP address and through the range value is in use by the one or more network devices.
