Abstract: A fault locating method includes: receiving, by a first network device, a fault information packet flooded by another network device in a network, where each fault information packet includes statistical information about an interior gateway protocol packet of the network device sending the fault information packet, and the statistical information of each network device includes a statistical result on one or more key performance indicators KPIs of the network device; and determining, based on statistical information of the first network device and the statistical information of the another network device, a network device on which a fault occurs in the network. According to the method, the fault information packet flooded by the network device is received, so that information required for fault locating, that is, the KPI of the network device, can be quickly collected. This facilitates a fault locating process and reduces a fault locating time.

Abstract: A bandwidth configuration method and a related device are disclosed. An electronic device first determines bandwidth configuration schemes of N AP groups, and then adjusts the bandwidth configuration scheme of the AP group based on a physical topology similarity between the AP groups. When physical topologies of two AP groups are similar, if bandwidths of two APs at corresponding physical locations in the two AP groups are different, the electronic device determines a larger value of the bandwidths of the two APs as the bandwidths of the two APs.

Abstract: In the field of communication technologies or the field of artificial intelligence, a terminal scanning method, system, and apparatus, an electronic device, and a storage medium may be provided. In the method, an AP determines, based on communication feature information of a terminal that accesses the AP, whether a neighboring AP needs to scan the terminal; and if yes, the AP notifies the neighboring AP to scan the terminal. This reduces a quantity of times that the neighboring AP scans the terminal, and reduces calculation overheads of the neighboring AP.
