The activity shown in the network log illustrates numerous ARP (Address Resolution Protocol) requests for various IP addresses. This pattern is indicative of a sweep of available hosts on the local subnet. ARP requests are sent out to determine which MAC addresses correspond to specific IP addresses, and the wide range of IP addresses queried here suggests a scan to identify which IP addresses are in use. No specific indication of an attack on the CAM table, wireless disassociation, or gateway impersonation is evident in the log.
