It is just an informational message related to directly connected hosts in the ARP table. The switch keeps a list of directly connected hosts that is constantly updating. When the switch reaches more than 200 directly connected hosts in the ARP table, this kind of message starts to appear. At this point the switch will clear part of the ARP table in order to keep at most 180 used addresses. As previously mentioned, this is not causing any problems on the switch. The "ip caused the problem" part is poor phrasing and only means that the table reached the maximum number of addresses. The switch should function fine.
By default the switch will only route for 200 hosts. The default support table entry value is 200 for the hosts, 64 for the static routes, and 32 for the IP interfaces.
Use the command config#system resources routing 64 400 32 to increase the support table for hosts.
Configuration is now:
Parameters Current value After reboot Value
-------------- ---------------- -------------------
