New ER605 Gateway adopted by SDC and within first 24hrs has generated over 24K device logs RE: ARP
The client logs accessed within the SDC for my Site are filled with over 24,000 log entries (generated within the past 24 hours) and all appear to be relevant to just 5 or 6 devices out of the approx 45 connected / managed client devices all with IP-Mac Bindings and DHCP Client Reservations at the Site.
I have verified that the IP-Mac Binding data matches the DHCP Client Reservation data for every client device present at the site. I have also verified that the MAC address data within the system matches the actual MAC addresses of their respective devices. There does not appear to be a reason for the perpetually repeating warning logs.
The ER605 which I installed and configured the previous evening was a much needed replacement a Netgear Wireless Access Point / Router. The now defunct Netgear device had been providing DHCP and Firewall services for the local network, such as it was. At first, I suspected the cause of these log entries could have been related to aging yet still active DHCP leases from the replaced Netgear device which had not yet expired, but which contained different IP information for the given MAC addresses, specifically for those devices referenced within the logs. However, I'm now no longer as certain of that initial assumption as the rate of log generation has not diminished and the new ER605 has been in operation for over 24 hours. Since the lease durations of the previously installed Netgear router's DHCP clients were set with 2 day expiration times, and I believe DHCP clients attempt to renew their leases at 50% of their leases duration and failing that again at 7/8ths of duration then every hour thereafter until renewal or APIPA ... those aging leases should have been reissued by the ER605 by now, since the devices would have at least attempted to contact an authoritative DHCP server for renewal by now. However the rapidly filling logs entries don't appear to reflect that.
I suppose I will know more by this time tomorrow ... since the previously issued DHCP leases would have all expired by then...
Here is an example of some of the repeating log entries:
EDIT: Detailed logging data has been removed from this post as it contained confidential sensitive information and the specific details of the output remain ancillary and
irrelevant to the stated problem as well as for the eventual solution.
Any assistance or insight that anyone could share or provide would be greatly appreciated. I don't know if this is the result of some external influence, a problem with the switch, eap, or router and or a combination of one or more of the same, or if DHCP is glitching etc ... but I'm trying to troubleshoot and discover root cause so that I can effect a working solution and stop these runaway logs from further slowing down my gateway and sdc to a debilitating crawl.
Thanks in advance.
