Yup. I usually see this when the router is locked up or just "dumb". sometimes you can see it when the router has an ethernet link but is brain dead....radio will show a ethernet link but no MAC shows in the bridge table. Usually a power cycle of the router will fix ----- Original Message ----- From: Christopher Gray To: [email protected] Sent: Thursday, December 28, 2017 9:07 AM Subject: Re: [AFMUG] PMP100 No Customer MAC in Bridging Table?
Resolved somehow. There are only 2 customers on this old AP. Customer #2 shuts off their router every night and it was off during troubleshooting... when they turned their router on this morning, it's MAC address showed up and the problem for Customer #1 went away right then and started showing a MAC in the system. [I went through various troubleshooting steps, had them connect a computer directly, and still no MAC address, but DHCP requests were coming through. Radio said 100 Mbps on Ethernet the whole time.] Thank you for the help. On Thu, Dec 28, 2017 at 9:57 AM, Jay Weekley <[email protected]> wrote: I agree with Nate. I assume that if DHCP requests are getting through to your router there is an ethernet link on the radio. For trouble shooting I have the customer move the cable from the radios power supply to another port on their router or directly to a computer to see if a MAC shows up in the bridging table. You may try lowering the link speed to 10 megabit but I can't remember if that has helped or not.

I usually see 3x addresses in the Bridging Table, 2x for the radio, and 1x for the customer, but I'm just seeing the 2x radio MACs even though customer DHCP requests are making it through to my router. This just showed up today, as the customer router stopped getting an IP address (the router sees the request for IP, offers it, but it never binds). Any ideas for kicking this back into functioning status? --- This email has been checked for viruses by AVG. http://www.avg.com
