RS700 is sending BPDU packets only when in AP mode
I have an issue with RS700 where it sends BPDU packets and causes the switch port to put ports into err-disable state, but only when it is set to AP mode. Switch is required to have BPDU Guard enable...
Keep in contact with NG support on this. Won't be anything we can do on the FW side of things.
Only suggestion would be to put in a non managed switch that doesn't require BPDU Guard, something in between the RS in AP mode and your main switch that does require BPDU Guard.
Thanks for the suggestion, I tried a non-managed switch in between and it simply passes the STP packets through and causes the Cisco switch to put the port in err-disable state. I also verified the RS700 is generating the BPDU packets in AP mode by connecting a laptop to the WAN port and capturing a Wireshark trace. It shows the source as the RS700 MAC.
Interestingly, I also have an RS300 that works fine in AP mode (no BPDU packets). Purchased a second RS300 thinking it would work, but it does not. New RS300 has a newer firmware (1.2.7.2) vs the working RS300 that has 1.0.1.90. Firmware 1.0.1.90 is not generating BPDU packets in AP mode. I compared all settings side by side and they are the same (except for SSID). New RS300 will not accept the older 1.0.1.90 firmware.
