I am in need of some help. I have a new mountain-top AP installation that I am serving with an 18 GHz PTP820S link, with two 3.65 GHz PMP450i AP's. I use Extreme Networks Summit series switches, and use their EAPS protocol (Ethernet Automatic Protection Switching) for a backup loop for managment (instead of Spanning Tree). I am trying to use an AP to SM link as the backup link for my management/monitoring purposes. The simplified flow is in the attached drawing (testing this in my office right now).
I am unable to get the AP/SM combo to pass the control traffic generated by the switch. There is a deciated control VLAN created, that carries only this control traffic between the switches, no IP traffic at all (just tagged out and in at each node). The master switch generates the packets with a source MAC 00-E0-2B-00-00-01 and a destination MAC 00-E0-2B-00-00-04.
With the primary port (control egress) connected to the 450i AP, I see the frames received on this control VLAN (in Statistics), but not transmitted, and do not see the source or desintation MAC listed in the Bridging Table.
With the secondary port (control ingress) connected to the 450i SM, I do not see any packets on the control VLAN, but I see the source MAC in the Bridging Table on Eth0.
I'm not sure why the radios don't pass this traffic properly. I have the VLANs configuraed correctly (I use VLANs a lot). I have been using this method for many years, currently over 10 other links that use PTP radios, without issue.
Thanks in advance.
