I have 3 sites that are connected by radio equipment (radio's are Layer 1 device), the Switch ports are "Fiber" and configured as Trunk and native Vlan 200, PVST and UDLD aggressive are enable on uplinks
The radio's have a management interface (copper) and are connected to the same switch as the fiber at each site, with the copper port set as access Vlan 400. All routing is done in the main building (site 1) on the core switch.
The problem is I can't access the management on the radio's across the radio link (site 2 and site 3). What I'm seeing is MAC address for the management interface is being seen on both the copper interface Vlan 400 and the fiber link Vlan 200. The radio's are running an embedded Linux OS and we don't have the ability to alter the default behavior of the Linux system to arp on both interfaces.
I've tried blocking the MAC address from Vlan 200, that stop's the core switch from learning it on the wrong Vlan bit we still cant get to the radio management (I think even though the MAC is being blocked the switch is still trying to use the fiber interface as the destination).
Is there a way force the switch to use the copper interface as the source?
