I am planning to connect an existing Cisco 3750 switch to a 3560C switch over a wireless PTP bridge. The bridge will be WPA2 protected, but I am looking for an additional measure of security between the switches to prevent other wireless access through either switch.

They do not support IPSec, only 802.1Q tunnels, and buying additional hardware is not likely an option.

I am looking into using TrustSec manual mode between the switches. After some effort reading into TrustSec and MACsec, I am mostly certain this is a good choice over the wireless bridge, keeping in mind it is a shared medium.

Two questions:

Can I reliably prevent other wireless traffic from accessing the switches using TrustSec?
Does anyone know of any better options with the 3000 series switches?
