Why does " l2protocol peer stp" show up as an option if it's not supported? Is
that one of those things with ios that commands are there but don't work type of thing?
...anyway, is MST (802.1s) supported on efp's?

If the 4500 is one of your core devices then just configure the port as
a normal switchport trunk.
IMHO EFP's are more suited and designed to be used on customer facing
ports (PE->CE) rather than core facing uplinks (P-PE).
Aside from that, the restriction about only being able to peer with MSTP
across EFP's is a pretty horrendous one, I was really surprised to find
that even Cisco's Rapid PVST isn't supported and it's not on the roadmap :-(
