7520 switch running vsp fails to connect to BT NTE

calendar_today October 5, 2026 person ShaunM domain extreme-networks

We have been running a migration successfully until we hit a snag recently. I have a 7520 switch running VOSS 9.4.1 with a 1gig SX SFP installed. We move a working BT NTE connection at 1gig from the Cisco to the Extreme (same SFP type and same cable) and the Extreme switch brings the interface up/up, however the NTE is orange indicating an error on its side.
