10Gb SFP+ Autonegotiation

I'm having trouble getting autonegotiation status on a 10Gb SFP+ port on a QFX5100. Whether autonegotiation is set or not I don't see anything that indicates if autoneg is on, or what the outcome was.

1Gb-T, I see status, partner, and local:

Physical interface: ge-0/0/0, Enabled, Physical link is Up
  Interface index: 659, SNMP ifIndex: 558, Generation: 150
  Link-level type: Ethernet, MTU: 1514, MRU: 0, Speed: 1000 Mbps, Duplex: Auto,
  Autonegotiation information:
    Negotiation status: Complete
    Link partner:
        Link mode: Full-duplex, Flow control: Symmetric, Remote fault: OK,
        Link partner Speed: 1000 Mbps
    Local resolution:
        Flow control: None, Flow control tx: None, Flow control rx: None,
        Remote fault: Link OK

10Gb-SR, Nothing:

Physical interface: xe-0/0/28, Enabled, Physical link is Up
  Interface index: 686, SNMP ifIndex: 548, Generation: 179
  Link-level type: Ethernet, MTU: 1514, MRU: 0, Speed: 10Gbps, BPDU Error: None, MAC-REWRITE Error: None,
  Loopback: Disabled, Source filtering: Disabled, Flow control: Disabled, Media type: Fiber

}

        vlan {
            members [ 160-162 260 666 680 780 999 ];
        }
    }
}

Is this info somewhere else?
