Handling Process

  1. Check Tecal server product documentation. See that management port support only 100Mb rate.
    2. Check S9703 line card.
    It is EH1D2X40SFC0, has  forty 10GE BASE-X optical ports.
    3. From dis transceiver command we see, that  1000_BASE_T_SFP is used.
    4. Tried to use command speed 100 at XGE interface of S9703 switch. No such command at interface.

    [DC-Core-XGigabitEthernet1/0/6]  undo negotiation auto
    Speed 100
    Error: Unrecognized command found at ‘^’ position.

    5. Check S9703 documentation about speed command. See NOTE.

Root Cause

When an XGE interface has a GE copper module installed, the rate of the interface can only be negotiated to 1000 Mbit/s.
