  Table 2-1 Common attributes of Ethernet interfaces

  Interface Type	Common Attributes	Remarks
  FE electrical interfaces	Transmission medium: network cable Rate: 10 Mbit/s and 100 Mbit/s Duplex mode: full-duplex/half-duplex Auto-negotiation: supported Flow control: supported Flow control auto-negotiation: supported Received flow control: supported Received flow control auto-negotiation: supported	-
  GE electrical interfaces	Transmission medium: network cable Rate: 10 Mbit/s, 100 Mbit/s, and 1000 Mbit/s Duplex mode: full-duplex/half-duplex. When the rate is 1000 Mbit/s, only full-duplex is supported. Auto-negotiation: supported Flow control: supported Flow control auto-negotiation: supported Received flow control: supported Received flow control auto-negotiation: supported	The duplex mode cannot be configured for interfaces on the X1E series cards working in either auto-negotiation or non-auto-negotiation mode.
  FE optical interfaces	Transmission medium: FE optical module Rate: 100 Mbit/s Duplex mode: full-duplex Auto-negotiation: not supported Flow control: supported Flow control auto-negotiation: not supported Received flow control: supported Received flow control auto-negotiation: not supported	-

Auto-negotiation: supported Flow control: supported Flow control auto-negotiation: supported Received flow control: supported Received flow control auto-negotiation: supported	By default, auto-negotiation is enabled on GE optical interfaces and rate auto-negotiation is disabled. You can run the speed auto-negotiation command to enable rate auto-negotiation. After a copper module is installed on a GE optical interface of an X2E/X2S/X6E/X6S series card, the interface can work at the rate of 100 Mbit/s or 1000 Mbit/s (including forcible configuration and auto-sensing), and cannot work at the rate of 10 Mbit/s. When the interface works as an optical interface, it can only work at the rate of 1000 Mbit/s, and cannot work at the rate of 100 Mbit/s.

The cards include: SC series cards ES1D2X16SFC00, ES1D2X40SFC0, ES1D2X40SFC0, ES1D2X16SFC00, EH1D2X16SFC0, and EH1D2X40SFC0 cards in the FC series EH1D2X48SEC0 and ET1D2X48SEC0 cards in the EC series Assume that an XGE optical interface has an XGE/GE optical module installed and the interface rate is set to 1000 Mbit/s using the speed auto 1000 command. When you run the display interface command on the interface, the command output shows that auto-negotiation is enabled. However, you cannot run the negotiation auto command to configure the auto-negotiation mode. On the S7700, the interfaces on the ES0D0X12SA00, ES0D0X12SA01, and ES1D2X08SED4 cards, and XGE optical interfaces on the ES1D2S04SX1E and ES1D2S08SX1E cards do not support GE copper modules. On the S9700, the interfaces on the EH1D2X12SSA0, ET1D2X12SSA0 and EH1D2X08SED4 cards, and XGE optical interfaces on the EH1D2S04SX1E, ET1D2S04SX1E, ET1D2S08SX1E and EH1D2S08SX1E cards do not support GE copper modules. After a GE copper module is installed on an XGE interface of an X2E/X2H/X2S/X6E/X6S series card, the interface can work at the rate of 100 Mbit/s or 1000 Mbit/s, and cannot work at the rate of 10 Mbit/s. After a 1000M optical module is installed on an XGE interface of an X2E/X2H/X2S/X6E/X6S series card, the interface can work at the rate of 1000 Mbit/s.

After a 40GE optical module or 40GE high-speed cable is installed on a 100GE interface of an X2E/X2H/X2S series card, the interface can work at the rate of 40 Gbit/s. After a 40GE optical module is installed on a 100GE interface of an X6E/X6S series card, the interface can work at the rate of 40 Gbit/s. When you need to install high-speed cables on 100GE interfaces of X6E/X6S series LPUs, only QSFP28 high-speed cables of 1 or 3 meters can be used (can only be used as a CSS cable in ports 0 to 5).
