Switch Model	CE88-D8CQ
CE7800, CE6800, and CE5800 series switches and the CE8850EI	Not supported
CE8860-4C-EI	Supported in V100R006C00 and later versions
CE8861-4C-EI CE8868-4C-EI	Supported in V200R005C10 and later versions NOTE: The registration and interface usage of the CE88-D8CQ subcards on the CE8868EI are controlled by licenses. By default, the CE88-D8CQ subcards on the CE8868EI are not enabled. To use these subcards on the CE8868EI, apply for and purchase the license from the equipment supplier. For the CE8868EI, after the above license is loaded, you need to run the active card-license command to enable the corresponding license in the specified subcard slot. The CE8868EI has four subcard slots. You can purchase licenses based on the number of required subcard slots.

Functions and Features

Table 5-4 describes functions and features of the CE88-D8CQ card.

Table 5-4 Functions and features

Function and Feature	Item
Basic function	Provides data packet processing and traffic management on eight 40GE/100GE QSFP28 optical ports.
Port split	Each QSFP28 optical port can be split into four 25GE ports or four 10GE ports. Such 25GE or 10GE ports cannot work at 1 Gbit/s. With the port split function, each card can provide up to 32 25GE or 10GE optical ports. NOTE: All the QSFP28 ports are independent, and each can be configured as four 10GE or 25GE ports.
Hot swap	Supported
Service port stacking	Ports on the card can be used as stack ports.

Indicators and Ports

Table 5-5 describes indicators on the CE88-D8CQ panel.

Table 5-5 Indicator description

Number	Indicator	Color	Status	Description
1	One single-color indicator for each interface NOTE: Arrowheads show the positions of ports. A down arrowhead indicates a port at the bottom, and an up arrowhead indicates a port at the top.	Green	Off	No link is established on the port.
			Steady on	A link has been established on the port.
			Blinking	The port is transmitting or receiving data.

Table 5-6 describes the attributes of a 40GE/100GE QSFP28 optical port.

Table 5-6 Attributes of a 40GE/100GE QSFP28 optical port

Attribute	Description
Connector type	Depends on the optical module used.
Optical attributes	Depends on the QSFP+ or QSFP28 optical module used. See 40GE QSFP+ Optical Modules or 100GE QSFP28 Optical Modules.
Applicable cables	When the port works in 100GE mode, it can use: QSFP28 optical module and MPO-MPO or LC-LC optical fiber (QSFP28-100G-4WDM-40 not supported) QSFP28 to QSFP28 high-speed cable QSFP28 to QSFP28 AOC cable
	When the port works in 40GE mode, it can use: QSFP+ optical module and MPO-MPO or LC-LC optical fiber QSFP+ to QSFP+ high-speed cable QSFP+ to QSFP+ AOC cable
	When the port works in 425GE mode, it can use: QSFP28 optical module and MPO-4DLC or MPO-8FC optical fiber (QSFP28-100G-4WDM-40 not supported) QSFP28 to 4SFP28 high-speed cable NOTE: When a QSFP28-100G-SR4 optical module is installed on the port, the port cannot be connected to a port with an SFP-25G-SR optical module. When a QSFP28 to 4*SFP28 high-speed cable is installed on the port: If auto-negotiation is disabled on the remote port, the local port supports only the QSFP-4SFP25G-CU1M or QSFP-4SFP25G-CU3M-N high-speed cable. If auto-negotiation is disabled and Base-R FEC is enabled on the remote port, the local port supports only the QSFP-4SFP25G-CU3M high-speed cable.
	When the port works in 410GE mode, it can use: QSFP+ optical module and MPO-4DLC or MPO-8FC optical fiber QSFP+ to 4SFP+ high-speed cable QSFP+ to 4*SFP+ AOC cable
