Table 5-30 describes functions and features of the CE88-D24S2CQ-U card.

Table 5-30 Functions and features

Function and Feature	Description
Basic function	Provides data packet processing and traffic management on 24 25GE/10GE SFP28 optical ports and two 40GE/100GE QSFP28 optical ports. The 24 25GE/10GE SFP28 optical ports can be configured as 24 FC interfaces (supporting rates of 4 Gbit/s, 8 Gbit/s, and 16 Gbit/s).
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.
Hot swap	Supported
Service port stacking	Ports on the card can be used as stack ports. NOTE: 24 25GE/16G FC optical ports cannot be used for stack connections.

25GE/16G FC (SFP28) optical port

25GE/16G FC (SFP28) optical ports cannot work at 100 Mbit/s. Table 5-32 describes attributes of a 25GE/16G FC (SFP28) optical port.

Table 5-32 Attributes of a 25GE/16G FC (SFP28) optical port

Attribute	Description
Connector type	Depending on the optical module used.
Optical attributes	Depending on the optical module used.
Port use constraints	The 24 25GE/16G FC (SFP28) optical ports of the CE88-D24S2CQ-U work at 25 Gbit/s by default and do not support GE/10GE auto-sensing. You can set the port speed to 10 Gbit/s or 1 Gbit/s using the port mode 10g or port mode ge command. The 24 25GE/16G FC (SFP28) optical ports are divided into six port groups, each of which contains four ports (1-4, 5-8, 9-12...21-24). If the speed of any port in a port group is set to 1 Gbit/s, 10G bit/s, or 25G bit/s, all the other ports in this group also work at 1 Gbit/s, 10G bit/s, or 25G bit/s. When the ports in a port group work at 25 Gbit/s, they support only 25GE modules or cables and will go Down if other types of modules or cables are used. When the ports in a port group work at 10 Gbit/s, they support only 10GE or 25GE variable-rate modules or cables and will go Down if other types of modules or cables are used. When the ports in a port group work at 1 Gbit/s, they support only GE modules or cables and will go Down if other types of modules or cables are used. The maximum rate supported by a 16GE FC optical port is 14 Gbit/s. A 25GE optical interface does not support auto-negotiation when it has a GE optical module installed. To connect the two interfaces at both ends of a link, disable auto-negotiation on the peer interface. Otherwise, one interface may go Up and the other may go Down.
Applicable cables	When the port works in 10GE mode, it can use: 10GE optical module (OSXD22N00, LE2MXSC80FF0 and SFP-10G-ZDWT-L not supported) GE cooper module (supported from V200R005C100 version and only works at 1000 Mbit/s) GE optical module (supported from V200R005C100 version) SFP+ to SFP+ high-speed cable SFP+ to SFP+ AOC cable
	When the port works in 25GE mode, it can use: SFP-25G-SR optical module SFP28 to SFP28 AOC cable SFP28 to SFP28 high-speed cable (1m, 3m, or 5m)
	When the port is configured as an FC port, it can use: 4G/8G/16G SFP optical module and LC optical fiber

40GE/100GE QSFP28 optical port

Table 5-33 describes the attributes of a 40GE/100GE QSFP28 optical port.

Table 5-33 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
