Hi,


Do S-Series switches have 25GE speed ports?


If so, which models support SFP28?


Thank you.

Hi,

Indicators on the CE6865-48S8CQ-EI are the same as those on the CE6860-48S8CQ-EI. The CE6860-48S8CQ-EI is used as an example here to describe the indicators.

Ports

10GE/25GE SFP28 Optical Port

10GE/25GE SFP28 optical ports cannot work at 100 Mbit/s. Table 2-190 describes attributes of a 10GE/25GE SFP28 optical port.
Table 2-190 Attributes of a 10GE/25GE SFP28 optical port

Specification

Connector type

Depending on the optical module

Optical attributes

Depending on the module or cable in use

Port use constraints

The 48 10GE/25GE SFP28 optical ports of a CE6865EI switch 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 48 10GE/25GE SFP28 optical ports are divided into 12 port groups, with four ports in each group (1-4, 5-8, 9-12...45-48).
  • 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 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.
