Hello all,

We have a CE6865-48S8CQ-EI. After replacing a 25G SPF with a 10G SPF, the interface cannot go up.

The 10G SPF is taken from other devices.  What could be the reason? 

Thank you.

Hello Sprout,

The 48 10GE/25GE SFP28 optical ports on the CE6865EI switch are divided into 12 port groups. Each port group (1-4, 5-8, 9-12...45-48) contains four ports. 

When the rate of any port in a port group is set to 1 Gbit/s, 10 Gbit/s, or 25 Gbit/s, the rates of all the other ports in the port group are also set to 1 Gbit/s, 10 Gbit/s, or 25 Gbit/s. 

When a port group works at the rate of 25 Gbit/s, it supports only 25GE modules or cables. Otherwise, the interface goes Down. ( Same for the 1GE or 10GE port group)

Therefore, you need to change the port rate after you insert the 10GE SFP to the 25GE port.

The command is port mode 10g

Hi User,
The 48 10GE/25GE SFP28 optical ports of a CE6865EI switch work at the rate of 25 Gbit/s by default and do not support GE/10GE auto-sensing. You can set the port rate to 10 Gbit/s or 1 Gbit/s using the port mode 10g or port mode ge command, respectively.

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 rate of any port in a port group is set to 1 Gbit/s, 10 Gbit/s, or 25 Gbit/s, all the other ports in this group also work at the rate of 1 Gbit/s, 10 Gbit/s, or 25 Gbit/s.

When the ports in a port group work at the rate of 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 the rate of 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 the rate of 1 Gbit/s, they support only GE modules or cables and will go Down if other types of modules or cables are used.
