Description
This article describes the recommended Port speed configuration for SR (short range) SFP cable.

Solution
By default, the speed config set on SFP port is auto-module:
# config switch physical-port
    edit "port52"
        set speed auto-module
    next
end
While using SR cable for example: 10gbps, consider changing the speed to 10000sr.
# config switch physical-port
    edit port52
        set speed 10000sr
end
Reason.
It is recommended to change the speed configuration for SR cable to avoid CRC alignment errors and Rx errors/discards.
