某局点 S6520X-EI 修改flow-interval未生效问题

S6520X-EI R6326版本 

某局点修改接口下flow-interval采样时间为5s但是display interface看仍为300s

interface Ten-GigabitEthernet1/0/8

port link-mode bridge

port link-type trunk

port trunk permit vlan 1 91 888 to 896 901 to 905 911 to 918 930 to 931 940 to 941 943 to 948

flow-interval 5

port link-aggregation group 8

怀疑是显示错误，但新版本说明书中没有相关已知问题。

经确认，R6329之前的版本端口下配置flow-interval后实际已经生效，但是display interface 显示的Last 300 seconds 显示错误，错误地按照flow-interval全局配置的时间（300s）显示，现场可升级至R6329版本解决。
