问题描述

S5732-H24UM2CC配置MultiGE口频点模式为2.5G报错:

[S5732-MultiGE0/0/1]port serdes-mode 2500-base-x xfi

   Warning: Some interfaces may fail to go UP after this command is run. Continue? [Y/N]:y
   Error: The configuration conflicts with the serders configuration on interfaces MultiGE0/0/1 to MultiGE0/0/8.

无

处理过程

1、该功能需要license是支持，查看是否有对应license：

  <S5732> display license

  Active license : flash:/lic****379.dat

  License state : Normal
  Revoke ticket : No ticket
 
  No relevant customer information

  Product name : S5700
  Product version : all
  License Serial No : LIC2020******V60
  Creator : Huawei Technologies Co., Ltd.
  Created Time : 2020-12-11 22:02:43
  Feature name : S5732-H
  Authorize type : COMM
  Expired date : PERMANENT
  Trial days : --

  Item name Item type Value Description
  -------------------------------------------------------------
  L-1GUPG10G-S57H Resource 2 MultiGE port speed from 1GE to 10GE  //有对应功能的license

 2、查看MultiGE接口组的接口速率信息。
  <S5732> display device group-speed configuration                              
                                                                                        
  -------------------------------------------------------------------------------                                                     
  Slot Group  Interfaces            BaseSpeed ConfigSpeed CurrentSpeed NextSpeed                                                      
  -------------------------------------------------------------------------------                                                     
  0    0    MultiGE0/0/1  ~ 0/0/12   1G        1G         1G          1G            

  CurrentSpeed为设备本次启动时MultiGE接口组的接口支持的最大速率，当前为1G。需要修改最大速率满足大于等于2.5G才行。      

根因

设备MultiGE接口组当前最大速率是1G，不能配置比1G大的速率，所以配置2.5G的时候会报错

解决方案

  配置上assign group-speed为2.5G，再配置频点为2.5G。举例：

  [S5732] assign group-speed group 0 2500   

  [S5732] interface MultiGE 0/0/1

  [S5732-MultiGE0/0/1]port serdes-mode 2500-base-x xfi 

  配置完成后重启设备。
