某局点SR8808-X配置CBQ时提示资源不足

某局点客户反馈SR8808-X版本是Release 7655P10，配置CBQ带宽保证时提示资源不足导致下发失败，完整故障信息如下

[HB2-R1-Pos0/4/1]qos apply  policy  vpn-policy outbound

第二步 查看设备acl资源信息

nterfaces: GE2/1/1 to GE2/1/8, Pos2/4/1 to Pos2/4/4 (slot 2)

---------------------------------------------------------------------

Type             Total      Reserved   Configured Remaining  Usage

---------------------------------------------------------------------

VFP ACL          2048       512        0          1536       25%

IFP ACL          8192       3072       3          5117       37%

IFP Meter        4096       1536       1          2559       37%

IFP Counter      4096       1536       2          2558       37%

EFP ACL          1024       0          0          1024       0%

EFP Meter        512        0          0          512        0%

EFP Counter      512        0          0          512        0%

第三步查看硬件板卡信息如下

===============display device verbose=============== 

Slot No. Brd Type         Brd Status   Software Version

 0       MPE-1104         Normal       SR8800-CMW710-R7655P10

   Sub1  MIC-GP8L         Normal   

   Sub2  MIC-CLP2L        Normal   

   Sub3  NONE             Absent   

   Sub4  MIC-SP4L         Normal 

经确认由于MPE-1104单板限制，一个接口只能配置一个EF队列，而客户配置了三个EF队列导致资源不足 

修改配置为一个EF队列组问题解决。
