关于 Nexus 5596 在interface vlan 下不能对ACL进行删除

如题,请教大家,下面红字报错是什么原因导致?这个组策略port_445  下面是一个空的列表。有些贴子里说,需要重启交换机可以解决这个问题,但是这台交换机是用户的核心设备,客户不太愿意重启,没有嘛好的解决方式?

ERROR: no free label Message for ACL modification
CSCus09017
 
Description
Symptom:
The Next message is output when the Customer tries to modify an ACL applied in the SVI (delete, modify, enable): ACLMGR-3-ACLMGR_VERIFY_FAIL: Verify failed: no free label

N5K(config)# int vlan 527
N5K(config-if)# no ip access-group NAME in
ERROR: no free label
N5K(config-if)#

No Hardware limits are crossed

Conditions:
Apparently the TCAM label is being used by two different features (RACL, and PBR). This is causing the label allocation error.

Workaround:
Identify the duplicated labels between PBRs and ACLs, remove the configuration for the PBRs, save configuration, reload the Switch, and the apply the PBR configuration back. For more Information Contact TAC

Further Problem Description:
应该是和这个bug有关系,Workaround也是这么说,所以如果有所顾虑的话,建议开TAC CASE。
