某局点S12508-AC日志告警资源不足“No enough resource!”经验案例

无。

客户现场反馈交换机大量的日志提示资源不足的报错，但是没有看到mac、acl、route等规格超标，报错信息如下：

%Nov  5 10:53:07:856 2018 12508-C DRVL3/3/DRVL3_LOG_ERR: -Slot=3; No enough resource!

%Nov  5 10:53:07:973 2018 12508-C DRVL3/3/DRVL3_LOG_ERR: -Slot=4; No enough resource!

%Nov  5 10:53:07:974 2018 12508-C DRVL3/3/DRVL3_LOG_ERR: -Slot=4; No enough resource!

1、 查看设备的mac、route表项：

2、搜集display qos-acl resource资源也是使用率为0，说明也不是acl资源导致的。

3、但是从诊断里面看出设备组播表项不多了，并且三层转发资源也是不足：

  ===============Display l3mc keyinfo slot 3===============

===============================================================

TCAM Resource: total 511 free 511

通过display device verbose看到现场使用的接口单板为LST1XP8LEB1的EB类单板。 查询官网资料显示EB单板不能修改系统工作模式，因此资源不足建议用户切换部分流量到其他设备上去转发。
