无。

问题描述

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macaclroute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!

%Nov  5 10:53:07:974 2018 12508-C DRVL3/3/DRVL3_LOG_ERR: -Slot=7; No enough resource!

%Nov  5 10:53:07:974 2018 12508-C DRVL3/3/DRVL3_LOG_ERR: -Slot=7; No enough resource!

%Nov  5 10:53:07:977 2018 12508-C DRVL3/3/DRVL3_LOG_ERR: -Slot=3; No enough resource!

过程分析

1、 查看设备的macroute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===============

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

Resource Info:

TCAM Resource: total 511 free 511

Local DIT Resource: total 780 free 6 usage list:

  L3MC: 774

 

  ===============Display l3mc keyinfo slot 4===============

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

Resource Info:

TCAM Resource: total 511 free 511

Local DIT Resource: total 780 free 6 usage list:

 

  ===============Display l3mc keyinfo slot 7===============

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。


解决方法

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 。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之后解决资源不足的告警问题。
