内存分配错误，太多分配碎片，无法分配到内存。
建议处理方法：重启一下看看是否恢复正常；记录两次出问题的时间间隔；考虑升级交换机软件。
没有谁能像一座孤岛/在大海里独踞/每个人都像一块小小的泥土/连接成整个陆地/如果一块泥土被海水冲去/欧洲将缺其一隅/这如同一座山岬/也如同你的朋友和你自己/无论谁死了/都是自己的一部分在死去/因为我包含在人类这个概念里/因此我从不问丧钟为谁而鸣/它为我，也为你
No man is an Island, entire of itself; every man is a piece of the Continent, a part of the main; if a clod be washed away by the sea, Europe is the less, as well as if a promontory were, as well as if a man or of thy friends or of thine own were; any man's death diminishes me, because I am involved in Mankind; And therefore never send to know for whom the bell tolls; It tolls for thee.

谢谢麦子回复,正好将此交换机导致的奇怪故障说一说,看看是不是由这个内存问题引起的
网络结构情况:
1.此3550是楼层接入交换机
2.核心交换是6509和4006互备
3.3550的Gi0/1(trunk)接入6509, fa0/48(trunk)接入4006
故障现象:
网络运行一直比较稳定,昨天中午网络突然阻塞,4006已经无法telnet,
telnet到6509上,sh proc cpu sort,发现资源占用达到95%左右,
其中ospf hello达到30%,ip input达到18%
检查:
怀疑蠕虫病毒攻击,广播包攻击或ARP欺骗
1.使用CONSOLE登陆4006,
sh cam dynamic
sh ip arp
没有发现大量伪造IP和MAC迹象
执行debug ip packet
发现有大量组播包,源IP是6509
2.telnet 6509
sh mac-
sh ip arp
没有发现大量伪造IP和MAC迹象
执行debug ip packet
发现有大量组播包,源IP是127.0.0.3
3.检查6509和4006上spanning-tree,均正常
4.无意间关掉4006,网络正常
处理:
逐个断开4006上的接入交换机trunk线
发现
将fa0/48(trunk)线路断开,网络正常
重新接上此trunk,网络又阻塞
telnet到3550,
sh logging即出现内存错误 |

能不能查询到127.0.0.3是从哪里来的? |
