我的网络健康吗?重要的CLI信息-(内存问题)

当你登录到路由器/交换机时，还有什么是重要的?我们谈到了' show version '命令，有更重要的东西要检查。例如内存。通过右键单击任务栏并选择任务管理器，可以监视内存使用情况。开玩笑的，你可以通过运行“显示内存”命令来查看内存信息。这将生成所有内存地址空间的列表，以及分配给什么。这不是最友好的命令，但我们主要对它生成的前几行感兴趣。输出被划分为处理器和IO，我们希望它们都不会被过度利用。你怎么知道你是否被过度利用了呢?设备将显示以下症状之一:*控制台或日志消息:"%SYS-2-MALLOCFAIL:…" *无论您在控制台上键入什么命令，都会显示显示处理器内存命令。 * No output from some show commands. * "Low on memory" messages. * The console message "Unable to create EXEC - no memory or too many processes". * Refused Telnet sessions. * Router hanging or no console response. Also the command ‘show memory failures alloc’ has some lines following it. There are things to do with memory issues, adding memory of course, but also try to put the latest recommended ios version to avoid memory leaks. If you want to see what process takes all the memory, execute the ‘show process memory sorted’ command. Normally on routers the number one consumer is the ip routing protocol (eigrp/bgp/ospf), if you see ARP or SNMP or other things that should not be using a lot of memory that might explain the problem. Here is a sample of it:这张图片在Geocities关闭时丢失了，如果需要请评论，我会试着复制更多信息请访问:http://www.cisco.com/en/US/products/sw/iosswrel/ps1831/products_tech_note09186a00800a6f3a.shtml。
