有些时候，我们可能会遇到IOS XE设备的high memory的情况。我们可以使用的命令去查看相关信息。
例如：
Router# show version
Router# show memory
Router# show processes memory
Router# show platform software status control-processor brief
Router# show platform resources
Router# show processes memory platform sorted
接下来，对上述命令进行解释。
show ver不用说明了，查看设备的软件版本，运行时间、physical memory、flash memory等情况。
1、show memory
Cisco IOS守护进程中的系统内存使用情况。
Cisco IOSd runs as its own process and it allocates memory from the system. It uses its own memory manager for features running within Cisco IOSd. In general, Cisco IOSd is allowed to use a maximum of approximately ? of the total system memory. However, it uses less system memory depending on the configuration. IOS will consume （消耗） system memory as needed to satisfy memory requests for features within Cisco IOSd. To do this, it uses a feature referred to as Cisco IOSd Dynamic Heap (dHeap). With dHeap, Cisoc IOS will request memory from the operating system based on demand as indicated by the dHeap output indicated in the show memory command.
要查找Cisco IOSd正在使用的系统内存总量，请使用Cisco IOS XE系统内存命令。
Router# show memory
