存储器容量以及所支持的系统文件
下面列出了交换机的存储器容量以及所支持的系统文件
旧版本 Catalyst 2900系列 XL 交换机(2 MB Flash,4MB DRAM)
升级这些交换机到下列之一: original Catalyst 2900 Series XL Cisco IOS Software Release 11.2.8SA6 software, 或者 earlier Catalyst 2900 Series XL original software
计数忽略: 由于源交换机链路中能量消耗引起的帧数量计数丢失 The Ignored Counter: Counts the number of frames dropped on input due to resource exhaustion in the switch fabric. 溢出: 当内部帧间断太短时发生。在这种情况中,当先发送的帧还没有被内存完全存储前,一个新的以太网帧就已经到达。

Once the switch IOS is fully loaded, you can use the show post command. This command, available beginning with Cisco IOS Software Release 11.2(8.5)SA6, checks if the POST tests passed. If there is a failure, it determines which POST test failed. Upon reloading the switch, you can also monitor the post tests as they are running via a console connection to the switch.
