存儲器容量以及所支持的系統文件
下面列出了交換機的存儲器容量以及所支持的系統文件
舊版本 Catalyst 2900系列 XL 交換機(2 MB Flash,4MB DRAM)
升級這些交換機到下列之一: original Catalyst 2900 Series XL Cisco IOS Software Release 11.2.8SA6 software, 或者 earlier Catalyst 2900 Series XL original software
計數忽略: 由于源交換機鏈路中能量消耗引起的幀數量計數丟失 The Ignored Counter: Counts the number of frames dropped on input due to resource exhaustion in the switch fabric. 溢出: 當內部幀間斷太短時發生。在這種情況中,當先發送的幀還沒有被內存完全存儲前,一個新的以太網幀就已經到達。

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.
