How To

too small flash to upload a new software

In my previous post I wrote about upgrade of Huawei S5300 switch. The question is, what to do if flash memory is too small to fit more than one software. As it was mentioned last time, you can format flash from bootrom menu and download a new software using FTP, from bootrom menu. In this post I will show you how to deal with this problem more smoothly. You can come up against this problem in Huawei S3328TP-SI switch, where flash capacity is 15MB. Let’s take it as an example.

<S3328>display version
Huawei Versatile Routing Platform Software
VRP (R) Software, Version 5.30 (S3328 V100R003C00SPC301)
Copyright (C) 2008-2009 Huawei Technologies Co., Ltd.
Quidway S3328TP-SI uptime is 0 day, 0 hour, 4 minutes

As you can see flash capacity is 15MB:

<S3328>dir
