Could be the config file type. &nbsp;Whether it is a backup file or config file. &nbsp;In general you select the file to use for the next boot with the following command:<br />
startup saved-configuration filename [ backup | main ]<br />
where filename is the config file name and backup or main denotes whether it is a backup file or main config file. &nbsp;Either type can be used as the startup config file

thanks for the quick reply ,,,<br />
i tried this command before as noted in my question ,, either way the main and backup denotes does not exist.<br />
hope there is any other way.<br />

hi all fellow experts,,<br />
i have a problem in 3com 4500 that does not load the configuration file .. and it is loading with the default configuration ,, <br />
i tried to configure it and save the configs and it does save successfully but when i reboot the switch it goes back to the Default config.<br />
the most noticable thing is that <br />
Startup save configuration file = null<br />
next Startup save configuration file = flash:/config.cfg<br />
and when i set the null to flash:/config.cfg it saves and when i reboot it goes back to null with the default config loaded.<br />

3com 4500 switch has startup cfg file = null?

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
