The trap-door mechanism provides enough access to the system so that if it is necessary, you can format the flash file system, reinstall the operating system software image by using the Xmodem Protocol, recover from a lost or forgotten password, and finally restart the operating system. The boot loader also provides trap-door access into the system if the operating system has problems serious enough that it cannot be used. After the boot loader gives the operating system control of the CPU, the boot loader is not active until the next system reset or power-on. Normally, the boot loader is used only to load, uncompress, and launch the operating system. The boot loader provides access to the flash file system before the operating system is loaded.

Loads a default operating system software image into memory and boots up the switch.

It tests the CPU DRAM and the portion of the flash device that makes up the flash file system.

Performs power-on self-test (POST) for the CPU subsystem.

It initializes the CPU registers, which control where physical memory is mapped, its quantity, its speed, and so forth.

Performs low-level CPU initialization.

The normal boot process involves the operation of the boot loader software, which performs these activities: To start your switch, you need to follow the procedures in the Getting Started Guide or the hardware installation guide for installing and powering on the switch and for setting up the initial switch configuration (IP address, subnet mask, default gateway, secret and Telnet passwords, and so forth). For complete syntax and usage information for the commands used in this chapter, see the command reference for this release and the Cisco IOS IP Command Reference, Volume 1 of 3: Addressing and Services from page.

I really want to have VLAN2 up with the new address, and I don't really care about the VLAN1 interface anymore. When I do 'show interfaces', it shows interface VLAN1 is up, line protocol is up (but with no IP address) and it shows interface VLAN2 is deleted, line protocol is down. So - now, when I do 'show config', it still shows interface VLAN1 there with 'no ip address', and interface VLAN2 isn't there at all. This address is incorrect - it should actually be an address in 192.168.4.x, and it should be assigned to VLAN2. The switch is configured with 3 VLANs, and VLAN1 has an ip address assigned to it 192.168.2.100. I'm looking for some guidance on configuring VLANs and assigning addresses to them.I'm using a Catalyst 2950, with IOS version 12.0 (a little old, I know.)
