This is a set of instructions that someone had posted to install CallManager on hardware other than their “certified” equipment for testing.

Step 1: Download a Windows utility called FDIMAGE.EXE. You can find this on pretty much any UNIX/ Linux site.

Step 2: Insert the CallManager Hardware Detect CD-ROM into the system

Step 3: Insert a blank floppy disk

Step 4: Open up a DOS window and type fdimage d:\bootimg.bin a:. This will copy the boot image from the Hardware detect CD-ROM to the floppy.

Step 5: On the floppy, edit the autoexec.bat file and change the following:
locate sssksys.ini
add:set XIMAGE=x345
goto IBMx345

Step 6: Reboot and make sure the a: is setup as yoru boot drive. Also ensure the CD is still in there.

Step 7: Everything after this is business as usual.

Here’s a few commands that are helpful if you are configuring numerous ports for hosts.

spanning-tree portfast default

This command automatically sets any port configured as an access port (non-trunking) to the correct mode.

switchport host
switchport mode will be set to access
spanning-tree portfast will be enabled
channel group will be disabled

Found this handy command within Cisco docs. It especially comes in handy on bloated 6500’s, however, it doesn’t matter if you don’t put descriptions on your interfaces and vlan’s.

show interface description
or
sh int desc
