3550 Flash Files

I just got a used 3550 and see a number of files in flash:

Directory of flash:/

2 -rwx 322 Mar 1 1993 00:02:24 +00:00 system_env_vars 3 -rwx 3721 Mar 1 1993 00:06:22 +00:00 config.text 4 -rwx 187 Mar 12 1993 02:38:15 +00:00 layout.text 5 drwx 0 Mar 1 1993 02:10:37 +00:00 lost+found 6 -rwx 121 Mar 12 1993 00:29:11 +00:00 layoutOption.txt 8 -rwx 0 Mar 1 1993 00:02:24 +00:00 env_vars 7 -rwx 24 Mar 1 1993 00:06:22 +00:00 private-config.text 24 -rwx 7134015 Mar 1 1993 00:15:51 +00:00 c3550-ipservicesk9-mz.122-25.SEE2.bin

What are layout.text and layoutOption.txt?

3550#more layout.text CISCOKID001;__network_root_node__,-1000,-1000,true;0009.b7e1.3100,59,18,false;ecs44h2,-1000,-1000,true;0009.b7e1.f800,379,27,false;0009.e811.7400,223,25,false;0009.b79c.9f80,221,216,false

3550#more layoutOption.txt IPPhone:true,HName:true,LinkSpeed:true,IPAddr:true,AP:true,CPE:true,Candidate:true,IName:true,Neighbor:true,MACAddr:false

Why are there two entries with zero bytes: the lost+found directory and env_vars?

What is private-config.text and why can I not display the contents?

3550#more private-config.text %Error opening flash:/private-config.text (Permission denied)

IIRC, something from the web based switch manager that must have been deleted off your flash at a later time. The old one was pretty bad. The newer one is passable, but I think thats only available in switches newer than that model.

In Unix (which clearly has influenced IOS in many ways), lost+found is the directory on the file system where recovered/damaged & recovered files are placed after a fsck. Probably never used on Cisco.

env_vars hold variables between reboots. I believe the function of this has changed over the years, and is no longer needed, but is still there.

Private data to the switch that Cisco doesn't want you to see. I suspect there could be some licensing there for some models..

I don't care about browser-based management so I'd like to delete the layout files. Can you think of any reason not to erase them and the zero byte file and directory as well?

Or to put it another way, does the switch need anything besides an image file (and maybe system_env_vars) to run?

I would think the layout files are totally fine to wipe.

I wouldn't try to remove the other files that are always there. There could be some boot code detection looking for those, even if they aren't used.

Err, why? Its not like there's alot of stuff happening there anyway.
