You need to copy the vlan.dat file or just recreate the vlans on the switch that you are moving to unless you are using VTP for vlan administration.

HI Nativevlan,

I dont know how to do that ,do you have a quick way to do so ,and maybe some reading ?

If it's a standalone switch in server or transparent mode, the VLAN's will be in the running-config.

If you're in a multi-switch environment and using VTP, the VLAN list will be pulled off a VTP server.
do a "dir nvram" to check the file name, it's possible to change the vlan.dat.

copy nvram:vlan.dat tftp

If it's just a few vlans it would be easier to recreate them.

HI all
the swith is a frount end to the internet for 24 different business ,ie keeping them from each other.

so from what you say the running-config should do the job if I read it right.
a.
It depends on the vtp mode yopu have right now.

If when you do a "show vtp status" you see "VTP Operating Mode: Transparent" or "client" then simply copying the running-config to the tftp server is all you need to do.

If you see the operating mode is "Server", then you'll also need to copy the vlan database.

"copy flash:vlan.dat tftp"

HI all,

OK I'LL give that AM  .

thank you for you help.

Another thing you can do it copy your config to a tftp server and move it that way, or just create a log file from a hyperterminal session, copy the text, and paste the config into the router.

HI all , users wont let us pull the switch for now, but I have one more queston , if you would like me to place another queston Iam happy to do so ...

any way -  the switch is in server mode  , so if I put the switch into mode mode will it effect the switch in that  could I lose the config , / will it ry and load from the server , witch is NO LONGER on site ?

First off, in VTP server mode, the config and the VLAN database are two separate things. Totally unrelated.

Second, if it's in server mode, do NOT change it to client mode! You can change it to transparent mode, but don't change it to client mode.

HI All,

so putting the switch into mode ,mode will not cause any problem and I can still copy off the
running-config & vlan by:-

copy running-config tftp

copy flash:vlan.dat tftp

reboot the switch and should be ok ?

Why are you going to reboot the switch?

And before you reboot or power down the switch, if you want it to still be functional in it's current location, you better issue a "copy run start" first.

Commented:
we need to backup the switchs  config on to a replacement unit

we don't have the current passwords , so we need to do a password recovery Via the power off/on mode  look at the running-config to get the enable password .

then enable & copy the configs off to the tftp server or if needed reset the passwords.

I am just conserned doing so with this switcg may lose the current config as its in server mode and the server is gone...

If you don't have the privileged mode password you will not be able to save, backup or view the current config. If the config has not been saved, it will be lost. But there is no other choice at this point.

Most likely, the config has been saved at some point so there will probably be some functionality after the password recovery is done.

How much (if any) of the config is lost, is the big unknown.

I am just conserned doing so with this switcg may lose the current config as its in server mode and the server is gone...

Once again, VTP server has NOTHING to do with the configuration of the switch. only the list of VLANs on the switch.

Hi All,
sorry about this but now I am lost...

will putting the cicso 2950 in to diag mode by powing off the switch / power on the switch while pressing the mode button lose the configs in this switch as it in    server mode ? see below

There is no way to know.

It is possible the configuration has been saved. But without getting into privileged mode,  you can't be certain.
