pasting config to switch

DevilWAHDevilWAH Member Posts: 2,997 ■■■■■■■■□□
Hi,

When replacing a failed switch, my standard method for getting the config on to the new swich, is to console in and do a simple copy/past from a backed up file.

I find that this can cause an issue with large files, with lines getting missed.

do other people come across this and if so do they have any solutions for copying the config to a new switch?

I have used the xmodem protocol to copy the file across and this seems to work fine.

But I was wondering if there was a way to insue the copy past method does not miss lines?

Cheers

    have you tried slowing down the transmit rate? i.e. in tera term go to setup > serial port > then edit the transmit delay settings to determine the speed it will be transfered. This will then slow down your copy and paste.

    yer I did try this but even with it set to be 200msec per line it still has issues, and any slower than this, with a few hundrad lines of config it can take forever to copy across.

    I think using

    #copy xmodem: startup-config

    and then sending the config file using xmodem_1k from a terminal emulator like tera term seems to work OK.

    If you don't have connectivity to copy it over with TFTP/FTP then you just need to go slow and paste the config in small portions.

    you can xmodem over the console port.

    Yeah, but thats way more trouble than pasting it in slowly.

    I concur. If I cannot TFTP it in, then I simply copy it in small chunks.

    actuly I have just been doing this today, things you find out after you ask a question :) .

    it really simple all terminual emulators suport it.

    #copy xmodem: startup-config

    no need to give any file names.

    then simple click file >> send/transfer in the terminal emulator, and chose the config file, no re-naming or opening it up. All sorted out for you. and for a config file with 1000 lines of config, you can be sure its copied correctly and you don't miss out lines.

    much quicker than slowing down the paste speed or pasting in chunks

    we can have a race some time ;)

    I had this issue when I would paste in configs from hyperterminal, I started putting an ip on vlan1 put my laptop in the same subnet, and TFTP the config over. Before I did it this way I ended up sending out equipment that did not have any VTY information configured. The pasting would stop just prior to that so it always looked correct. That was a PITA lesson I wont soon forget :)

    Per line or per char? I've never had a problem in TT using 5 msec/char.

    Manually config just enough to get connectivity then tftp.

    I prefer Xmodem and I would never use HyperTerminal. Too many problems in the past.
