Unable to upgrade IOS remotely

[shoaib sheikh]

Hello everbody,

I am trying to copy IOS image from core switch (making it as tftp server) to L2 switch.

For some switches the copy was successfully done, IOS from core switch's bootflash to L2 layer switch bootflash was copied.

For some L2 switches it is not happening while copying after sometime suddenly session is getting closed automatically and no image is copied.

On L2 switch i have used command:

L2switch# copy tftp: bootflash:

Then it will ask for tftp server ip and source file and destination file name.

Can anyone tell me what is the issue and how can i solve it.

Try using FTP instead.

Also switch shoudl have flash, not bootflash.

Thanks for reply Paolo

I am making source switch as ftp server as:

ip ftp username "username"

ip ftp password "password"

no ip ftp passive

ip ftp source-interface "management vlan interface"

on destination switch:

copy ftp://username:password@"management vlan ip"/"name of IOS" bootflash:

Then it asks for destination filename

after that it throws an error message that cannot open tftp:// some message

Just to let you know we have upgraded several switches using tftp and bootflash in command because these type of switches does not have flash as option in command. Only there are some switches which we are not able to upgrade remotely.

Can you tell me the exact procedure for doing it.....

You cannot  not use "source switch". Use a real FTP server.

Hello

Make sure the flash has enough memory to hold two images, if not you will need to delete the exisitng ios, ( but make sure you dont reload the switch/router)

Host

tftp-server flash:/directory/xxx.bin

recipient

copy tftp:xxxx.bin flash:

Address or name of remote host x.x.x.x

Source filename xxxx.bin

Destination filename xxxxx.bin
