Updating IOS from a tftp server 2

[silverhairb]

I've got a 3640 router in the lab that doesn't seem to want to copy a version of IOS from a tftp server. Its running IOS 11.2(23) j-mz. I'd like to try to get it running on 12.3(15) that I have on another 3640 and backed-up to a tftp server. Lab use only.

It appears that the copy format needs to be something like:

router# copy tftp: c3640-js-mz.123-15.bin flash: [maybe something here?]

but seems to have a problem with defining the destination starting with "flash:" which seems to give the error. Just using the command:

router# copy tftp: flash:

gives an error ^ under the first "t" in "tftp:".

Copying from the router to tftp: did require the filename in the command and worked OK. Copying from flash to / from a PCMCIA card in slot0 works. I'd use the PCMCIA card but its 8meg and the image is more than 16meg.

I'd certainly like to try to update that 3640 if I can.

Thanks in advance,

Bill,

Example 1: Copy the image to flash: from TFTP server
Upgrade the new image from a TFTP server. Use the copy tftp: flash: command in order to copy the image from TFTP server to the flash.

3600>enable
Password:xxxxx
3600#copy tftp: flash:
Address or name of remote host []? 10.10.10.2

!--- 10.10.10.2 is the IP address of the TFTP server

Source filename []? c3600-adventerprisek9-mz.124-12.bin
Destination filename [c3600-adventerprisek9-mz.124-12.bin]?y
Accessing tftp://10.10.10.2/c3600-adventerprisek9-mz.124-12.bin...
Erase flash: before copying? [confirm]y

!--- If there is not enough memory available, erase the Flash.

!--- If you have sufficient memory you can type n and press enter

Erasing the flash filesystem will remove all files! Continue? [confirm]y
Erasing device... eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

This should work, I have done it with 2600's over 100 times!!!!

Bill,

If all else fails and you have a backup copy of the IOS, erase flash and reboot and then you can use ROMON and TFTPDNLD or don't even erase FLASH just boot to ROMON and try it but try stuff below first >>>>>>>>>>>>>>

If I had a dime for every time a student erased FLASH instead of NVRAM I would be RICH !!!!

But the copy tftp: flash: should be working or ........

If not try 3600# copy ? and see what it brings up and add that and do the ? again until you have the whole command

Hi Gene,

I tried those.

I initially tried a procedure for copying under rommon. The TFTPDNLD command wasn't recognized. Erased flash and booted from a PCMCIA card to the older version of IOS (from before upgrading flash from 8 to 24meg).

The copy tftp: flash: just ain't workin' in any variation of the command I've tried. I've used the copy command on other routers, but this one with its early IOS is dealing me fits. (This particular unit doesn't like fast ethernet either, but that's for another thread.)

Any ideas? (TIA!)

The copy tftp: flash: just ain't workin'"

No colon!!!

router#copy tftp flash

That's it! It asks you the rest!

Burt and Gene,

Many thanks! I'm making this soooo much harder than it needs to be. I'm expecting a lot of complexity when none exists.

The 3640 is upgraded and supporting FE's under the 12.3 IOS.

Break time. Then on to the beast (3660).

Burt,

I was womdering about those stinkin' ":"'s, that is why I went up to Cisco and copied it down.

Bill,

Whenever you are stuck (and we aren't around ) - just do 3600# ? the "?" should give you a list of everything you can do next, or what is needed to complete the command a little further, you see that "copy" is supported here (I always get screwed up as to what can be done at 3600# and what needs to be done at "config t") then you do 3600# copy ? and get the next thing to add, then 3600# copy tftp ? .........

Have fun with that 3660 beast, make sure you throw it some raw meat before you try to configure it

Thanks, Gene. I tried that, but the answer was a bit too cryptic, even for an old crypto geek. I do recall that the "?" returned values without the colons, but it didn't click at the time.

It is a beast. I removed the second power supply from the 3660. The sound level reminded me of a "Who" concert I attended in 1969. Its better now and it doesn't spit out the error messages it did when running on one PS with both installed.

Bill,

You WILL get used to what they are saying when you use "?"

When I am in my lab at work, the computers in the lab are connected to the switches in the lab so you have only a local Intranet that you are connected to for "help", if I need the Internet I need to walk over to my office, not far but I find it faster to just use the help "?".

There are a few things like setting "time" that I just have to look up with help everytime!!

I only wish Linux CLI supported the '?"

The complete deal would be in a UNIX fashion...

Neato, eh? You can store different config files for your router or from other routers---like a LOT, since they're 2KB...and do a more or cat, like UNIX.

WHOOPSIE..."cat" does not work...what kinda crap is THAT???lol

[maczen]

hmm.. With a little TCL your configs could change dynamically depending on environmental changes (this could include IOS changes from say IP Plus to Advanced Security in the event of a network attack.. suspected net attack) Kind of cool if you think about it! I am going to have to play after this cert! LoL

In Linux, there's "help", "man" (-k).

That's a switch config stored on my 2620XM, that's all.

Gene and Tad---that would make a good bug---put a switch config on a router and boot system flash:switch.confg...muahahahahaha...

Burt

 

[maczen]

A switch config on a router?? That is just wrong! LoL

By the way, don't think you can compare MAN/HELP to the infamous Cisco '?'

[maczen]

Now if you really wanted to be a meanie write a TCL script (if possible) that says "RTFM" every time a user types "?" in their CLI! LoL

Too funny!!

What would REALLY be cool is to use alias commands...

alias exec show run show ip route

lol

Burt,

We had a "real" &*#$@#@# in class once and we did that to him - he was a "know it all" or at least thought that he knew it all, I love it when students can add to the class - WHEN THEY CAN ADD TO THE CLASS

He learned his leason that day!!!
