Hi,

Have you ever received output like this while you are copying an image to flash on a router? (in this case 2611XM running 12.3(22))?

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!O!OOOOOOOOO!OOOOOOOOOO!OOOOOOOOO!
O!OOOOOOOOO!OOOOOOOOOO!OOOOOOOOO!OOOOOOOOOO!OOOOO
OOOOOO!OOOOOOOOOO!OOOOOOOOOO!OOOOOOOOOO!OOOOOOOOO
O!OOOOOOOOO!OOOOOOOOOO!OOOOOOOOOO!OOOOOOOOOO!OOOO
OOOOOOOOO!OOOOOOOOOO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

There's enough room in the flash ....

The bandwidth utilization of the TFTP download jumped from 200kbps to 500kbps while I was receiving this message.

Copy isn't done yet ... hope it succeeds ...

Thanks,
Adam

Make sure you compare the md5 hash after the upload/download is done
before you try to use the image.

Thanks guys. Image copied successfully, and I verified the MD5 hash as well,
as suggested. I appreciate the help and the peace of mind of knowing the
router will most likely reboot!

The "O"s indicate that a TFTP packet was lost along the way. As long
as it completes the file should be OK but as Vijay says double-check
the hashes.

Probably because it was sending retransmissions.

"O" actually means that the packet(s) arrived, but out of order.

General Output Conventions for Copy Operations

During a copy operation, any of the following characters may be
printed to the screen:

•A pound sign (#) generally means that a Flash memory device is being
cleared and initialized. (Different platforms use different ways of
indicating that Flash is being cleared.)
•An exclamation point (!) means that ten packets have been transferred.
•A series of "V" characters means that a checksum verification of the
file is occurring after the file is written to Flash memory.
•An "O" means an out-of-order packet.
•A period (.) means a timeout.

The last line in the output indicates whether the copy was successful.

I ran into this recently when tftp was being throttled by Control
Plane Policing. O generally means a dropped packet.

Actually, isn't that O = out of order packet? Are there multiple active
paths between the router and TFTP server? Perhaps cef per-packet on
serial links to the router?

TFTP will not send a second until the first is acknowledged.
It will continue resending the same packet until an acknowledgement is received.
There is no windowing which would allow 'out of order' packets.

The Os mean out of order.

Which means what you are TFTPing is over 18.4MB and crappy TFTP
servers (Solarwinds, Cisco...) reset their sequence number to 0 after
18.4MB... Get 3CDaemon

Or use copy ftp://user:***@ftpserver/pathtoios as it'll run faster
anyway and not have any issues with IOS file sizes.

Unless it corrupts the image when you use ftp instead of tftp (hi SRA!).

Or crashes your router (hi 12.2(18)S5, has been fixed meanwhile AFAIK).

Daniel (still tftp-ing, which usually works)

I second that - especially on high latency paths, copying through FTP or HTTP
is more responsive and robust than TFTP.

I also make a habit of squeeze-ing flash before TFTPing - a bunch of 3500XL
switches were painfully slow at copying IOS off a TFTP server until I squeezed
the flash, then they worked like a dream.

Yes,

mismatching speed & duplex of the port.
