Strange TFTP problem via Pix

Discussion in 'Cisco' started by Christoph Gartmann, Mar 16, 2006.

  1. Hello,

    the following scenario:

    Router -------- Pix ---------- TFTP-Server

    The router is a Cisco 2851, the Pix is a 515 with software 712. I tried to
    upgrade the ROMMON on the router via
    upgrade rom-monitor file tftp://a.b.c.d/c2800nm_rm2_srec.124-1r
    and I got:
    Loading C2800NM_RM2_SREC.124-1R from a.b.c.d (via GigabitEthernet0/0):
    !!... [timed out]
    I tried the same with a direct connection between the router and the tftp
    server and it worked. So it must be the Pix.

    I have no problem saving the router's configuration to the very tftp server.
    I am able to upgrade the IOS software via this tftp server. All with the Pix
    in-between. So what is different with this ROMMON file? I noticed that it is
    larger than a config file but a lot smaller than an IOS image. On the other
    hand it is all ASCII. I enabled debugging on the Pix and got:

    CCO shows 7.1(2) as having being released very recently

    Did you have the same issue with 7.1(1)?

  3. Yes, had to downgroade because 7.1(2) causes the inside interface to no longer
    accept packets after about one hour :-(

    There are MANY TFTP related bugs in 7.x software. Most however are
    associated with TFTPing to/from PIX ; not thru PIX.

    If you have a support contract you should open a case with teh Cisco
    TAC.
