Re: C85x/C87x ROMMON Upgrade

What problem are you trying to fix?

You say your smartnet contract ran out some months ago, so I understand that you have been using this router for some time. When did it run into these problems?

I would expect some problems on an ADSL router, but on an Ethernet to Ethernet device like the 871 it is less usual. Perhaps a rommon upgrade is not required to fix the problems with your router. Please, outline the problem with the router. I am sure, someone at this forum will be able to help you.

Hi Sobrado,

The problem I have with my 871W is a fairly large bug which is outlined in CSCsd60259. What basically happens is that when the router boots, for a brief period (whilst rommon is organising the file system and preparing the IOS) it bridges the LAN and WAN interfaces. As many cable modems will bind to just one MAC address (unless rebooted), if a PC connected to the router discovers the network is disconnected due to rebooting the router, it will send out another DHCP request and bind with the cable modem when in the rommon stage. Therefore when the router tries to get dhcp from the cable modem, the modem refuses. C870_RM_ALT.srec.123-8r.YI3 fixes this. Does that make sense?

Regarding SmartNet, I have never has a SmartNet on this device. I work for an ISP and have always got files that I have needed with the company's contract. However, I have moved position now and find it harder to request files from them.
The cisco devices I own are 2nd hand and have mostly come from customer sites once they have finished with them. I use them for the only purpose of training for cisco qualifications so it is not financially viable to buy this equipment new (with a smartnet contract) just for learning purposes.

It is illegal for others to provide you with router firmware, and against the TOS of the site to solicit it here.

Perhaps you could:

1) Either not reboot the cable modem at the same time you reboot the router. This way the cable modem would already have the MAC from the router and deny the request to the PC. When the router comes back up it would be able to properly obtain a lease
2) Unplug your PC's network when you reboot the router.

Perhaps you could contact Cisco, explain your situation, and see if they can help. If they can't, then it would not be "legal" for anyone here to otherwise provide this to you either.

Technically this may not be legal either. The company's contract is for the devices which they own so unless your Cisco devices are company owned and you just use them with their permission you should not load SW downloaded/obtained by the company onto them.
