Version Feature Content
This is the first upgradeable ROMmon image for the NPE-G100.
Upgrading ROMmon for the NPE-G100 is optional. The built-in ROMmon images are completely functional on any Cisco IOS release, although upgrading to this ROMmon image may be helpful in resolving some caveats. For a list of known caveats that can be corrected by upgrading to this ROMmon image, see the "Resolved Caveats" section of this document.
There are no Cisco IOS restrictions with this ROMmon software image. The NPE-G100 ROMmon software image is compatible with any Cisco IOS image, including non-12.2S Cisco IOS Release images, running the Cisco 7304 router. The Release 12.2(22)S portion of the filename is used only to provide a guideline for when the ROMmon image was released in relation to the Cisco IOS release image.
This ROMmon image can be used only with the NPE-G100 processor on the Cisco 7304 router. For information on the NSE-100 ROMmon image, see the Release Notes for Cisco 7304 ROMmon Image Release 12.1(12r)EX1 document.
The process for upgrading the ROM monitor software image is available in the "Upgrading ROMmon" section of the Network Processing Engine Installation and Configuration guide. This section of the Network Processing Engine Installation and Configuration guide can be accessed by entering the following URL:
The 12.2(22r)S ROMmon image for the NPE-G100 can be downloaded from the following URL:
This section documents the known severity 1, 2, and 3 open caveats for this ROMmon image and the caveats that can be resolved by installing this ROMmon image.
There are no known severity 1, 2, or 3 caveats associated with the ROMmon image.
The following caveats can be resolved by upgrading the ROMmon image:
While reading or writing to Flash memory, you may see an unexpected status timeout error. There are no known workarounds.
A Cisco 7304 using an NPE-G100 that is configured to reboot automatically may not reboot automatically as configured when a fatal exception error is experienced.
Workaround: One workaround is to power cycle the router. A break signal can also be sent using the console connection to the NPE-G100 while the NPE-G100 is in the process of rebooting automatically. After sending the break signal, reset the router from ROMmon.
After a watchdog reset, the reason for the reset in various command outputs (such as show version) is incorrect. There are no known workarounds.
If a router is mistakenly configured to autoboot a Cisco IOS image for a platform other than the Cisco 7304 router, the Cisco 7304 router will hang as a result of a continuous TLB exception loop.
Workaround: Control the router by sending break signals from a Telnet console. If the router does not respond, power cycle the router and retry sending the break signals from the Telnet console. Once you have gotten to the ROMmon prompt, boot the router using a valid Cisco IOS image by entering the boot system command.

(S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool automatically provides recommended solutions. If your issue is not resolved using the recommended resources, your service request will be assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:
For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—Your network is "down," or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
