NextPort SPE Firmware and Dial Feature Card Overview

NextPort SPE firmware is software that drives the DSP portion of the Cisco NextPort dial feature cards (DFCs). NextPort firmware includes NextPort SPE firmware and Cisco IOS software code that together drive the NextPort DFC cards.

You cannot load new NextPort firmware without getting a new Cisco IOS software release that includes the new code. However, you can load just the NextPort SPE firmware.

NextPort SPE firmware runs on the NextPort DFC60, DFC108, and UPC324 DFCs on the Cisco AS5350, Cisco AS5400, Cisco AS5800, and Cisco AS5850. The ports on these modules can support both modem, voice, fax, and digital services and can be aggregated at any of the following levels:

•Slot level of the NextPort module

•SPE level within the NextPort module

•Individual port level

For more information, refer to the "Related Links" section.

Finding Software Bugs

If you have an account with Cisco.com, you can use Bug Navigator II to find caveats of any severity for any Cisco software release. You can reach Bug Navigator II on CCO at
Service & Support: Online Technical Support: Software Bug Toolkit
Or at

Downloading NextPort SPE Firmware

NextPort SPE firmware is downloaded using the spe command. The spe command allows firmware to be downloaded to the service processing element, or SPE.

SPE Download Tasks

To download modem firmware, follow these steps, beginning by entering the spe command:

---

Step 1 Enter the spe command and subcommands, one configuration command per line:

Router# configure terminal

Router(config)# spe slot/spe_begin slot/spe_end

Router(config-spe)# firmware location system:/ucode/np_spe_firmware1

Router(config-spe)# ^Z

For example, the following display shows a Cisco AS5400 SPE download to all modems in Slot 1 (that is, all modems on a feature card containing 18 6-port modem modules). The modem code resides in the Flash memory, and the modem code filename is dfc108-firmware.1.1.6.81.

Router(config)# spe 1/0 1/17

Router(config-spe)# firmware location flash:dfc108-firmware.1.1.6.81

Step 2 Copy the configuration from running RAM into NVRAM:

Router# copy running-config startup-config

Download occurs when the modems become available and shows the SPE firmware upgrade option defined (default: busyout). The spe command generates NVRAM modem download and configuration file entries.

---

Note If the configuration is not saved as described above, download of the firmware specified with the spe command will not occur after the next reboot.

---

For detailed information on the spe command, refer to the Cisco document,
SPE and Firmware Download Enhancements.

Technical Assistance Center

The Cisco Technical Assistance Center (TAC) is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two levels of support are available: the Cisco TAC Web Site and the Cisco TAC Escalation Center.

Cisco TAC inquiries are categorized according to the urgency of the issue:

•Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.

•Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.

•Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.

•Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

The Cisco TAC resource that you choose is based on the priority of the problem and the conditions of service contracts, when applicable.

Cisco TAC Web Site

You can use the Cisco TAC Web Site to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to this URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to this URL to register:

http://www.cisco.com/register/

If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco TAC Web Site, you can open a case online by using the TAC Case Open tool at this URL:

http://www.cisco.com/tac/caseopen

If you have Internet access, we recommend that you open P3 and P4 cases through the Cisco TAC Web Site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.

To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to this URL:

http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml

Before calling, please check with your network operations center to determine the level of Cisco support services to which your company is entitled: for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). When you call the center, please have available your service agreement number and your product serial number.
