Chapter 10 Cisco WAN Manager Operations

Downloading Software and Firmware

Cisco IGX and Cisco BPX nodes maintain the primary version of the network operating software in RAM of the active controller card. If redundant controllers are installed, the standby controller maintains a secondary version, which may or may not be the same release level as the primary. The primary version of the operating software can typically be the same release level on all nodes in the network.

All Cisco IGX and Cisco BPX card modules also have card and version specific firmware, which is stored in flash memory on the front card. If applicable, firmware upgrades are downloaded to the switch controller card, and distributed to the other cards within that switch. Cisco IGX and Cisco BPX nodes do not provide long-term storage of firmware images on the controller card.

Cisco MGX nodes do not use network-switching software as on the Cisco IGX and Cisco BPX nodes. The Cisco MGX nodes use firmware that controls shelf and card operation. The Cisco MGX controller retains a copy of firmware for service modules, and upgrades are downloaded from a management station.

The TFTP/FTP protocol downloads software and firmware images from the CWM workstation to WAN switches.

The CWM Image Download downloads software and firmware images, and monitors the download process.

Note A CWM workstation is not required to download the software images. You can download the software images using any machine that can run a FTP client/server process.
