The firmware upgrade feature, designed for ease and security, facilitates the seamless updating of the cellular modem's firmware across multiple Cellular devices. Acting as a centralized controller, Catalyst SD-WAN (vManage) serves as the command center for managing and distributing firmware updates. This ensures that all devices connected to the network receive the latest firmware version, all made possible by the new UX2.0 Firmware Upgrade workflow.
From Cisco Catalyst SD-WAN Control Components Release 20.12.1:
Cisco Catalyst Wireless Gateways (CG113-4GW6)
Cisco Catalyst Cellular Gateways (CG522-E, CG418-E)
From Cisco Catalyst SD-WAN Control Components Release 20.14.1:
Cisco ISR1100 and ISR1100X Series Platforms
Cisco Catalyst 8200 Series Edge Platforms
Cisco Catalyst 8300 Series Edge Platforms
Upgrade Cisco Catalyst SD-WAN (vManage)
Upgrade all Cellular devices.
Spin up a Remote Server for firmware image storing.
After downloading a firmware upgrade file from software.cisco.com, do not change the filename. A device uses the filename to determine which firmware upgrade files are relevant to it.
Cisco SD-WAN Manager only supports upgrading the currently active firmware type. For example, a device may have five different firmware types, such as generic and firmware for four specific carriers. Only one firmware type can be active at a given time, and Cisco SD-WAN Manager upgrades only the active one.
Firmware downgrade is not supported by Cisco SD-WAN Manager.
In order to upgrade the firmware, the device will select the highest version firmware file (.cwe) from the remote server. If there is no corresponding PRI file (.nvu) with the same highest version, the device will not be able to proceed with the firmware upgrade.
There are 3 files for the firmware upgrade of the CG522-E cellular gateway: •. • .CWE (based firmware file) •.NVU (carrier PRI file) • .NVU (OEM PRI file).
Note: Before you begin this procedure, make sure you have met the following modem firmware requirements:
For the CG418-E cellular gateway, there is 1 bundle file for firmware upgrade. • .BIN (bundle file that has based firmware + all carrier PRI + OEM PRI files).
Note: To update all 3 versions (based firmware, carrier PRI, and OEM PRI), only 1 firmware upgrade process is needed.
In this section, we will add the AWS Remote Server and firmware location in SD-WAN Manager. This feature lets you upgrade your device using firmware images stored on a remote server. You register a remote server with Cisco SD-WAN Manager and add the locations of firmware images on the remote server to the Cisco SD-WAN Manager software repository. When you upgrade the device, it can download the new firmware image from the remote server.
For this example, we have created a dedicated AWS Remote Server. Please take a look at the screenshot for detailed information.
Enter Server Name: ex. (“Firmware Server”)
Enter Server IP: <IP address>
Select Protocol: SCP
User ID: username
Password: password
Image Location: home/path/directory
VPN: Management VPN ex. (“0”)
In this section, we will go through the Firmware Upgrade workflow to instantly upgrade the firmware on the devices on the scheduled upgrade. This feature introduces a guided workflow through which you can upgrade the software image on your Cellular devices and monitor the status of the software upgrade. You can schedule software upgrades for Cellular devices using Cisco SD-WAN Manager.
A scheduler enables you to schedule the firmware upgrade workflow either now or Later. If you choose to schedule an upgrade for a later time, you can enter the Start Date and Start Time and Select the Time Zone.
Use the following steps to start the firmware upgrade workflow:
Note: You cannot select devices with different versions, only devices with the same version can be upgraded. Up to 40 Cisco IOS XE SD-WAN devices can be upgraded and rebooted in parallel, depending on CPU resources. Devices with identical SITE IDs will be upgraded sequentially, and devices with different SITE IDs will be upgraded in parallel. |
