• Fixes the issue where the password becomes plain text in the console when you are saving the configuration in the AV UI.
• Fixes the issue where incorrect information is shown when you display the DHCP helper address for a VLAN interface.
• Fixes the issue where the switch reboots unexpectedly when you reset VRRP.
• Fixes the issue where Multicast Forwarding Database (MFDB) inconsistencies occur between two switches that are configured for multi-chassis link aggregation (MLAG) when an Ethernet client sends an IGMP leave message.

Firmware Update Instructions Using the AV UI:

You can update the firmware through the AV UI.

You can update the firmware for the switch image only, for example, M4500-v7.0.3.12_2.2.6.9.deb. That is, you cannot update the firmware that combines the switch image and Linux OS.

To update the firmware:

1. Download the firmware file to the computer that you use to access the AV UI.
2. Launch a web browser.
3. In the address field of your web browser, enter the IP address of the switch. The login page displays.
4. In the Login Name field, enter admin as the user name, in the Password field, enter your local device password, and click the AV UI Login button. The local device password is the password that you set up when you first logged in to the CLI. The Overview page displays.
5. Select Configure > Maintenance. The Maintenance page displays. Note: The switch can hold two firmware versions. If it does, the page displays the active firmware version. The CLI lets you manage firmware files, and change from one version to another. The AV UI lets you update the firmware but does not let you manage firmware versions. If you update firmware using the AV UI, the new firmware becomes the active firmware.
6. Click in the Browse Field field, navigate to the firmware file, and select it.
7. Click the Upload button. A pop-up window displays the progress of the firmware file upload.
8. After the upload completes, in the pop-up window, click the Reboot Now button. The firmware upgrade process starts. During the firmware upgrade, do not power down the switch. The switch reboots and restart with the new firmware version. When the process is complete, you can log in again to the AV UI.

Firmware Update Instructions Using the CLI:

Starting from firmware release 7.0.3.x, the same firmware file supports both models. Download the “onie-installer-x86_64-netgear_m4500_dnv-7.0.3.x_sign” image file to upgrade the M4500-32C and M4500-48XF8C.

Starting from firmware release 7.0.1.10, only signed firmware images are supported. You cannot update the firmware directly from an unsigned version (that is, from release 7.0.0.20 or an earlier release) to a signed version such as release 7.0.1.x. Instead, you must update to a transition ONIE image version first, and then to the signed ONIE image version 7.0.1.x as shown below:

1. Update from unsigned firmware version 7.0.0.x to transition firmware version 7.0.1.6.
2. Update from transition firmware version 7.0.1.6 to signed firmware version 7.0.1.x.

The current transition image is version 7.0.1.6, which provides options to upgrade to a signed or unsigned image version as shown below. In the transition firmware, “with verification” refers to the signed firmware image, and “without verification” refers to the unsigned firmware image. Do not use the transition firmware in a production environment.
