Bug Fixes:

This firmware addresses the following bugs:

Fixes the issue where the SNMP access times out on a stack with 6 or more units. [MS-3746]
Fixes the issue where the switch crashes when the configuration is cleared immediately after switch is turned on. [MS-4448]
Fixes the issue where packets drop even though conditions do not match with the outbound policy. [MS-4801]
Fixes the issue where the AGM731F or AGM732F modules connect the switch to another switch by setting a fixed 1G speed on the SFP+ port, and the link does operate successfully after the switch restarts. [MS-4862, CE-6806]
Fixes the issue where the switch crashes in a network loop condition. [MS-4867, CE-6741]
Fixes the issue where the switch crashes when protocol logging is enabled and the Tech Support file is generated from the Main UI or AVUI of the switch. [MS-4919]
Fixes the issue where the 224.0.1.129 PTP packet is not forwarded through the stacking port. [MS-4953]
Fixes the issue where the IGMP querier does not elect correctly when MSTP is configured. [CE-6738]
Fixes the issue where the switch does not lease more than 2000 IP addresses. [CE-6745]
Fixes the issue where AVB systems only with 100 MB capability do not synchronize when they connect to certain ports. [CE-6848]
Fixes the issue where you cannot use the user name in the password. [MS-5038]
Fixes the issue where the MLD query packets flood in a large network. [CE-7028]
Fixes the issue where you can use insecure SSH key exchange (KEX) algorithms “diffie-hellman-group-exchange-sha256” and “diffie-hellman-group14-sha1” for secure connection. [CE-6562]
Fixes the issue where the switch does not respond when it connects through the main UI, SSH, or serial console after you download the Tech Support file. [CE-6900]

Known Issues:

This AV UI contains the following known issues:

An Auto-LAG does not form after you apply the G&D KVM-over-IP AV profile.

Workaround: Form the Auto-LAG before you apply the G&D KVM-over-IP profile.

Additionally, apply the following command to the LAG and trunk interfaces to enable G&D device discovery: macfilter adddest 01:0F:F4:00:00:00 <pvid>

This firmware contains the following known issues:

Auto-LAG Global PTP mode in main UI configures PTP boundary clock on the newly formed Auto-LAG interface when it is enabled on the switch models that support PTP boundary clock mode.

Workaround: Do not enable Auto-LAG Global PTP mode from main UI if you do not use the PTP boundary clock mode of operation and configure it manually on the newly formed Auto-LAG interface.

G&D Control Center IP devices fail to link up with the switch

Workaround: Manually set the switch port speed to 1G to establish the link.

This firmware includes a configuration migration process that transitions the default web browser protocol from HTTP to HTTPS. When you upgrade to this firmware and import an older configuration with HTTPS disabled, HTTPS becomes enabled.

Workaround: Reconfigure the web browser protocol settings manually after you perform a firmware upgrade or import an older configuration

During your initial log in, you must set up a password to access the switch. However, if you access the main UI before you set up a password and simultaneously set the password in the AV UI, the switch console might lock for up to 15 minutes.
Workaround: Configure a password in either the main UI or the AV UI to avoid this lock up issue.
If you upload only the private key or the certificate before you enable HTTPS, the system enables the HTTPS service but it fails to operate correctly because the configuration is incomplete. A factory reset does not fix this issue.

Workaround: Ensure both the private key and certificate are fully uploaded before you enable HTTPS. If the issue still occurs, remove the incomplete HTTPS-related private key or certificate, and disable HTTPS before reconfiguring.

The four 25G ports of models M4350-44M4X4V, M4350-24X4V, and M4350-24F4V can operate at either 10G or 25G speed but not simultaneously at 10G and 25G speed.
A stacking link works only at the highest speed that the port supports. For example, if you configure a 25G port in stack mode, the port can operate only at 25G and not at 10G. Therefore, you cannot establish a stacking link if a 10G port and a 25G port are interconnected.

Warnings:

Read and follow these warnings before updating your firmware:

HTTPS is set to default web browser protocol from firmware version 14.0.6.10 and newer versions. The default certificate is self-signed, so a browser warning might display when you log in. To avoid this warning, you can download your own certificate that is issued by a trusted Certificate Authority (CA).

General Information:

The boot code remains at the existing version 1.0.0.15 in this switch firmware.
The process of upgrading the firmware and boot code takes about three minutes. Apply the “update bootcode” command from the command line interface. Do not switch off or restart the device during the upgrade process.
AppMgr is upgraded to version 1.0.4.27 in this switch firmware.
Insight and Engage/AV UI are mutually exclusive. This means you can only use one of these options to configure and manage the switch, not both.
If the encrypted password in the configuration file does not adhere to the NETGEAR password policy, when the configuration file is loaded on the firmware version 14.0.6.9 or later, you must create a new password during the initial login.
