Enhancements:
- Updated help text to correct the explanation of the wildcard mask meaning under IPv4 ACL rule. A wildcard mask of 255.255.255.255 now indicates that none of bits are important. A wildcard of 0.0.0.0 indicates that all the bits are important.
- Change Syslog time stamp format, following ISO 8601.
Bug Fixes:
- Fixes an issue that the switch bypasses 802.1x authentication if a device such as an IP phone is connected to a voice VLAN on the switch.
- Fixes the problem that IP configuration setting cannot accept address ending with x.x.x.255.
Security Fixes:
- This firmware addresses security vulnerabilities. For more information about security vulnerabilities, visit https://www.netgear.com/about/security.
Warnings:
Read and follow these warnings before updating a firmware version:
- We recommend against downgrading the firmware image to 1.0.2.2 or earlier version after updating to 1.0.4.4 or later versions.
- Because HTTPS has been disabled by default since v1.0.2.2, the device UI Home page does not display automatically after using HTTPS to upgrade to this firmware version. Workaround: Open a new web browser tab and type the switch’s IP address to access the Home page.
- After HTTPS is enabled manually, accessing device UI via HTTP will be redirected to HTTPS automatically.
- Default community string “Private” and “Public” for SNMPv1/v2 are not available in newer firmware. Workaround: Set a different community string before updating the firmware.
- Authentication protocol for SNMPv3 automatically changes to “MD5” if the current setting is “None”. Workaround: Rest the Authentication protocol to SNMPv3 after upgrade.
- The default setting for the Smart Control Center (SCC) Management option changes from enabled to disabled. Note: The SCC Utility can still discover the switch.
