TL-SG3428XMP(UN)_V1.6_1.0.8 Build 20220909

It is recommended to reboot the switch before upgrading, especially if the memory usage exceeds 60%.

New Features & Enhancements:
1. Increased the number of VLAN Interfaces to 32.
2. Adapted to Omada SDN Controller v5.3, increased the number of LAN in VLAN type to 256.
The following new features are available in Standalone mode:
3. Added support for Ethernet Ring Protection Switching (ERPS), which can be configured via CLI.
4. Added support for DHCPv6 Relay, DHCPv6 L2 Relay, and RA Guard feature.
5. Added Log and SNMP Trap for IPv6 DHCP Filter.
6. Added support for DHCP Auto Install.
7. Added support for customizing DHCP Options.
8. Added the new SDM template "IPv6 combined ACL", "packet content ACL" and "enterpriseMix".
9. Added support for SFP+ port speed auto-negotiation. When you connect an SFP module to an SFP+ port, the SFP+ port can be automatically changed to 1G speed mode, no longer requiring manual modification. Note that this requires the switch to be able to correctly recognize the optical modules, and is recommended to be used with TP-Link optical modules.
10. Increased the max MVR group to 4k.

Bug fixed:
1. Fixed the bug of incorrect traffic statistics in Omada Controller mode.
2. Fixed the bug that the RADIUS packets with specific fields caused the switch to crash.
3. Fixed the bug that Combined ACL failed to block traffic between Layer 3 networks.
4. Fixed the bug that the switch may fail in controller mode after upgrading the previous firmware version, which has been withdrawn.

Notes:
1. For TL-SG3428XMP(UN) v1.0 and v1.6.
2. This firmware is fully adapted to Omada SDN Controller v5.3 and above.
