That's an interesting one. Attached the release notes GS110TP & GS108Tv2 Firmware Version 5.0.2.22 from my local archive. Would be great, if a Netgear rep could figure out what was going on DaneA JohnC_V Marc_V JeraldM NiveditaP   please.

GS110TP & GS108Tv2 Firmware Version 5.0.2.22

Please refer to the following documents before upgrading your firmware. It is very important to follow the upgrade process documented due to changes in firmware and boot code.

• SCC 1.1 release notes
• Upgrading GS108Tv2 and GS110TP from 5.0.1.x to 5.0.2.x

Bug Fixes:

• Fix the problem that unplugging and plugging the cable continuously with RSTP enabled could cause the switch to reboot.
• Fix the problem that packet always get forwarded to Voice VLAN when its source MAC matches a predefined OUI even when the OUI is deleted.
• Fix the problem that GS110TP PoE Timer (System > PoE > Advanced > Timer Schedule Configuration) does not work past midnight.
• Fix the problem that entries in Memory Log are not showing the correct time zone.
• Fix the problem that when switch receives a Kiss of Death (KOD) packet from the SNTP server, it won't log the event into Memory Log.
• Fix the problem that when Clock Source (System > Management > Time > SNTP Global Configuration) is SNTP, the clock occasionally appears to either running behind or jumping ahead of the real time.
• Fix incorrect description of context help for the "APPLY" button on the Web GUI.
• Change default setting of "Validate IGMP IP Header" (Switching > Multicast > IGMP Snooping > IGMP Snooping Configuration) from Enable to Disable.
• Fix the problem that the device does not retain the configuration of VLAN 2 as the management VLAN after a reboot.
• Fix the problem that backup configuration file shows PoE schedule dates are one month earlier.
• Fix the problem that LLDP-MED is not advertising voice VLAN to IP phones.

Known issues:

• While the link is up, port cannot be removed from a VLAN if it is also member of a LAG.
  Workaround: Remove the link or remove the port from the LAG first. 
• After setting the maximum number of allowed static locked MAC address to zero (under Security > Traffic Control > Port Security > Interface Configuration), no static MAC address can be added even when port security is disabled. 
  Workaround: Change back the "Max Allowed Statically Locked MAC" from 0 to 20.
