RSTP Enable/Disable (Default: Enable);
#2
VLAN Enable/Disable (Default: Disabled);
#3
SFP port fixed speed, ON as 100M (Default: 100/1000M Adaptive);
Notes:
1. RSTP switches to the ON position, which indicates RSTP is in disabled status.
2. VLAN switches to the ON position, which indicates VLAN is in enabled status. All LAN ports are
only able to communicate with the SFP uplinks when this option is enabled.
3. To take effect the DIP Switch function while the ethernet switch is in operation, there is a need
to reboot the Ethernet switch after tuning the DIP switch.
