Nebula switch management - no Voice VLAN on trunk port
Nebula does not appear to allow 'trunk' ports (which are required for multiple 'tagged' VLANs) to be assigned a voice VLAN via LLDP. We design our networks as 'device agnostic' e.g. plug any device into any port and this lack of functionality causes a problem. Is there a way to provision 'LLDP voice VLAN' and 'multiple…
NCC: Isolate a Hyper-V VM in a separate VLAN but allow access by RDP
Is something like this possible with NCC (e. g. with USG Lite 60AX + XMG1915)? I created an interface for VLAN 3 = own IP subnet. I have a VM running on a PC (Hyper-V-Host) connected to switch port 3. I configured in the Hyper-V network configuration on this PC for this VM to use VLAN 3. So, this VM gets an IP in the new…
More than one LAN interface config on security router (SCR50AXE)?
Nebula allows it, though it is said that the security router does not support to link a VLAN to each LAN port. In this case what is the sense for allowing more than one line entry at LAN interface ? Do the LAN interfaces act as a normal switch or not?
