Whether pVLAN is supported in virtualization


pVLAN is supported in virtualization, but the constraints are as follows:
Using pVLAN can reduce VLAN usage. The master VLAN can be configured during system installation and the slave VLANs can be added gradually in subsequent phases.
pVLAN and VRRP are mutually exclusive. If pVLAN is used, VRRP cannot be configured on aggregation switches, and the switches must be stacked.

The USG500 does not support IPSec in virtual systems. However, IPSec services can be isolated using VPN instances.

Whether virtualization supports error tolerance
Currently, virtualization does not support error tolerance. Error tolerance requires double the resources, and scenarios that require zero service interruption seldom exist. Virtualization support HA, however, and the duration of its service interruptions is just the amount of time it takes to restart a VM, which meets the basic requirements for most error tolerance. (1) Error tolerance requires that the active and standby copies run together, resulting in high resource usage and costs. (2) Error tolerance can only be implemented on single-vCPU VMs. In most cases, virtual servers are configured with multiple vCPUs. Therefore, customers cannot benefit from this function. (3) The active and standby VM hardware CPUs must be the same, making deployment more difficult. (4) The mainstream virtualization vendors provide HA to achieve high availability of virtual servers.

Whether the USG6000 virtual firewall supports DHCP
The USG6000 virtual system supports configuring DHCP and DHCP relay but not DHCPv6 or DHCP Snooping. The configuration commands are the same as those for the root system. For details, see the DHCP chapter of the product documentation.
