V-Net

V-Net is a virtual networking service that provide a Layer-2 (unrouted) or Layer-3 (routed) virtual network segments on switch ports anywhere on the switch fabric. V-NETs can be created and managed by a single tenant (single team) or they can be created and managed collaboratively by multiple tenants (different teams inside and/or outside the organization). Netris automatically configures a VXLAN with an EVPN control plane over an unnumbered BGP Layer-3 underlay network and organize the high availability for the default gateway behind the scenes.

V-Net Fields

  • Name - Unique name for the V-Net

  • Owner - Tenant, who can make any changes to current V-Net

  • V-Net state - Active/Disable state for entire V-Net

  • VLAN aware - Enable VLAN aware bridge, use only in rare cases, if otherwise is not possible

  • Guest tenants - List of tenants allowed to add/edit/remove ports to the V-Net but not manage other parameters

  • Sites - Ports from these sites will be allowed to participate in the V-Net. (Multi-site circuits would require backbone connectivity between sites).

  • IPv4 Gateway - IPv4 address to be used as a default gateway in this V-Net. Should be configured under Net→IPAM as an assignment, assigned to the owner tenant, and available in the site where V-Net is intended to span.

  • IPv6 Gateway - IPv6 address to be used as a default gateway in this V-Net. Should be configured under Net→IPAM as an assignment, assigned to the owner tenant, and available in the site or sites where V-Net is intended to span.

  • Port - Physical Switch Port anywhere on the network. Switch Port should be assigned to the owner or guest tenant under Net→Switch Ports.

    • Enabled - Enable or disable individual Switch Port under current V-Net

    • Port Name - Switch Port format: <alias>(swp<number>)@<switch name>

    • VLAN ID / Untag - Specify a VLAN ID for tagging traffic on a per-port basis or set Untag not to use tagging on a particular port. VLAN tags are only significant on each port’s ingress/egress unless VLAN aware mode is used.

    • LAG Mode - Allows for active-standby dual-homing, assuming LAG configuration on the remote end. Active/active dual homing will be enabled in future releases (dependence on SVI support by NOSes).

Tip

Many switches can’t autodetect old 1Gbps ports. If attaching hosts with 1Gbps ports to 10Gpbs switch ports, you’ll need to change the speed for a given Switch Port from Auto(default) to 1Gbps. You can edit a port in Net→Switch Ports individually or in bulk.
