Do Extreme Networks Switch Engine EXOS devices support virtualization?

Yes, they support Virtual Routers (VRs). There are three default ones known as VR-Mgmt, VR-Control and VR-Default.

VRs allow the switch to be segmented into different forwarding planes with each VR having its own routing table.

To create a new VR called blue:

create vr “blue”

To add all ports on slot 3 to VR blue:

configure vlan default delete ports 3:*
configure vr vr-default delete ports 3:*
configure vr blue add ports 3:*

After a user VR is created, the ports are added, and support for any required routing protocols is added, you can configure the VR.

To create a VLAN (Virtual LAN) in a VR, use the command:
create vlan vlan_name {description vlan-description} {vr name}
