An uplink is a link from the NSX Edge nodes to the top-of-rack switches or NSX-T Data Center logical switches. A link is from a physical network interface on an NSX Edge node to a switch.
An uplink profile defines policies for the uplinks. The settings defined by uplink profiles can include teaming policies, active and standby links, transport VLAN ID, and MTU setting.
Configuring uplinks for VM appliance-based NSX Edge nodes and Host Transport nodes:- If the Failover teaming policy is configured for an uplink profile, then you can only configure a single active uplink in the teaming policy. Standby uplinks are not supported and must not be configured in the failover teaming policy. When you install NSX Edge as a virtual appliance or host transport node, use the default uplink profile.
- If the Load Balanced Source teaming policy is configured for an uplink profile, then you can configure multiple active uplinks on the same N-VDS. Each uplink is associated with one physical NIC with a distinct name and IP address. The IP address assigned to an uplink endpoint is configurable using IP Assignment for the N-VDS.
You must use the Load Balanced Source teaming policy for traffic load balancing.
Prerequisites
- See NSX Edge network requirements in NSX Edge Installation Requirements.
- Each uplink in the uplink profile must correspond to an up and available physical link on your hypervisor host or on the NSX Edge node.
For example, your hypervisor host has two physical links that are up: vmnic0 and vmnic1. Suppose vmnic0 is used for management and storage networks, while vmnic1 is unused. This might mean that vmnic1 can be used as an NSX-T Data Center uplink, but vmnic0 cannot. To do link teaming, you must have two unused physical links available, such as vmnic1 and vmnic2.
For an NSX Edge, tunnel endpoint and VLAN uplinks can use the same physical link. For example, vmnic0/eth0/em0 might be used for your management network and vmnic1/eth1/em1 might be used for your fp-ethX links.
