Profiles

An uplink profile is a template that defines how an NSX-managed Virtual Distributed Switch (N-VDS) connects to the physical network.

An uplink profile specifies:

  • The format of the uplinks of an N-VDS
  • The default teaming policy that is applied to those uplinks
  • The transport VLAN used for overlay traffic (if relevant)
  • The MTU of the uplinks
  • The network I/O control profile

The VMware NSX-T Data Center for VxBlock System design includes two uplink profiles:

Profile Description
Edge-9ka-uplink This uplink profile carries north-south traffic to the Cisco Nexus 9000 Series 9K-A ToR switch. This profile has one uplink port that is assigned with an MTU of 9000. No VLAN is attached to this profile because tagging of this VLAN occurs at the port group of the DVS where the edge node is connected.
Edge-9kb-uplink This uplink profile carries north-south traffic to the 9K-B ToR switch. This profile has one uplink port that is assigned with an MTU of 9000. No VLAN is attached to this profile because tagging of this VLAN occurs at the port group of the DVS where the edge node is connected.

For the compute workload environment, the VMware NSX-T Data Center for VxBlock System design includes the following profiles to connect workloads to the VMware NSX-T Data Center domain:

Profile Description
nsx-edge-tep-profile This profile defines the overlay network VLAN (121) the teaming policy (failover order) and uplink port (uplink-1) for which the workload traffic is routed. This profile also assigns the host/vm an overlay IP address based on the TEP pool for East-West traffic in the VMware NSX-T Data Center domain. The centralized Service Port Feature requires tagging to happen at the N-VDS. Trunk (not tag) in the VDS for the transport VLAN (121) on the edge nodes. The design, set the VLAN Type in the vcesys_nsx_transport port group to VLAN Trunking. Also, in the VMware NSX-T Data Center Manager, the design defines VLAN 121 in the uplink profile for nsx-edge-tep.
nsx-compute-transport The transport hosts use this profile to connect to the VMware NSX-T Data Center domain using the following:
  • Teaming policy (load balance source)
  • Uplink ports (uplink-1,uplink-2)
  • VLAN 121, which carries the transport host traffic
