One of the key requirements to configure the transport nodes is to attach the default or custom Uplink Profile.
The uplink profile is a template that defines how an N-VDS connects to the physical network. It specifies:
- Format of the uplinks of an N-VDS [Active/Standby links]
- Teaming policy applied to those uplinks
- transport VLAN used for overlay traffic
- MTU of the uplinks
Uplink profiles allow you to consistently configure identical capabilities for network adapters across multiple hosts or nodes.
Create custom Uplink Profile:
- From a browser, log in with admin privileges to an NSX Manager
- Select Fabric > Profiles > Uplink Profiles and click Add.
- Name: <Enter an uplink profile name>
- Description: <Add an optional uplink profile description>
- Teaming Policy: The teaming policy defines how the hostswitch uses its uplink for redundancy and traffic load balancing. There are two types of NIC teaming policies:
- Failover Order:
- An active uplink is specified along with an optional list of standby uplinks.
- If the active uplink fails, the next uplink in the standby list replaces the active uplink.
- Can be used on ESXi & KVM hosts
- There is no load balancing between the physical network adapters
- Load Balanced Source:
- A list of active uplinks is specified, and each interface on the transport node is pinned to one active uplink.
- Uses all of the active uplinks
- This policy is not supported for the KVM hosts.
- Failover Order:
- LAGS: (Optional) Link aggregation groups (LAGs) using Link Aggregation Control Protocol (LACP) for the transport network.
- Note For LACP, multiple LAG is not supported on KVM hosts.
- Active Uplinks: Add a comma-separated list of active uplink names. The active and standby uplink names you create can be any text to represent physical links.
- Standby Uplinks: Add a comma-separated list of standby uplink names.
- MTU: The default value is 1600.
- Click SAVE
Custom Uplink profile:
The NSX-T edges does not support Standby Uplinks.
