Dell EMC SmartFabric OS10 User Guide Release 10.5.0

Sample configurations of UFD on VLT

The following examples show some of the uplink-state groups on VLT.

In the following illustration, both the upstream and downstream members are part of VLT port-channels. The uplink-state group includes both the VLT port-channels as members.

In the following example, the upstream member is part of VLT port-channel and the downstream member is an orphan port. The uplink-state group includes the VLT port-channel, VLT node, and the downstream port. The configuration is symmetric on both the VLT nodes.

In the following example, the downstream member is part of VLT port-channel and the upstream member is an orphan port. The uplink-state group includes the VLT port-channel, VLT node, and the upstream port. The configuration is symmetric on both the VLT nodes.

OS10 does not support adding a VLTi link member to the uplink-state group. You can add the VLTi link as upstream member to an uplink-state group using the upstream VLTi command. If the VLTi link is not available in the system, OS10 allows adding the VLTi link as an upstream member. In this case, UFD starts tracking the operational status of the VLTi link when the link is available. Until the VLTi link is available, the show uplink-state-group details command displays the status of the link as NA.

In the following example, both the VLT port-channel connected to the switch and the VLTi Link are upstream members. The VLT port-channel connected to the server is a downstream member. The UFD tracks the operational status of the peer port-channel.
