Dell PowerEdge FN I/O Module Configuration Guide 9.10(0.0)

By default, all Aggregator ports are member of all (4094) VLANs, including the default untagged VLAN 1. You can use the CLI or CMC interface to reconfigure VLANs only on server-facing interfaces (1–8) so that an interface has membership only in specified VLANs.

To assign an Aggregator interface in Layer 2 mode to a specified group of VLANs, use the vlan tagged and vlan untagged commands. To view which interfaces are tagged or untagged and to which VLAN they belong, use the show vlan command (Displaying VLAN Membership).

To reconfigure an interface as a member of only specified tagged VLANs, enter the vlan tagged command in INTERFACE mode:

1. Add the interface as a tagged member of one or more VLANs, where: vlan-id specifies a tagged VLAN number. Range: 2-4094.

   INTERFACE mode

   vlan tagged { vlan-id }

To reconfigure an interface as a member of only specified untagged VLANs, enter the vlan untagged command in INTERFACE mode:

1. Add the interface as an untagged member of one or more VLANs, where: vlan-id specifies an untagged VLAN number. Range: 2-4094.

   INTERFACE mode

   vlan untagged { vlan-id}

If you configure additional VLAN membership and save it to the startup configuration, the new VLAN configuration takes place immediately.

Dell Networking OS Behavior: When two or more server-facing ports with VLAN membership are configured in a LAG based on the NIC teaming configuration in connected servers learned via LACP, the resulting LAG is a tagged member of all the configured VLANs and an untagged member of the VLAN to which the port with the lowest port ID belongs. For example, if port 0/3 is an untagged member of VLAN 2 and port 0/4 is an untagged member of VLAN 3, the resulting LAG consisting of the two ports is an untagged member of VLAN 2 and a tagged member of VLAN 3.
