Deployment Guide

Information contained in the tag header allows the system to prioritize trac and to forward information to ports associated with a specic
VLAN ID. Tagged interfaces can belong to multiple VLANs, while untagged interfaces can belong only to one VLAN.
Conguring VLAN Membership
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 recongure VLANs only on server-facing interfaces (1–8) so that an interface has membership only in specied VLANs.
To assign an Aggregator interface in Layer 2 mode to a specied 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 recongure an interface as a member of only specied 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 species a tagged VLAN number. Range: 2-4094.
INTERFACE mode
vlan tagged {vlan-id }
To recongure an interface as a member of only specied 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 species an untagged VLAN number. Range:
2-4094.
INTERFACE mode
vlan untagged {vlan-id}
If you congure additional VLAN membership and save it to the startup conguration, the new VLAN conguration takes place immediately.
Dell Networking OS Behavior: When two or more server-facing ports with VLAN membership are congured in a LAG based on the NIC
teaming conguration in connected servers learned via LACP, the resulting LAG is a tagged member of all the congured 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.
Displaying VLAN Membership
To view the congured VLANs, enter the show vlan command in EXEC privilege mode:
Dell#show vlan
