You can use the CLI or CMC interface to reconfigure VLANs only on server-facing interfaces (1 to 32)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 andvlan untagged commands. To view which interfaces are tagged or untagged and to which VLAN theybelong, use the show vlan command (Displaying VLAN Membership).To reconfigure an interface as a member of only specified tagged VLANs, enter the vlan tagged commandin INTERFACE mode:To reconfigure an interface as a member of only specified untagged VLANs, enter the vlan untaggedcommand in INTERFACE mode:When you delete a VLAN (using the no vlan vlan-id command), any interfaces assigned to the VLAN areassigned to the default VLAN as untagged interfaces.If you configure additional VLAN membership and save it to the startup configuration, the new VLANconfiguration is activated following a system reboot.Command Syntax Command Mode Purposevlan tagged {vlan-id | vlan-range} INTERFACE Add the interface as a tagged member of one or moreVLANs, where:vlan-id specifies a tagged VLAN number. Range: 2-4094vlan-range specifies a range of tagged VLANs. SeparateVLAN IDs with a comma; specify a VLAN range with adash; for example, vlan tagged 3,5-7.Command Syntax Command Mode Purposevlan untagged {vlan-id | vlan-range} INTERFACE Add the interface as an untagged member of one or moreVLANs, where:vlan-id specifies an untagged VLAN number.Range: 2-4094vlan-range specifies a range of untagged VLANs.Separate VLAN IDs with a comma; specify a VLANrange with a dash; for example, vlan tagged 3,5-7.FTOS Behavior: When two or more server-facing ports with VLAN membership are configured in aLAG based on the NIC teaming configuration in connected servers learned via LACP, the resultingLAG is a tagged member of all the configured VLANs and an untagged member of the VLAN to whichthe 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 ofVLAN 3, the resulting LAG consisting of the two ports is an untagged member of VLAN 2 and a taggedmember of VLANs 2 and 3.
