Dell MX9116n EMC SmartFabric OS10 User Guide - Page 456

In SmartFabric Services mode, you can configure up to a maximum of 256 uplink VLANs including the default VLAN given the limited hardware capability. For each of the uplink VLAN interface, the system creates an ACL entry to classify the traffic. This ACL entry maps the traffic from the VLAN to the corresponding traffic-class (TC) queue. If you create more than 256 VLANs, ACL table creation fails when the uplinks are created in the Fiber Channel Gateway or the Fiber Channel Direct Attach mode. In SmartFabric mode, although you can use the CLI to create VLANs 1 to 4000 and 4021 to 4094, you cannot assign interfaces to them. For this reason, do not use the CLI to create VLANs in SmartFabric mode. Segment a L2 network using VLANs to: • Minimize broadcast and multicast traffic in the L2 network • Increase security by isolating ports into different VLANs • Ease network management Default VLAN All interface ports are administratively up in L2 mode and are automatically placed in the default VLAN as untagged interfaces. When you assign a port to a non-default VLAN in Trunk mode, the interface remains an untagged member of the default VLAN and a tagged member of the new VLAN. When you assign a port to a non-default VLAN in Access mode, it removes from the default VLAN and is assigned to the new VLAN as an untagged member of the new VLAN. • VLAN 1 is the default VLAN. • You cannot delete the default VLAN. However, you can change the default VLAN ID number using the default vlan-id command. Use the show vlan command to verify that the interface is part of the default VLAN (VLAN 1).

You can add an Ethernet interface as a trunk port or as an access port, but it cannot be added as both at the same time.
