Dell EMC SmartFabric OS10 User Guide Release 10.5.0

Restrictions

• VLANs 4001 to 4020 are reserved for internal switch communication and cannot be assigned to an interface.
• 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.
• On an MX7116n Fabric Expander, the two QSFP28-DD uplink interfaces operate only in Ethernet mode. Use the leftmost QSFP28-DD port 1 on the Fabric Expander to connect to servers with dual-port network interface cards (NICs). Do not use the rightmost QSFP28-DD port 2; it is reserved for future use to connect to servers with quad-port NICs.
