Dell EMC SmartFabric OS10 User Guide Release 10.5.0

VLAN scale profile

When you scale the number of VLANs on a switch, use the VLAN scale profile. VLAN scale profile consumes less memory. Enable the scale profile before you configure VLANs on the switch. The scale profile globally applies L2 mode on all VLANs you create and disables L3 transmission. To enable L3 routing traffic on a VLAN, use the mode L3 command.

1. Configure the L2 VLAN scale profile in CONFIGURATION mode.

   scale-profile vlan

2. (Optional) Enable L3 routing on a VLAN in INTERFACE VLAN mode.

   mode L3

After you configure the VLAN scale profile and enable L3 routing on the respective VLANs, save the configuration and reload the switch for the scale profile settings to take effect. To reload the switch, use reload command.

OS10(config)# scale-profile vlan
OS10(config)# interface vlan 10
OS10(conf-if-vl-10)# mode L3
OS10(conf-if-vl-10)# end
OS10# write memory
OS10(config)# reload

Dell EMC recommends the following sequence when configuring scale profile VLANs:

1. Enable the scale profile VLANs using scale-profile vlan command.
2. Disable IGMP and MLDP.

   For more information about disabling IGMP and MLD, see Internet Group Management Protocol and Multicast Listener Discovery Protocol.

3. Configure the Spanning-Tree mode to RSTP.
4. Configure the VLANs.
5. Enter Ethernet Interface mode and add the VLANs to the interface.
   NOTE Do not use interface range command to enter Ethernet Interface mode.
