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.
Apply VLAN scale profile
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.
Loopback interfaces
A Loopback interface is a virtual interface where the software emulates an interface. Because a Loopback interface is not
associated to physical hardware entities, the Loopback interface status is not affected by hardware status changes.
Packets routed to a Loopback interface process locally to the OS10 device. Because this interface is not a physical interface, to
provide protocol stability you can configure routing protocols on this interface. You can place Loopback interfaces in default L3
mode.
● Enter the Loopback interface number in CONFIGURATION mode, from 0 to 16383.
