VLAN scale prole
When you scale the number of VLANs on a switch, use the VLAN scale prole. This consumes less memory. Enable the scale prole before
you congure VLANs on the switch. The scale prole globally applies L2 mode on all VLANs you create and disables L3 transmission. To
enable L3 routing trac on a VLAN, use the mode L3 command.
1 Congure the L2 VLAN scale prole in CONFIGURATION mode.
scale-profile vlan
2 (Optional) Enable L3 routing on a VLAN in INTERFACE VLAN mode.
mode L3
After you upgrade OS10 from an earlier version with congured VLANs, if you congure the VLAN scale prole and enable L3 routing on
VLANs, save the conguration and use the reload command to apply the scale prole settings.

OS10(config)# interface vlan 10
OS10(conf-if-vl-10)# mode L3
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 aected 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 congure 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.

• Enter the Loopback interface number to view the conguration in EXEC mode.

• Enter the Loopback interface number to delete a Loopback interface in CONFIGURATION mode.
