Does the Cat 3850 support sub interface? As I do not want to use trunking.
NY-Switch(config)#interface tenGigabitEthernet 1/1/1.30 ?
% Unrecognized command

Hi
Sub-interfaces are supported on firewall and routers. Now you can use VLAN/SVI through a trunk in order to create Layer 3 connectivity.

Hello,
unfortunately, it doesn't. Here is an excerpt from the link below:
The switch does not support Layer 3 trunks; you cannot configure subinterfaces or use the encapsulation keyword on Layer 3 interfaces. The switch does support Layer 2 trunks and Layer 3 VLAN interfaces, which provide equivalent capabilities.

Hi,
Are you able to use traffic-shaping for the vlan interface if using this as a layer 3 transit connection between two endpoints?
We have a situation were we need to enable traffic-shaping over a layer 2 trunk as we need to maintain separate routing tables (VRFs). Not sure of another way I can shape the traffic over the trunk if I can't use this in an SVI?
Thanks
