Unable to create subinterfaces on C9200L

[mansab.mahmood]

Hello everyone, 

Im trying to create subinterfaces on a routed interface in a C9200L however I'm unable to do this. 

The configuration guide is contradicting where at one place it mentions that subinterfaces are not supported and at a second point it states that sub interfaces are supported. 

Reference guide

Appreciate your support 

MM.

Hi,

I don't think you can configure subinterface on the 9200 series. You can  just use SVIs instead of subinterfaces.

The device does not support Layer 3 trunks; you cannot configure subinterfaces or use the encapsulation keyword on Layer 3 interfaces. The device does support Layer 2 trunks and Layer 3 VLAN interfaces, which provide equivalent capabilities.
