XG replacing Cisco vlan trunking router on stick

onward

Could anyone explain how to translate this working example config from IOS 15.x Cisco router interface to SFOS 17.0.6 MR-6 XG interface that will be replacing it for performing inter-vlan routing from an Avaya switch?  I'm able to create the vlan sub interfaces in XG following How to Configure Virtual LAN but don't see any option for specifying native vlan or to configure vlan1 on a sub-interface and won't have matching equipment available for testing before deployment.  Thanks

    The Native VLAN (What Cisco calls it) or the Default VLAN on XG is set to 1 by default and can't be changed AFAIK (CMIIW). You might notice this when you create a new VLAN interface. The available vlan ID is limited to 2-4094.

    In your case, you would have to change the native vlan on your switch to 1 so that it can talk to the XG regarding untagged traffic.

    The IP that is set on the physical interface is the untagged/Default/Native Vlan 1. To create tagged VLAN, you need to 'Add VLAN' for each VLAN you need. You have to make sure that the VLAN is attached to the same physical interface that you configured for your untagged traffic.
