[c-nsp] vlan tagging question

If the device is incapable of understanding IEEE 802.1Q then it will not
be able to recognize and interpret the tagged frames, and will only
understand the native/untagged vlans.  It should only be communicating
on the native vlan.

Subject: [c-nsp] vlan tagging question

I have a non-cisco access device connecting to a cisco 3750 via gigE.
The 3750 interface is set for 802.1q trunking with two vlans - 100 and
201.  Vlan 201 is the native vlan on the cisco interface.  Should the
access device be tagging packets on vlan 201 or leaving them untagged?
