9.2.1 Forwarding Tagged and Untagged Frames
Each port on the OLT is capable of passing tagged or untagged frames. To forward a frame from an
802.1Q VLAN-aware switch to an 802.1Q VLAN-unaware switch, the OLT first decides where to
forward the frame and then strips off the VLAN tag. To forward a frame from an 802.1Q VLAN-
unaware switch to an 802.1Q VLAN-aware switch, the OLT first decides where to forward the frame,
and then inserts a VLAN tag reflecting the ingress port's default VID. The default PVID is VLAN 1 for
all ports, but this can be changed.
A broadcast frame (or a multicast frame for a multicast group that is known by the system) is
duplicated only on ports that are members of the VID (except the ingress port itself), thus confining
the broadcast to a specific domain.
9.3 Static VLAN
Use a static VLAN to decide whether an incoming frame on a port should be
sent to a VLAN group as normal depending on its VLAN tag.
sent to a group whether it has a VLAN tag or not.
blocked from a VLAN group regardless of its VLAN tag.
You can also tag all outgoing frames (that were previously untagged) from a port with the specified
VID.
9.4 VLAN Configuration Overview
1 Use the vlan <vlan-id> command to configure or create a VLAN on the OLT. The OLT
automatically enters config-vlan mode. Use the exit command when you are finished configuring
the VLAN.
2 Use the interface port-channel <aid> command to set the VLAN settings on a port. The OLT
automatically enters config-interface mode. Use the pvid <vlan-id> command to set the VLAN ID
you created for the port-list in the PVID table. Use the exit command when you are finished
configuring the ports.
Note: See Section 7.6 on page 72 for interface port-channel commands.
