Description
The FORWARDING parameter is only applicable
when the VLAN is in UPSTREAMONLY forwarding
(UFO) mode. The interface's role for VLAN can
be:
PRIMARYUPSTREAM - all frames that are received
on the other interfaces will be sent out this inter-
face.
SECONDARYUPSTREAM - all frames that are
received on the other interfaces will be sent out
this interface if there is a fault with the PRIMA-
RYUPSTREAM.
DOWNSTREAM - Only frames that are received
over the UPSTREAM interface may be switched to
the DOWNSTREAM interface.
STP - The Spanning Tree Protocol will dynamically
determine the upstream interface.
UCP - For the specified VLANs the UCP protocol
will determine the UPSTREAM interface dynami-
cally.
EPSR - The VLAN(s) are part of an EPSR configura-
tion and the EPSR protocol determines the
UPSTREAM interface.
