DESCRIPTION
"This read-only variable displays the current
transmit state of the LAN port as follows:
'initializing': A transient state lasting a
few milliseconds after startup.
'on': A second transient state immediately
following initializing.
'pre-forwarding 1': The first half of the pre-
forwarding interval. Initial Spanning Tree
packets traverse the network and the root is
elected. No learning or forwarding takes place.
'pre-forwarding 2': The second half of the pre-
forwarding interval. The bridge listens to
packets on the network and learning begins, but
no forwarding takes place.
'forwarding': The normal Spanning Tree operating
state. The bridge forwards frames on this link
and learns from received frames.
'dls forwarding': The normal DLS operating
state. This link is treated as forwarding for
Spanning Tree calculations, but the link is
participating in VitalinkUs proprietary
Distributed Load Sharing (DLS) algorithm.
Certain user traffic can traverse the link.
'backup': Hot standby state. No bridged user
traffic is forwarded. The link transmits and
receives only certain network management frames
that determine if the port should remain in
backup or if it should transition to pre-
forwarding.
'dls backup': This link is treated as backup for
Spanning Tree calculations, but the link is
participating in VitalinkUs proprietary
Distributed Load Sharing algorithm. Certain user
traffic can traverse the link.
'off': Offline. No traffic may pass on this
link, and the line is not used for any internal
computations.
'disabled': The Disable switch (screen /2/n/2)
was on when the bridge was initialized. Only
certain network management frames are
transmitted. No user traffic is forwarded and no
learning takes place on this link.
'broken': Communication is not possible over
this link. Spanning Tree Protocol computations
consider broken links in order to calculate the
root priority."
