ExtremeWare XOS 11.5 Command Reference Guide
1154
Segment Timer expiry action • Segment down—Specifies that if the controller or partner switch
detect a down segment, that segment stays down and a query is
not sent through the ring. The switch marks the segment status as
"Down."
• Send alert—Specifies that if the controller or partner switch detect
a down segment, that switch keeps the segment up and sends a
warning message to the log (default). The switch sends a trap alert
and sets the failed flag [F].
Segment Port (available with the
detail keyword or by specifying a
shared port)
The segment port is the other ring port of an EAPS domain that is not
the shared-port.
Status (available with the detail
keyword or by specifying a shared port)
• Up—There is connectivity to the neighboring EAPS shared-port via
this port.
• Down—There is a break in the path to the neighboring EAPS
shared-port via this port.
• Blocking-Up—The path is Up, but due to the "root blocker" being
in the Active state, this port is blocked to prevent a loop.
• Blocking-Down—The “root blocker” is in the Active State; however,
the path is Down. Because the path is Down, there is no need to
block the “root blocker” port to prevent a loop.
• [F]—The segment timer has expired but has not received an
explicit link-down notification. The port remains in the Up state,
with the timer expired flag set to True.
EAPS Domain (available with the
detail keyword or by specifying a
shared port)
The EAPS domain having the segment port as one of its ring ports.
Vlan-port count (available with the
detail keyword or by specifying a
shared port)
The total number of VLANs being protected under this segment port.
Adjacent Blocking Id (available with
the detail keyword or by specifying a
shared port)
• None—The neighbor on this port is not reporting a Controller in the
Blocking state.
• <Link-Id>—The neighbor on this port is a controller in the Blocking
state with a link ID of <Link-Id>.
Segment RB Id (available with the
detail keyword or by specifying a
shared port)
• None—The neighbor on this port is not aware of a "root blocker" in
the network.
• <RB-Id>—The neighbor on this port has determined that there is a
"root blocker" in the network with a link ID of <RB-Id>.
Vlan (available with the detail
keyword or by specifying a shared port)
Displays a list of VLANs protected by the segment port.
Virtual-port Status (available with the
detail keyword or by specifying a
shared port)
This information appears for the Controller, when it is in either the
Blocking or Preforwarding state.
• Active-Open—This VLAN or port is in the Forwarding state and has
connectivity to the neighboring EAPS shared port via this port.
• Open—This VLAN or port is in the Forwarding state but does not
have connectivity to the neighboring EAPS shared port via this port.
• Blocked—This VLAN or port is in the Blocking state to prevent a
loop in the network.
• Down—This port’s link is down.
• Active—At this moment, this VLAN or port is not being handled by
EAPS shared port. Rather, this VLAN or port is being handled by
the regular EAPS protocol.
