EAPS Shared Port Configuration Rules
The following rules apply to EAPS shared port configurations:
●
The controller and partner shared ports on either side of a common link must have the same
link ID.
●
Each common link in the network must have a unique link ID.
●
The modes on either side of a common link must be different from each other; one must be a
controller and one must be a partner .
●
There can be only up to two shared ports per switch.
●
There cannot be more than one controller on a switch.
Valid combinations on any one switch are:
■
1 controller
■
1 partner
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.
