Description
Displays the port number of the shared port.
Indicates whether the switch on either end of the common link is a
controller or partner. The mode is configured by the user.
The link ID is the unique common link identifier configured by the
user.
Displays one of the following:
• Yes—Indicates that the link ID and the mode are configured.
• No—Indicates that the link ID or the mode is not configured.
Displays one of the following states:
• Idle—Shared-port instance is not running.
• Ready—The EAPS shared-port instance is running, the neighbor
can be reached, and the common link is up.
• Blocking—The EAPS shared-port instance is running, the neighbor
cannot be reached, or the common link is down.
• Preforwarding—The EAPS shared-port instance is in a blocking
state, and the common link came up. To prevent a superloop, a
temporary blocking state is created before going into Ready state.
Indicates the number of EAPS domains sharing the common link.
Indicates the total number of VLANs that are protected under the
EAPS domains sharing this common link.
• Yes—Indicates that the EAPS instance on the other end of the
common link is configured with matching link ID and opposite
modes. For example, if one end of the common link is configured
as a controller, the other end must be configured as a partner.
• Err—Indicates that the EAPS instance on the other end of the
common link is configured with a matching link ID, but the modes
are configured the same. For example, both modes are configured
as controller, or both modes are configured as partner.
• No—The neighbor on the other end of the common link cannot be
reached. Indicates one or more of the following:
- The switch on the other end of the common link is not running.
- The shared port has not been created.
- The link IDs on each side of the common link do not match.
- The common link, and any other segment, between the controller
and partner are not fully connected.
• None—This EAPS shared-port is not the "root blocker."
• Active—This EAPS shared-port is the "root blocker" and is
currently active.
• Inactive—This EAPS shared-port is the "root blocker" but is
currently inactive.
The ID of the root blocker. If the value is none, there are not two or
more common-link failures.
• None—Indicates that there is no Active-Open port on the VLAN.
• Port #—Indicates the port that is Active-Open and is in a
forwarding state.
