Term Definition
Options An integer value that indicates the optional OSPF capabilities supported by the neighbor. The
neighbor's optional OSPF capabilities are also listed in its Hello packets. This enables received
Hello Packets to be rejected (that is, neighbor relationships will not even start to form) if there is a
mismatch in certain crucial OSPF capabilities.
Router Priority The OSPF priority for the specified interface. The priority of an interface is a priority integer from 0 to
255. A value of 0 indicates that the router is not eligible to become the designated router on this
network.
Dead Timer Due The amount of time, in seconds, to wait before the router assumes the neighbor is unreachable.
Up Time Neighbor uptime; how long since the adjacency last reached the Full state.
State The state of the neighboring routers.
Events The number of times this neighbor relationship has changed state, or an error has occurred.
Retransmitted The number of LSAs retransmitted to this neighbor.
LSAs
Retransmission An integer representing the current length of the retransmission queue of the specified neighbor
Queue Length router Id of the specified interface.
Restart Helper Indicates the status of this router as a helper during a graceful restart of the router specified in the
Status command line:
• Helping—This router is acting as a helpful neighbor to this neighbor. A helpful neighbor does not
report an adjacency change during graceful restart, but continues to advertise the restarting
router as a FULL adjacency. A helpful neighbor continues to forward data packets to the
restarting router, trusting that the restarting router's forwarding table is maintained during the
restart.
• Not Helping—This router is not a helpful neighbor at this time.
Restart Reason When this router is in helpful neighbor mode, this indicates the reason for the restart as provided by
the restarting router:
• Unknown (0)
• Software restart (1)
• Software reload/upgrade (2)
• Switch to redundant control processor (3)
• Unrecognized - a value not defined in RFC 3623
When NETGEAR Managed Switch software sends a grace LSA, it sets the Restart Reason to
Software Restart on a planned warm restart (when the initiate failover command is
invoked), and to Unknown on an unplanned warm restart.
Remaining Grace The number of seconds remaining the in current graceful restart interval. This is displayed only when
Time this router is currently acting as a helpful neighbor for the router specified in the command.
Restart Helper Exit Indicates the reason that the specified router last exited a graceful restart.
Reason
• None—Graceful restart has not been attempted
• In Progress—Restart is in progress
• Completed—The previous graceful restart completed successfully
• Timed Out—The previous graceful restart timed out
• Topology Changed—The previous graceful restart terminated prematurely because of a
topology change
