Cisco Systems 12000/10700 V3.1.1 manual Tunnel Status, Advanced, 15-37

Chapter 15 MPLS Management

Fault Management for MPLS Traffic Engineering

Storage Type—This variable indicates the storage type for this object.

Creation Time—Specifies the value of SysUpTime when the first instance of this tunnel came into existence.

Tunnel Status

Admin Status—Displays the desired operational status of this tunnel. Possible values are up ready to pass packets, down, or testing in some test mode.

Operational Status—Indicates the actual operational status of this tunnel, which is typically but not limited to, a function of the state of individual segments of this tunnel. Possible values are: up ready to pass packets, down, testing in some test mode, unknown status cannot be determined, dormant, notPresent some component is missing or lowerLayerDown down due to the state of lower layer interfaces.

Total Up Time—This value represents the aggregate up time for all instances of this tunnel, if available. If this value is unavailable, it must return a value of 0.

Primary Time Up—Specifies the total time the primary instance of this tunnel has been active.

Advanced

Setup Priority—Displays the setup priority of this tunnel. Possible values are 0 through 7.

Holding Priority—Displays the holding priority for this tunnel. Possible values are 0 through 7.

Session Attributes—This bitmask indicates optional session values for this tunnel. The following describes these bitfields:

•fastReroute—This flag indicates that the any tunnel hop may choose to reroute this tunnel without tearing it down. This flag permits transit routers to use a local repair mechanism which may result in violation of the explicit routing of this tunnel. When a fault is detected on an adjacent downstream link or node, a transit router can reroute traffic for fast service restoration.

•mergingPermitted—This flag permits transit routers to merge this session with other RSVP sessions for the purpose of reducing resource overhead on downstream transit routers, thereby providing better network scalability.

•isPersistent—Indicates whether this tunnel should be restored automatically after a failure occurs.

•isPinned—This flag indicates whether the loose- routed hops of this tunnel are to be pinned.

•isComputed—This flag indicates whether the tunnel path is computed using a constraint-based routing algorithm based on the mplsTunnelHopTable entries.

•recordRoute—This flag indicates whether or not the signaling protocol should remember the tunnel path after it has been signaled.

Owner—Indicates which protocol created and is responsible for managing this tunnel. Values rsvp and crldp should not be used at the head-end of a MPLS tunnel. Possible values are: admin represents all management entities, rsvp, crldp, policyAgent, or other.

Local Protect In Use—Displays that the local repair mechanism is in use to maintain this tunnel (usually in the face of an outage of the link it was previously routed over).

Path Changes—Displays the number of times the paths has changed for this tunnel.

Last Path Change—Displays the time since the last path change for this tunnel.

State Transitions—Displays the number of times the state of this tunnel instance has changed.

Include Any Affinity—A link satisfies the include-any constraint if and only if the constraint is zero, or the link and the constraint have a resource class in common.
