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 S t at us
Admin Status—Disp lays the d esired op er ationa l st at us of t his tun ne l. Possibl e values a re u p read y t o
pass packets, down, or testing in some test mode.
Operational Status—Indic ates th e actual operatio nal status of this tunne l, which is typical ly but not
limited to, a fu nc tio n of the state of individual segment s of thi s tunn el . Possi ble values ar e: up re a dy to
pass pac kets, down, testi ng in some t est mode , unknown st atu s ca nno t be det erm ined , dor mant ,
notPresent some component is missing or lowerLayerDown down due to the state of lower layer
interfaces.
Total Up Time—This va lue represen ts the aggre gate up time for all instances of thi s tunnel, if a v ail able.
If this value is unavailable, it must return a value of 0.
Primary Time Up—Specifies th e total time the primary instance of this tunnel has been active.
Advanced
Setup Priority—Displays the setu p prior ity of this tunn el. Possib le values are 0 thro ugh 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 violat ion of the e xplicit routing of this tunnel. When a fault is de tected on an adja cent do wnstream
link or node, a transit router can reroute traffic for fast service restoration.
•mergingPermitted—This flag permits transit r outers to mer ge this session with other RSVP sessions
for the pur pose of reduc ing resourc e overhead on downstream transit routers, there by providing
better network scalability.
•isPersistent—Indicates whether this tunnel should be restored automatically after a failure occurs.
•isPinned—This flag indi cat es wh ethe r t he loo se- r oute d hops of t his t unn el a re to b e pi nned.
•isComputed—This fl ag indica tes whet her the tunnel pa th is comp uted using a co nstraint -based
routing al gorit hm based on the mp lsTu nnelH opTable entries.
•recordRoute—T hi s fl ag indi cat es wh et her or n ot th e s ignal ing p rot oc ol shou ld r ememb er t he tun nel
path after it has been signaled.
Owner—Indicates wh ich p rot o col cre at ed and i s re spo nsible for ma nagi ng th is tunne l. Va lues r svp an d
crldp shou ld not be used at the head -end of a MPLS tunnel. Possible values are : admin repr esents all
management entities, rsvp, crldp, policyAgent, or other.
Local Pr otect In Us e—Displays that the local repai r mechanism is in use t o maintain this tunne l (usually
in the face of an outage of the link it was previously routed over).
Path Ch ang es—D isplays th e number of times the pa ths has chan ged for this tunnel.
Last Path C ha nge—Displays the time since the last path change for this tunnel.
State Transitions—Displa ys the numbe r of time s the state of this tunn el instan ce has ch anged.
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.
