REVISION "9610280000Z" DESCRIPTION "Initial version of this MIB module." ::= { ciscoMgmt 65 } -- assigned by cana@cisco.com ciscoPnniMIBObjects OBJECT IDENTIFIER ::= { ciscoPnniMIB 1 } E164Address ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "A native E.164 address, encoded in BCD format. An address of length zero indicates that no address is specified." SYNTAX OCTET STRING (SIZE(0|8)) -- The Base Group (per switching system objects) ciscoPnniBase OBJECT IDENTIFIER ::= { ciscoPnniMIBObjects 1 } ciscoPnniBackgroundRoutes OBJECT-TYPE SYNTAX TruthValue MAX-ACCESS read-write STATUS current DESCRIPTION "Specifies whether background route computation is enabled on this switching system. In this mode, multiple background trees are precomputed for several service categories and QoS metrics. If no route is found in the background trees that satisfies the QoS requirements of a particular setup request, route selection reverts to on-demand computation. When the value of this object is `false', only on-demand route computation is used (i.e., a separate route computation is performed for each SETUP or ADD PARTY message received over a UNI or IISP interface, or for which this node is a PNNI entry border node). It is recommended that background route computation be enabled in large networks, due to better scalability in terms of processing requirements." DEFVAL { false } ::= { ciscoPnniBase 1 } ciscoPnniBackgroundPollInterval OBJECT-TYPE SYNTAX INTEGER (1..60) UNITS "seconds" MAX-ACCESS read-write STATUS current DESCRIPTION "Specifies how often the switching system polls for a significant change that triggers new computation of the background routes. Increasing the value of this object causes the switching system to throttle background route computation." DEFVAL { 10 } ::= { ciscoPnniBase 2 } ciscoPnniBackgroundInsignificantThreshold OBJECT-TYPE SYNTAX INTEGER (1..100) UNITS "changes" MAX-ACCESS read-write STATUS current DESCRIPTION "Specifies the number of insignificant changes necessary to trigger a new computation of the background routes." DEFVAL { 32 } ::= { ciscoPnniBase 3 } ciscoPnniResourceMgmtPollInterval OBJECT-TYPE SYNTAX INTEGER (1..60) UNITS "seconds" MAX-ACCESS read-write STATUS current DESCRIPTION "Specifies how often PNNI polls resource management to update the values of local interface metrics and attributes. The value of this object impacts the number of new instances of PTSEs originated by this switching system. A larger interval reduces the number of new instances of PTSEs caused by interface traffic fluctuation. A smaller interval allows PNNI to track traffic fluctuations more quickly, at the expense of increased processing load. In normal situations, this object should not be changed from its default value. Care should be taken when adjusting this parameter so as not to overload switch processing." DEFVAL { 5 } ::= { ciscoPnniBase 4 } ciscoPnniAdminWeightMode OBJECT-TYPE SYNTAX INTEGER { uniform(1), linespeed(2) } MAX-ACCESS read-write STATUS current DESCRIPTION "Specifies the mode of default administrative weight assignment for PNNI interfaces. When this value is set to `uniform', by default the administrative weight of each PNNI interface is set to 5040, as defined in the ATM Forum PNNI 1.0 Specification. When this value is set to `linespeed', by default the administrative weight is set based on the linespeed or maximum cell rate of the interface. In the absence of other constraints, the `uniform' mode causes PNNI routing to minimize the number of hops. Basing administrative weight on linespeed allows path selection to prefer paths along higher bandwidth interfaces." DEFVAL { uniform } ::= { ciscoPnniBase 5 } ciscoPnniMaxAdminWeightPercentage OBJECT-TYPE SYNTAX INTEGER (0 | 100..2000) MAX-ACCESS read-write STATUS current DESCRIPTION "Specifies the maximum acceptable administrative weight for alternate routes as a percentage factor of the least administrative weight of any route to the destination. The constraint on administrative weight only takes effect when background route computation is enabled. The constraint on administrative weight increases network efficiency under heavy loads by preventing alternate routes that use too many network resources from being specified. This constraint provides a generalized form of a hop count limit. The distinguished value zero indicates that there is no constraint on administrative weight for alternate routes. All other valid values are greater than or equal to 100 percent." DEFVAL { 0 } ::= { ciscoPnniBase 6 } ciscoPnniRouteOptimizationThreshold OBJECT-TYPE SYNTAX INTEGER (5..100) UNITS "percent" MAX-ACCESS read-write STATUS current DESCRIPTION "Specifies the percentage reduction in the administrative weight of the existing path required to trigger route optimization. When route optimization is enabled and the threshold is exceeded, the existing path is partially torn down and a new path is established."

Automatically generated summary addresses can only be removed by setting this object to `false'. They cannot be removed through the pnniSummaryTable in the ATM Forum PNNI MIB. For lowest-level nodes with auto-summary enabled, each switching system generates one or more 13-byte summary address prefixes based on the switch address(es).

DEFVAL { true } ::= { ciscoPnniNodeEntry 1 } ciscoPnniNodeRedistributeStatic OBJECT-TYPE SYNTAX TruthValue MAX-ACCESS read-create STATUS current DESCRIPTION "Specifies whether redistribution of ATM static routes to the PNNI routing domain is enabled.

DEFVAL { true } ::= { ciscoPnniNodeEntry 2 } ciscoPnniNodePtseRequest OBJECT-TYPE SYNTAX INTEGER(1..1000) MAX-ACCESS read-create STATUS current DESCRIPTION "Specifies the maximum number of PTSEs that can be requested in one PTSE request packet." DEFVAL { 32 } ::= { ciscoPnniNodeEntry 3 } ciscoPnniNodeName OBJECT-TYPE SYNTAX DisplayString MAX-ACCESS read-create STATUS current DESCRIPTION "Specifies the textual name of the PNNI node.

This allows all cisco PNNI nodes to use this node name to identify this PNNI node. The default value of the node name is the value of the switching system's host name." ::= { ciscoPnniNodeEntry 4 } ciscoPnniNodeScopeMappingMode OBJECT-TYPE SYNTAX INTEGER { automatic(1), manual(2) } MAX-ACCESS read-create STATUS current DESCRIPTION "Specifies the configuration mode of the mapping from organizational scope values (used at UNI interfaces) to PNNI scope (i.e., in terms of PNNI routing level indicators). In `automatic' mode, for each organizational scope value the corresponding PNNI level is the minimum of the ATM Forum PNNI 1.0 default value (see Section 5.3.6 of PNNI 1.0) and the level l of this node: org scope ATM Forum default level auto mode level 1-3 96 min(l,96) 4-5 80 min(l,80) 6-7 72 min(l,72) 8-10 64 min(l,64) 11-12 48 min(l,48) 13-14 32 min(l,32) 15(global) 0 0 Use of the `automatic' mode ensures that all organizational scope values cover an area at least as wide as this node's peer group. When this object is written with the value `automatic', objects in the pnniScopeMappingEntry for this node are overwritten. These objects cannot be modified while this object is set to `automatic'. When this object is written with the value `manual', the objects in the pnniScopeMappingEntry for this node are allowed to be modified."

Link selection applies whenever the port specified in the Designated Transit List (DTL) is zero and there are multiple interfaces to the next node. Valid values are: adminWeightMinimize - transmits call on the interface with the lowest administrative weight, blockingMinimize - Minimizes subsequent call blocking, transmitSpeedMaximize - Transmits call on highest speed parallel link, loadBalance - Balances calls across all parallel links. When multiple parallel links are configured inconsistently, the order of precedence of configured values is `adminWeightMinimize', `blockingMinimize', `transmitSpeedMaximize', and then `loadBalance'; i.e., if any of the links is configured as adminWeightMinimize, that is used for the entire link group. For Best Effort call setups (UBR or ABR), load balancing is always used."
