### Index (ciiSysLevelIndex)

Indicates the level that this entry describes.

### LSP Buffer Size (ciiSysLevelOrigLSPBuffSize)

The maximum size of LSPs and SNPs generated by this Intermediate System (IS) at this level.

### Interval (ciiSysLevelMinLSPGenInt)

Minimum time interval, in seconds, between the successive generation of LSPs with the same LSPID at this level by this IS.

### Overload State (ciiSysLevelOverloadState)

The overload state configured for the database at this level. The value overloaded indicates that a database is low on an essential resource, such as memory. The administrator may indirectly force the overload state to waiting while the router is initializing by setting a value for ciiSysLevelSetOverload. If this object is in either the waiting or overloaded state, LSPs are originated with the overload bit set.

### Set Overload Bit (ciiSysLevelSetOverload)

Overload bit set for the level.

The overload bit will continue to be set if the implementation runs out of memory, independent of this variable.

### Set Overload Until (ciiSysLevelSetOverloadUntil)

When this object is set, the overload bit should also be set and cleared when the value of sysUpTime exceeds the value of this object.

### Metric Style (ciiSysLevelMetricStyle)

Metric type used when LSPs are generated at this level.

### SPF Computation Style (ciiSysLevelSPFConsiders)

Metric type used when SPF computations are made at this level.

### Traffic Engineering (ciiSysLevelTEEnabled)

Indicates whether traffic engineering is enabled at this level.
