### Neighbor ID (ciiISAdjNeighSysID)

System ID of the neighboring Intermediate System (IS).

### Neighbor SNPA Address (ciiISAdjNeighSNPAAddress)

SNPA address of the neighboring system.

### Neighbor Type (ciiISAdjNeighSysType)

Indicates what type of neighboring system this is.

### Nbr Extended Circ ID (ciiISAdjNbrExtendedCircID)

The four byte extended circuit ID learned from the neighboring system during a 3-way handshake.

### Usage (ciiISAdjUsage)

Indicates the usage level of this adjacency. There are three possible values:

> level1(1)

> level2(2)

> level1and2(3)

### State (ciiISAdjState)

The state of the adjacency. There are four possible values:

> down(1)

> initializing(2)

> up(3)

> failed(4)

### 3Way State (ciiISAdj3WayState)

The 3-way state of the adjacency. There are four possible values:

> up(0)

> initializing(1)

> down(2)

> failed(3)

These values are picked to match the historical on-the-wire representation of the 3-way state and are not intended to match ciiISAdjState.

### Hold Timer (ciiISAdjHoldTimer)

Holding time, in seconds, for this adjacency. The value of this object is based on received IIH PDUs and the elapsed time since their receipt.

### Neighbor Priority (ciiISAdjNeighPriority)

Priority configured for the neighboring IS to become the designated IS.

### Last Up Time (ciiISAdjLastUpTime)

When the value of ciiISAdjState is up, this object is the value of sysUpTime when the adjacency last entered the up state. If the adjacency has never been in the up state, then the value of this object is zero.
