The following information appears:

Index (ciiCircIndex)

If Index (ciiCircIfIndex)

Specifier (ciiCircIfSubIndex)

Admin State (ciiCircAdminState)

Type (ciiCircType)

External Domain (ciiCircExtDomain)

Level (ciiCircLevel)

Passive Circuit (ciiCircPassiveCircuit)

Mesh Group Enabled (ciiCircMeshGroupEnabled)

Mesh Group (ciiCircMeshGroup)

Small Hellos (ciiCircSmallHellos)

Last Up Time (ciiCircLastUpTime)

3Way Handshake (ciiCirc3WayEnabled)

Extended ID (ciiCircExtendedCircID)


Index (ciiCircIndex)

The identifier of this circuit, unique within the Intermediate System (IS). This object is used for SNMP indexing purposes only and does not need to correspond to any protocol value.


If Index (ciiCircIfIndex)

Value of ifIndex for the interface to which this circuit corresponds. This object cannot be modified after creation


Specifier (ciiCircIfSubIndex)

A specifier for the part of the interface ifIndex to which this circuit corresponds, such as a DLCI or VPI/VCI. This object cannot be modified after creation


Admin State (ciiCircAdminState)

Administrative state of the circuit.


Type (ciiCircType)

Indicates the circuit type. The type specified must be compatible with the interface type defined by ciiCircIfIndex.

There are five possible values:

broadcast(1)

ptToPt(2)

staticIn(3)

staticOut(4)

dA(5)


External Domain (ciiCircExtDomain)

When this object is set to true, the normal transmission and interpretation of Intra-domain IS-IS PDUs on this circuit are suppressed.


Level (ciiCircLevel)

Indicates which type of packets will be sent and accepted on this circuit. The values used will be modified by the settings configured for ciiSysType.

There are three available values:

level1(1)

level2(2)

level1L2(3)


Passive Circuit (ciiCircPassiveCircuit)

When set to true, this interface is included in LSPs, even if it is not running the IS-IS protocol.


Mesh Group Enabled (ciiCircMeshGroupEnabled)

Indicates whether this port is a member of a mesh group. There are three possible values:

inactive(1)

blocked(2)

set(3)


Mesh Group (ciiCircMeshGroup)

Circuits in the same mesh group act as a virtual multiaccess network. LSPs seen on one circuit in a mesh group will not be flooded to another circuit in the same mesh group. If ciiCircMeshGroupEnabled is inactive or blocked, the value of this object is ignored.


Small Hellos (ciiCircSmallHellos)

Indicates whether unpadded Hellos can be sent on LAN circuits. When the value of this object is false, LAN Hellos must be padded.


Last Up Time (ciiCircLastUpTime)

When the circuit is enabled, this object is the value of sysUpTime when ciiCircAdminState last entered the on state. When the circuit is not enabled, then this object is the value of sysUpTime when the circuit last entered the on state. A value of zero indicates that the circuit has never been in the on state.


3Way Handshake (ciiCirc3WayEnabled)

Indicates whether this circuit is enabled to run a 3-way handshake.


Extended ID (ciiCircExtendedCircID)

Value to be used as the extended circuit ID in a 3-way handshake. This value is used only if the value of ciiCirc3WayEnabled is true. In addition, it must be unique across all circuits on this IS.
