### Description

```asn1
isisCircLevelIDOctet OBJECT-TYPE
SYNTAX Unsigned32(0..255)
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"A one-byte identifier for the circuit selected by the
Intermediate System.
On point-to-point circuits, the value is used as the Local
Circuit ID in point-to-point IIH PDUs transmitted on this
circuit. In this case, values of isisCircLevelIDOctet do
not need to be unique.
For broadcast circuits, the value is used to generate the
LAN ID that will be used if this Intermediate System is
elected as the Designated IS on this circuit. The value
is required to differ on LANs where the Intermediate System
is the Designated Intermediate System."
```

**Classification:** MIB object for network management
