Circuits
The circuits command shows the status of the dial circuits configured on the ISDN
interface that are in the state of “Up” or “Available”.
Syntax:
circuits
Example:
circuit
Net Interface MAC/Data-Link State Reason Duration
4 PPP/1 Point to Point Up B1 SelfTest 91:24:03
5 PPP/2 Point to Point Up B2 Inbound 91:24:00
Net Number of the dial circuit mapped to this interface
Interface
Type of interface and its instance number.
MAC/Data-Link
Type of data-link protocol configured for this dial circuit.
State Current state of the dial circuit:
Up Currently connected.
Available
Not currently connected, but available.
Disabled
Dial circuit disabled.
Down Failed to connect because of a busy dial circuit or because the
link-layer protocol is down.
ReasonReason for the current state:
nnn_Data
(Where nnn is the name of a protocol.) The circuit is up because a
protocol had data to send.
Rmt Disc
Remote Disconnect. The circuit is either down or available because
the remote destination disconnected the call.
Opr Req
Operator Request. The circuit is available because the last call was
disconnected by a monitoring command.
Inbound
The circuit is up because the circuit answered an inbound call.
Restoral
The circuit is up because of a WAN-Restoral operation.
Self Test
The circuit was configured as static (idle time=0) and successfully
connected once it was enabled.
Duration
Length of time that the circuit has been in the current state.
