Monitoring ATM
Field descriptions
Interface Interface identifier
ATM-Prot One of the following ATM protocol types:
RFC-1483 Multiprotocol encapsulation over AAL5
NBMA Nonbroadcast multiaccess interface
ATM/MPLS Local ATM passthrough interface
VCD Virtual circuit descriptor
VPI Virtual path identifier
VCI Virtual circuit (or channel) identifier
Circuit Type Type of circuit: PVC
Encap Administered encapsulation method based on what was configured
with the atm pvc command
MTU Maximum transmission unit size for the interface
Status One of the following ATM 1483 subinterface states:
absent Represents the notPresent state and indicates that, although
the SRP detects the ATM 1483 subinterface, the module on which the
subinterface resides has not completed booting up, has failed, or is
disabled.
dormant Indicates that the ATM 1483 subinterface is performing
autodetection of one or more upper-layer encapsulation types and is
waiting to receive a packet of that type on a lower-layer interface. An
ATM 1483 subinterface transitions from the dormant state to the up
state when the router receives a valid packet of the specified
encapsulation type on the interface.
dormantLockout Indicates that a dormant ATM 1483 subinterface has
one or more upper-layer encapsulation types currently undergoing
encapsulation type lockout. An ATM 1483 subinterface transitions from
the dormantLockout state to the dormant state when the lockout time
expires for all upper-layer encapsulation types undergoing lockout. An
ATM 1483 subinterface transitions from the dormantLockout state to
the up state when the router receives a valid packet for an encapsulation
type that is configured for autodetection but is not undergoing lockout.
down Indicates that the ATM 1483 subinterface is administratively
disabled or has a circuit that is down or not configured.
lowerLayerDown Indicates that a lower-layer interface below the
ATM 1483 subinterface is down.
up Indicates that the ATM 1483 subinterface is up and able to transfer
data. For an ATM 1483 subinterface that supports one or more dynamic
upper-layer interfaces, indicates that the router has created the dynamic
upper-layer interface or is in the process of creating it.
