Juniper JUNOSE 11.1.X - LINK LAYER CONFIGURATION 4-7-2010, Configuration Manual

Page: 634 / 774

■
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.
■
Interface Type—Type of ATM 1483 subinterface: dynamic or static
■
Auto configure status—Setting of the autoconfiguration feature
■
dynamic—Autodetection is on; the router automatically detects the next
upper interface
■
static—Autodetection is off
■
Auto configure interface(s)—Types of dynamic upper interfaces configured
with the
auto-configure command: bridged Ethernet, IP, PPP, or PPPoE

Monitoring Upper-Layer Dynamic Interfaces and Profiles
