Field Description
ATM2/4/0, State UP
Name of the interface to which the PVC-groups belong, and the physical and
administrative states of the interface.
State of an interface (not a subinterface):
•
UP
—The interface is both physically and administratively up.
•
DOWN
—The interface is in either of the following states:

The interface is administratively up but physically down (probably
because no physical link is available or the link has failed).

The interface is administratively down (shut down by using
the
shutdown
command).
State of a subinterface:
•
UP
—The interface is administratively up. The parent interface is both
physically and administratively up.
•
DOWN
—The interface or its parent interface was shut down by using
the
shutdown
command, or the parent interface is physically down.
Encapsulation
AAL5 encapsulation type of the PVC-group. It can only be SNAP, which is the
Logical Link Control (LLC)/Subnet Access Protocol (SNAP) encapsulation type.
Protocol
Upper-layer protocol running on the PVC-group:
•
PPP
—PPP protocol.
•
IP
—IP protocol.
•
ETH
—Ethernet protocol.
•
None
—No protocol is configured.
PVC name PVC name.
N/A
means no PVC name.
Precedence
Priority of the IP packets carried by the PVC in the PVC-group:
•
Default
—Default PVC. IP packets without a priority configured are
transmitted through the default PVC.
•
a-b
—Lowest and highest priorities of the IP packets carried by the PVC.
The value range for
a
and
b
is 0 to 7.
a
is smaller than
b
.
•
c
—Priority of the IP packets carried by the PVC, in the range of 0 to 7.
•
-
—No priority is configured for IP packets carried by the PVC.
State
PVC state:
•
UP
—The following states are up:

State of the ATM interface to which the PVC belongs.

Shutdown state.

OAM state.
•
DOWN
—One or more of the following states is down:

State of the ATM interface to which the PVC belongs.

Shutdown state.

OAM state.
