Field Description
Phys desc Physical descriptor. A string learned from the switch that identifies the
i
nterface.
Log intf Logical interface ID. This 32-bit entity, learned from the switch, uniquely
id
entifies the interface.
Interface The (Cisco IOS) interface name.
IF status Overall interface status. Can be “up,” “down,” or “administratively down.”
Min VPI Minimum virtual path identifier. Indicates the low end of the VPI range
co
nfigured on the switch.
Max VPI Maximum virtual path identifier. Indicates the high end of the VPI range
co
nfigured on the switch.
Min VCI Minimum virtual path identifier. Indicates the high end of the VCI range
co
nfigured on the switch.
Max VCI Maximum virtual channel identifier. Indicates the high end of the VCI range
c
onfigured on, or determined by, the switch.
IFC state Operational state of the interface, according to the switch. Can be one of the
f
ollowing:
• FAILED_EXT (that is, an external alarm)
• FAILED_INT (indicates the inability of the MPLS LSC to
communicate with the VSI slave controlling the interface, or another
internal failure)
• REMOVED (administratively removed from the switch)
Maximum cell rate Maximum cell rate for the interface, which has been configured on the
s
witch (in cells per second).
Available channels Indicates the number of channels (endpoints) that are currently free to be
us
ed for cross-connects.
Available cell rate
(f
orward)
Cell rate that is currently available in the forward (that is, ingress) direction
for new cross-connects on the interface.
Available cell rate
(b
ackward)
Cell rate that is currently available in the backward (that is, egress) direction
for new cross-connects on the interface.
