IfIndex Table Display Definitions
Interface Extension Type
The interface extension type, shown as IfExtType in the display above, describes
the port, protocol, service, or other interface identified by the IfIndex. The
following table describes some of the common interface extension types seen on
the Passport 4460.
PPA Number
The Point of Physical Attachment (PPA) is not a literal physical point of
attachment, but is an internal identifier for the Passport 4460 code. Each PPA can
have one or more IfIndexes associated with it, but the PPA numbers are unique
only within the module; they are not unique across all devices or slots.
ethernetCsmacd The Ethernet port (10BASE-T or AUI) on the base module. This
interface is always assigned IfIndex 1.
propVirtual A virtual port on the Passport 4460. Virtual ports are used to direct
traffic across a WAN link. By default, there are two virtual ports,
assigned IfIndexes 2 and 4. For more information on virtual ports,
see the Online Documentation,
LAN Services
.
propMultiplexor A physical port on the Passport 4460. There are three physical
ports on the base module.
frameRelay A frame relay protocol implemented on a physical port.
frameRelay
refers to the switching protocol used for PANL and
RFC1490 netlinks.
frameRelayService A frame relay protocol implemented on a physical port.
frameRelayService
refers to Frame Relay DCE service.
v35 The connector type for a physical port. V.35 is one of several
connector types supported on Passport 4460 physical ports. For
more information, refer to
