Ethernet Card Software Feature and Configuration Guide, R7.2
Chapter 20 POS on ONS Ethernet Cards
POS Encapsulation Types
Note
Cisco proprietary RPR requires LEX encapsulation on all ML-Series cards. IEEE 802.17 RPR is not
configurable and uses IEEE 802.17b encapsulation.
Note
When over GFP-F, it is standard Mapped Ethernet over GFP-F according to ITU-T G.7041.
GFP-F framing is only supported on nodes running Software Release 5.0 and later. The ML100T-12 and
ML1000-2 cards also require field programmable gate array (FPGA) version 4.0 or later for GFP-F
framing.
POS Encapsulation Types
The ONS Ethernet cards support five POS encapsulation methods: Cisco Ethernet-over-SONET LEX
(LEX), Cisco HDLC, Point-to-Point Protocol/Bridging Control Protocol (PPP/BCP), IEEE 802.17b
,
and
E-Series proprietary. The ONS Ethernet source card and destination card must be configured with the
same POS encapsulation to interoperate. All ONS Ethernet cards do not interoperate or support all types
of encapsulation.
IEEE 802.17b
IEEE 802.17b encapsulation is the set encapsulation when the ML-Series card mode is 802.17. It is only
supported on the ONS 15454 and ONS 15454 SDH ML-Series cards in Release 7.2 and later.
Figure 20-2 illustrates the IEEE 802.17b extended data frame used by the ML-Series card. It is used with
bridging. For comparison, the IEEE 802.17 basic data frame for IP only networks is also shown. The
extended data frame adds an extended destination address and extended source address to the basic data
frame.
