Overview of LAN/WAN-PHY Controllers
LAN/WAN-PHY support in Cisco IOS XE Software Release 3.3.0S and later is based on the IEEE 802.3ae
standard. WAN-PHY controllers can only be used as Path Terminating Equipment (PTE). When deploying
Ethernet WAN interfaces as endpoints or as PTE between routers, the other endpoint must be an Ethernet
WAN interface. WAN-PHY does not interoperate nor terminate on a Packet over Sonet (PoS) or an Ethernet
over Sonet (EoS) port.
The purpose of WAN-PHY is to render a 10-Gigabit Ethernet compatible with the SONET STS-192c format
and data rate, as defined by ANSI, as well as the SDH VC-4-64c container specified by ITU. To achieve this
compatibility, a WAN Interface Sublayer (WIS) is inserted between the 10-Gigabit Ethernet Physical Coding
Sublayer (PCS) and the serial Physical Medium Attachment sublayer/Physical Medium Dependent sublayer
(PMA/PMD). When the controller is in WAN-PHY mode, the WIS sublayer transports 10-Gigabit Ethernet
frames in an OC-192c SONET payload that can interoperate with SONET section or line-level repeaters. This
effectively bridges the asynchronous world of Ethernet data with synchronous SONET/SDH transport, allowing
the 10-Gigabit Ethernet to be transparently carried over current DWDM networks without having to directly
map the Ethernet frames into SONET/SDH.
Following is a list of the WIS characteristics and the functions it performs:
• The WIS allows WAN-PHY equipment to generate an Ethernet data stream to be mapped to an OC-192c
• A 10GBASE-W interface cannot interoperate directly with SONET or SDH equipment because
• From a MAC perspective, WAN-PHY does not appear any different from LAN-PHY (no WIS) with
• The WIS implements a subset of the SONET functions, including creating the section, line, path overhead
