Prerequisites for Configuring LAN/WAN-PHY Controller Interfaces

To perform these configuration tasks, your Cisco IOS XR software system administrator must assign you to a user group associated with a task group that includes the corresponding command task IDs. All command task IDs are listed in individual command references and in the Cisco IOS XR Task ID Reference Guide. If you need assistance with your task group assignment, contact your system administrator.

Before configuring a LAN/WAN-PHY controller, be sure that the following tasks and conditions are met:

•Your SPA must support the LAN/WAN-PHY controller. The 1-Port 10GE LAN/WAN-PHY Shared Port Adapter (SPA-1X10GE-WL-V2) supports the LAN/WAN-PHY controller.

Restrictions

LAN-PHY mode is configurable only on the 1-Port 10GE LAN/WAN-PHY Shared Port Adapter (SPA-1X10GE-WL-V2).

Information About the LAN/WAN-PHY Controllers

LAN/WAN-PHY support in Cisco IOS XR software 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 PTE between routers, the other endpoint must be an Ethernet WAN interface. WAN-PHY will not interoperate and terminate on a PoS (Packet over Sonet) or EoS (Ethernet over Sonet) port. Between devices (LTE - Line Terminating Equipment or STE - Section Terminating Equipment), the endpoints can be an Add-Drop Multiplexer (ADM) or Dense Wavelength Division Multiplexing (DWDM) OC-192c POS interfaces.

The purpose of WAN-PHY is to render 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 which can interoperate with SONET section or line level repeaters. This effectively bridges the asynchronous world of Ethernet data with synchronous SONET/SDH transport allowing 10 Gigabit Ethernet to be transparently carried over current DWDM networks without having to directly map the Ethernet frames into SONET/SDH.

At a high-level, the WIS has the following characteristics and functions:

•The WIS allows WAN-PHY equipment to generate an Ethernet data stream to be mapped to an OC-192c or VC-4-64c concatenated payload at the PHY level without any MAC or higher layer processing.

•In theory, a 10GBASE-W interface in not intended to interoperate directly with SONET/SDH equipment because WAN-PHY is not fully compliant with SONET/SDH optical and electrical specifications. In practice, SONET/SDH and 10GBASE-W interfaces can interoperate.

•From a MAC perspective, WAN-PHY does not appear any different from LAN-PHY (no WIS) with the exception of the sustained data rate. In the case of LAN-PHY the data rate is 10.3125 Gbps, while at WAN-PHY it is 9.95328 Gbps (as required by SONET/SDH).

•The WIS implements a subset of the SONET functions including creating the Section, Line, Path Overhead headers, calculating the Bit Interleaved Parity (BIP) bytes for error monitoring and managing a variety of alarms and defect indications.

Beside the frame format and data rate 10GBASE-W and Packet over SONET (POS) have very little in common:

•POS and 10GBASE-W cannot in fact interoperate on the same link since the protocol architecture is completely different. POS is based on a serial protocol like PPP whose frames are logically and physical different from Ethernet MAC frames.

•From a Service Provider point of view, POS is a L3 point-to-point service while WAN-PHY is a L2 Ethernet hand-off. WAN-PHY should be compared more properly to an Ethernet over SONET (EoS) encapsulation technology, such as ITU-T X.86 or GFP (ITU-T G.7041) where the Ethernet frame is encapsulated respectively in an HDLC-like or GFP frame.

•POS is optically and electrically compatible with SONET/SDH protocols whereas WAN-PHY is not.

•Cisco POS supports linear Automatic Protection Switching (APS) to restore link failures in 50 msec, while WAN-PHY is not designed to support APS.

•The synchronous nature of POS requires clocking to be configured either "internal" or "line" (Internal clocking is used when the POS interface is connected to another POS in back-to-back or through DWDM, while the line clocking is required when the POS is connected to a SONET/SDH add/drop multiplexer). WAH-PHY has no requirement to support line clocking.

The supported LAN/WAN-PHY cards are:

•Cisco CRS-1 Series 8-Port Ten Gigabit Ethernet Interface Module (8-10GBE-WL-XFP)

•Cisco CRS-1 Series 2x10GE WAN/LAN Flexible Interface Module (2-10GE-WL-FLEX)

•Cisco CRS-1 Series 4-Port Ten Gigabit Ethernet Interface Module (4-10GBE-WL-XFP)

How to Configure LAN/WAN-PHY Controllers

The LAN/WAN-PHY controllers are configured in the physical layer control element of the Cisco IOS XR software configuration space. By default the 1-Port 10GE LAN/WAN-PHY Shared Port Adapter boots up in WAN-PHY mode. LAN-PHY mode configuration is done using the controller wanphy command.

Configuration of LAN/WAN-PHY controllers is described in the following tasks.

•Configuring LAN-PHY Mode

•Configuring WAN-PHY Signal Failure and Signal Degrade Bit Error Rates

Note All interface configuration tasks for the POS or GE interfaces still must be performed in interface configuration mode. Refer to Configuring POS Interfaces on Cisco IOS XR Software and Configuring Ethernet Interfaces on Cisco IOS XR Software modules for more information.

Configuring LAN-PHY Mode

This task describes how to configure LAN-PHY mode on the 1-Port 10GE LAN/WAN-PHY Shared Port Adapter (SPA-1X10GE-WL-V2).

Note After configuring LAN-PHY mode and reloading the SPA, all links are in the UP state.

Tue Jan 5 23:01:18.641 PST
Interface: wanphy0_6_1_0
Configuration Mode: WAN Mode

Displays the configuration mode of the LAN/WAN-PHY controller. By default, prior to configuration of LAN-PHY mode the controller will be in WAN-PHY mode.

Step 2

configure
Example:

RP/0/RP0/CPU0:router# configure

Enters global configuration mode.

Step 3

controller wanphy interface-path-id
Example:

RP/0/RP0/CPU0:router(config)# controller wanphy 0/6/1/0

Specifies the LAN/WAN-PHY controller name in the notation rack/slot/module/port and enters wanphy configuration mode.

Step 4

lanmode on
Example:

Saves configuration changes.

•When you issue the end command, the system prompts you to commit changes:
Uncommitted changes found, commit them before 
exiting(yes/no/cancel)? [cancel]:
–Entering yes saves configuration changes to the running configuration file, exits the configuration session, and returns the router to EXEC mode.

–Entering no exits the configuration session and returns the router to EXEC mode without committing the configuration changes.

–Entering cancel leaves the router in the current configuration session without exiting or committing the configuration changes.

•Use the commit command to save the configuration changes to the running configuration file and remain within the configuration session.
Step 6

hw-module subslot interface-path-id reload
Example:

RP/0/RP0/CPU0:router# hw-module subslot 0/6/1 reload

Reloads the SPA in the notation rack/slot/module. To complete the mode change from WAN-PHY to LAN-PHY the SPA must be power-cycled.

Tue Jan 12 20:39:32.570 PST
Interface: wanphy0_6_1_0
Configuration Mode: WAN Mode

What to Do Next

All interface configuration tasks for the POS or GE interfaces still must be performed in interface configuration mode. Refer to Configuring POS Interfaces on Cisco IOS XR Software and Configuring Ethernet Interfaces on Cisco IOS XR Software modules for more information.

Configuring WAN-PHY Signal Failure and Signal Degrade Bit Error Rates

This task describes how to configure WAN-PHY Signal Failure (SF) and Signal Degrade (SD) Bit Error Rate (BER) reporting and thresholds.

A Signal Failure (SF) alarm is declared if the line bit error (B2 ) rate exceeds a user provisioned threshold (over the range of 10e-3 to 10e-9). If the B2 errors cross the SF threshold then the link is considered unreliable and the interface changes the state to down.

A Signal Degrade (SD) alarm is declared if the line bit error (B2 ) rate exceeds a user provisioned threshold (over the range of 10e-3 to 10e-9). If the B2 errors cross the SD threshold then a warning of link quality degradation will occur.

The SF or SD alarm is cleared when the B2 error count remains below the configured threshold for a period of time called the Hold on Time. Table 20 lists the configured SF and SD threshold values and the corresponding Hold on Times.
