MTU Supported by an LBF Board for the 10G LAN Service on Client Side Cannot Be Configured

The MTU supported by an LBF board for the 10G LAN service on client side cannot be configured.

Product

OSN6800,OSN8800,WDM

Fault Type

Optical Transponder Unit

Symptom

When the WDM interface attributes on an E3LBFS board are configured by using the NMS, the Maximum Packet Length parameter cannot be configured after Service Type is set to 10GE(LAN). By default, Maximum Packet Length is 1518.

Cause Analysis

The possible causes of the preceding problem are as follows:

• An E2LBF board supports client-side services in two modes, that is, Flow Control Mode and Transparent Transmission Mode. In Flow Control Mode, the MTU is 9600 and cannot be changed. In Transparent Transmission Mode, the MTU is invalid.
• An E3LBF board supports the client-side services only in Transparent Transmission Mode. In this mode, the board transfers service packets transmitted from the client side without limits.

Procedure

1. None.

Result

The problem is resolved.

Reference Information

None.
