Issue Description

Version: V600R003C00SPCa00

Patch: V600R003SPC012

Problem description: To activate 1 a frame relay access VPN Circuit, the equipment only 5/2 sub-slot card Serial Port, when configuration it, i found the interface cannot be configured to FR Mode, warning information as follows:

[SD-YT - HGTX-S -1 CN2 - Serial5 / 2/0 / 3:0 ] link - protocolfr

Handling Process

Five Slot 2-subslot Portlow CPOS Support E1 , T1 , E3 , T3 , E1 -FR , T1 -FR Work mode, default condition, work mode for E1 Can be based on actual application requirements, manually adjustment. The following is different working mode, support for layer-2 protocol situation:

E1 Mode : SupportATM, IMA, TDM, PPP, HDLC.

E1 -fr Mode : SupportTDM, FR, PPP, HDLC.

E3 Mode : SupportTDM (except FLEX_2XCPOS_CARD), PPP, HDLC.

T1 Mode : SupportATM, IMA, TDM, PPP, HDLC.

T1 -fr Mode : SupportTDM, FR, PPP, HDLC.

T3 Mode : SupportPPP, HDLC.

Here is sub-card information:

And config Slot5 2-subcard CPOS Work mode is E1 -fr,  the problem is still not resolve, prompting that error information as above are the same. Note: config subcard work mode, the card restart. Information is as follows:

Root Cause

Board and subcard working mode does not support FR, currently.

Solution

You need to modify board work mode for Fr-mode , subccard work mode for T1 -fr.

Suggestions

Some protocol conflict on lower-protocal. It need to work in different mode and switch. Subcard have work mode, board have work mode also. Therefore, when config protocol, if work mode does not support, modify subbard work mode, you need to modify board working mode also.
