Display LAPD Link Info(DSP LAPDLNK)

Function

An OM command that queries the info of a specified LAPD link.

Note

1.This command can be used to query the status of the LAPD link only on the GXPUM with the CPU numbered 0, 1, and 2 and on the GXPUT with the CPU numbered 0, 1, 2, and 3.

2.You can query the information about the LAPD link by using two methods. If you query the information about all the LAPD links on a single CPU, specify "Subrack No.", "Slot No.", and "CPU No." without specifying "CES No." If you query the information about a single LAPD link, specify "CES No." without specifying "Subrack No.", "Slot No.", and "CPU No.".

Parameters

ID	Name	Description
FRAMENO	Subrack No.	Meanings:Frame No. Value range:0~11 Explanation:This parameter specifies the number of a subrack. Default value:None
SLOTNO	Slot No.	Meanings:Slot No. Value range:0~27 Explanation:This parameter specifies the number of the slot that holds the board. Default value:None
CPUNO	CPU No.	Meanings:CPU No. Value range:0~3 Content:This parameter specifies the number of the CPU. Recommended value(default value):none
CESNO	CES No.	Meaning: logical link number Value range: 0-26623 Explanation: A key field of an LAPD link that indicates the LAPD link to be queried. You can obtain the field through the LST LAPDLNK command. Default value: None

Example

Query the status of the LAPD link (CES No. = 0):
DSP LAPDLNK: CESNO=0;

The result is as follows:
+++    HUAWEI        2009-01-22 09:10:22
O&M    #3142
%%DSP LAPDLNK: CESNO=0;%%
RETCODE = 0  Operation succeeded

                                      UsageStatus  =  Fault
    Number of packets sent correctly on LAPD link  =  4484
Number of packets received correctly on LAPD link  =  0
    Number of discarded packets sent on LAPD link  =  1
Number of discarded packets received on LAPD link  =  0
(Number of results = 1)

Output Description

Domain Name	Description
Usage Status	"Normal" indicates that the link works properly; "Congested" indicates that the link is congested because of overflow; "Faulty" indicates that the link is blocked and cannot receive or transmit data.
Number of packets sent correctly on LAPD link	This parameter is measured only on the board that carries the LAPD link.
Number of packets received correctly on LAPD link	This parameter is measured only on the board that carries the LAPD link.
Number of discarded packets sent on LAPD link	This parameter is measured only on the board that carries the LAPD link.
Number of discarded packets received on LAPD link	This parameter is measured only on the board that carries the LAPD link.
