mpusap以及mplsap查看PPP层信息

JNCX2000A>mpusap

[1] usap = 1 rowst = 2 alias = Mlppp1 epd = JiNan bwthres = 85 mrru = 1500 seqfldcomp = 2 bacp = 2 txwin = 20 gen = 1 genlsap = 0 gensize = 32 genfrm = 1 gendly = 50 genpri = 1

mlpm = 1 state = 3 nbppplink = 2 locmrru = 1500 remmrru = 1524 remseqfldcmp = 2 locseqfldcmp = 2 nbppplinkup = 2 mlpstate = 1 genstate = 3 bapstate = 3 frstate = 3 ipstate = 1 locepd = JiNan remepd = Cisco7513 bytestx = 1422744709 bytesrx = 1592512513 JNCX2000A>mplsap

[1] lsap = 1 rowst = 2 alias = PppPort17 link = E1port17

dial = 0 mru = 1500 acc = FFFFFFFF maxcfg = 10 maxterm = 2 maxfail = 10 rstime = 3 protfldcomp = 2 acfldcomp = 2 magnum = 1 lctr = 1 state = 3 physnetstate = 1 virtnetstate = 3 baddr = 0 ctrlerr = 0 long = 0 fcs = 0 locmru = 1500 remmru = 1500 remaccm = FFFFFFFF locaccm = FFFFFFFF remprotcmp = 2

locprotcmp = 2 remaccmp = 2 locaccmp = 2 bytestx = 3239061849 bytesrx = 3209305667 linkusap = 1 JNCX2000A>n

[2] lsap = 2 rowst = 2 alias = PppPort18 link = E1port18

locprotcmp = 2 remaccmp = 2 locaccmp = 2 bytestx = 3239150933 bytesrx = 3209220402 linkusap = 1

另外当IP over PPP时，PPP层的状态检查使用命令mpusap以及mplsap

mpusap的nbppplinkup表示活动的PPP链路数目，nbppplink表示定义的PPP链路数目(如果=2，则是捆绑2条链路的MLPPP)，state=3表示状态正常。(若nbppplink与nbppplinkup不相等，则有问题)。mplsap的virtnetstate = 3，physnetstate = 1表示状态正常。

8、配置备份与输入方法

PFA路由器：相关命令为NACDI、NACDP、NACCS、NACCP、NACCR Memotec路由器

在路由器数据更新时(或者检查发现custom.txt与实际配置不一时)，需要更新CUSTOM.txt文件，更新方法：

? custom.txt 文件是存在Flash中的用户脚本文件，作为数据备份，当Saved

config缺失的时候，可以用来加载系统。所以应该及时更新，更新方法目前只能通过手动方法。

? 当Saved config与custom.txt不一致时，首先用命令sysmgt config=5 把

当前custom.txt文件显示出来并保存成一个文本文件（例如ZBCX2000Acpu1.txt），按照实际配置修改后保存，再把当前的custom.txt文件用命令sysmgt config=4 删除。

更新后如何传到路由器上

通过cxaccess程序，有2种方法可以传回路由器中：

? 通过路由器的Console口――选定Transfer?Send file菜单发送,进入

choose file 窗口时，本地文件窗口内是更新过的文本文件（例如ZBCX2000Acpu1.txt），而remote file path/name一定要为大写的CUSTOM.TXT

? 通过路由器的以太网口――前提是使用cxaccess的device连接路由器，

选择菜单Transfer?Send file，进入File Transfer- TFTP设置窗口，如上的选择本地及路由器内的文件，再发送。

文件传送完成后，使用命令sysmgt config=5进一步确认。紧急情况下，如何启用custom.txt。

有2种方法可以载入custom.txt文件到系统active config中

? 输入命令sysmgt config=3 删除当前配置（saved config）, 再输入命令

sysmgt restart=3 ,或者重新关电/加电，启动路由器。由于Saved config的缺失，系统会用custom.txt加载。

? 重启路由器时，通过console口，当系统加载出现以下信息时：

Startup will continue in 2 seconds, you may enter to force factory defaults to force custom defaults to access diagnostic menu

快速按下Ctrl和B键，强迫系统调用custom.txt脚本文件。

9 发现无法通过OSS连接网元(这里OSS对菏泽而言就是CX2000) 1) 判断是否能够ping通OSS，

若无法ping通OSS，说明是IP连接问题，参见情况2

若能够ping通OSS，原因一般是OSS与网元之间X25问题，则

2) 使用命令osparam查看bufsfree参数值，正常情况下应该在3000左右，如果

降到2000以下，甚至1000、几百时，可以判断为内存不足原因导致。记录时间、原因以及bufsfree值。(路由器软件升级到4.0后，正常的bufsfree在8000左右)

3) 若osparam查看参数正常，检查X25连接状态。

注：一般此时原因是IP流量过大，影响X25呼叫的建立。此时，应该及时检查IP流量过大的原因(多数因为是病毒)，具体方法是使用安装sniffer的电脑监测每个HUB上或者二层交换机上的流量情况，可以发现异常流量。需要注意的是，二层交换机无法看到所有端口流量，需要进行镜像。(还可以使用IP仪表)

因为Memotec路由器是基于FR（X25）为内核的路由器，承载IP数据时也需要用到X25连接，当IP数据量较大时，尤其是有病毒时，随机扫描地址，导致很多个网段，需要建立了很多X25呼叫，影响纯X25呼叫的建立。

10 发现网速较慢可能原因有：

1) 广域网络带宽拥塞。可以查看设备端口流量、IP网管 2) 局域网广播包太多。方法参见上文 3) 应用程序速度慢的原因。

联系对端设置FTP服务器，测试网速。 11. 青岛告警

Warning XIM (ximHandleX25DisconnectIndication): Max Receive Packet size exc edeed (received = 140 octets, configuration rxpktsz = 128 octets).

原因?????

12. X25呼叫过程DEBUG BEC来讲

13. SNMP相关配置基础设置：

system sysName=\module alias=\

community:1 name=”public”,address=0.0.0.0,access=1,viewset=1,rowst=2 community:2 name=”private”,address=0.0.0.0,access=3,viewset=1,rowst=2 (上述命令是缺省命令，定义了RO、RW权限的SNMP。可以通过上述命令修改)

hosttrap:1 address=150.236.51.194,community=public, rowst=2(Set correct Trap Host address)

bopadmsap:21 alias=Sync1,prttrp=2,clktrp=2(Physical port Trap setting) snmp命令查看SNMP信息 dcx2000a>snmp
