ME60故障处理trace详细解析

./常见问题FAQ常见故障用户无法认证通过用户无法分配地址用户异常断线等注意：PPPoE上线包括Discovery阶段、LCP〔LinkControlProtocol协商阶段、验证阶段及IP地址分配阶段,任何一步失败都可能导致用户上线失败。所以PPPoE业务失败时,可通过调试信息或业务跟踪的信息检查哪个阶段失败。使用调试命令或业务跟踪信息前,首先应确认ME60数据配置是否正确。故障检查检查要点：认证域、IP地址池、access-type不匹配、vlan配置错误、radius错误、接口与虚模版绑定、认证方式等。配置项子项注意事项License--对PPPoX接入用户,如果没有License,则用户无法上线。用户配置用户接入类型PPPoX接入业务的用户均属于普通二层用户,接入类型必须设置为layer2-subscriber。PPPoE用户PPPoE用户所在的物理接口必须和虚模板接口绑定。本地帐号帐号属性配置要正确。要允许PPP接入。状态必须为激活状态。认证配置认证方法对于PPPoE接入的用户,其所在BAS接口下的认证方法应至少包括PPP。认证域需要为认证域正确配置认证方案、计费方案。Ethernet接口VLAN接入用户所在的VLAN必须和接入的交换机接口的VLAN需要一致基础配置地址池认证域下必须至少有一个可用的地址池。地址池配置正确且有空闲地址。在地址池中必须把静态用户使用的地址禁止分配。最多可以有1024个地址池。路由ME60必须有到达外部网络的路由。RADIUS服务器RADIUS服务器组至少存在一个认证服务器,一个计费服务器。正确配置服务器IP地址、端口、协议类型及密钥。服务器的状态必须为UP。检查手段：调试信息、业务跟踪、命令查询等。诊断流程：典型案例用户异常下线故障原因分析：如果是PPPechofail原因即握手失败,则可能是在ME60、二层网络或客户端故障。可能二层链路质量不太好,或用户的业务流量太大导致报文拥塞。RADIUS下发相关属性问题,有可能是下发的sessiontimeout或flowlimit等属性。处理步骤使用命令displayaaaoffline-record查看用户下线原因。检查二层网络配置,解决二层网络故障。打开业务跟踪并同时在客户端抓包,根据抓包信息定位故障。ME60上对应虚模板视图下使用pppkeepalive命令来调整用户握手的时间。检查RADIUS下发相关属性。拨号时提示找不到服务器故障原因分析：BAS接口没有UP。拔号客户端设置的服务名与ME60的配置不匹配。ME60上BAS接口接入类型错误。BAS接口认证方法配置错误。PPPoE接口没有绑定虚模板。二层网络故障。处理步骤：使用displayinterface命令检查BAS接口是否UP。检查拨号客户端设置的服务名是否和ME60配置的一致。检查PPPoX配置是否正确。打开调试开关和业务跟踪功能检查二层网络故障,检查VLAN划分是否正确。Radius认证失败故障原因分析：RADIUS服务器故障。用户名或密码错误、用户名未激活、用户名不存在、域未激活等。处理步骤：打开RADIUS服务器调试开关,检查是否能够收到RADIUS认证报文。打开业务跟踪或radius调试信息,检查是否收到认证回应报文,报文属性是否有错,配置是否存在错误等。PPPOETrace<ME60-3><ME60-3>tmInfo:Currentterminalmonitorison.<ME60-3>tdInfo:Currentterminaldebuggingison.<ME60-3><ME60-3>dt0<ME60-3>Dec14201013:17:08.230.1+08:00ME60-3BTRC/7/BTRC_DebugInfo:[objectID=1][slotID=3][PPPOE][userinfo:MACAddress:0001-0101-0102Interface:GigabitEthernet3/0/8.99PEVLANID:164AccessMode:PPPoE][traceinfo:ReceivePADIpacket:ffffffffffff0001010101028100e0a4886311090000000e010100000103000600010101010201020007517569647761790000000000000000000000]Dec14201013:17:08.230.2+08:00ME60-3BTRC/7/BTRC_DebugInfo:[objectID=1][slotID=3][PPPOE][userinfo:MACAddress:0001-0101-0102Interface:GigabitEthernet3/0/8.99PEVLANID:164AccessMode:PPPoE][traceinfo:SendPADOpacket:00010101010200259eb067788100e0a48863110700000019010100000103000600010101010201020007517569647761790000000000000000000000]Dec14201013:17:08.230.3+08:00ME60-3BTRC/7/BTRC_DebugInfo:[objectID=1][slotID=3][PPPOE][userinfo:MACAddress:0001-0101-0102Interface:GigabitEthernet3/0/8.99PEVLANID:164AccessMode:PPPoE][traceinfo:ReceivePADRpacket:00259eb067780001010101028100e0a4886311190000000e010100000103000600010101010200000000000000000000000000000000000000000000]Dec14201013:17:08.230.4+08:00ME60-3BTRC/7/BTRC_DebugInfo:[objectID=1][slotID=3][PPPOE][userinfo:MACAddress:0001-0101-0102Interface:GigabitEthernet3/0/8.99PEVLANID:164AccessMode:PPPoE][traceinfo:SendPADSpacket:00010101010200259eb067788100e0a4886311650006000e010100000103000600010101010200000000000000000000000000000000000000000000]Dec14201013:17:08.230.5+08:00ME60-3BTRC/7/BTRC_DebugInfo:[objectID=1][slotID=3][PPPOE][userinfo:MACAddress:0001-0101-0102Interface:GigabitEthernet3/0/8.99PEVLANID:164AccessMode:PPPoE][traceinfo:SendPADSpacketsuccessfully,notifyPPPup<SessionID=6>]――到此sessionid协商OKDec14201013:17:08.230.6+08:00ME60-3BTRC/7/BTRC_DebugInfo:[objectID=1][slotID=3][PPP][userinfo:MACAddress:0001-0101-0102Interface:GigabitEthernet3/0/8.99PEVLANID:164AccessMode:PPPoE][traceinfo:ReceivedUPevent]――开始LCP协商阶段Dec14201013:17:08.230.7+08:00ME60-3BTRC/7/BTRC_DebugInfo:[objectID=1][slotID=3][PPP][userinfo:MACAddress:0001-0101-0102Interface:GigabitEthernet3/0/8.99PEVLANID:164AccessMode:PPPoE][traceinfo:NotifyNCPdown]Dec14201013:17:08.230.8+08:00ME60-3BTRC/7/BTRC_DebugInfo:[objectID=1][slotID=3][PPP][userinfo:MACAddress:0001-0101-0102Interface:GigabitEthernet3/0/8.99PEVLANID:164AccessMode:PPPoE][traceinfo:LCPFSMopenevent]Dec14201013:17:08.230.9+08:00ME60-3BTRC/7/BTRC_DebugInfo:[objectID=1][slotID=3][PPP][userinfo:MACAddress:0001-0101-0102Interface:GigabitEthernet3/0/8.99PEVLANID:164AccessMode:PPPoE][traceinfo:Resetoptionsatlcpphase,tobereadytonegotiate]Dec14201013:17:08.230.10+08:00ME60-3BTRC/7/BTRC_DebugInfo:[objectID=1][slotID=3][PPP][userinfo:MACAddress:0001-0101-0102Interface:GigabitEthernet3/0/8.99PEVLANID:164AccessMode:PPPoE][traceinfo:LCPFSMupevent]Dec14201013:17:08.240.1+08:00ME60-3BTRC/7/BTRC_DebugInfo:[objectID=1][slotID=3][PPP][userinfo:MACAddress:0001-0101-0102Interface:GigabitEthernet3/0/8.99PEVLANID:164AccessMode:PPPoE][traceinfo:PPPsendlcpREQ!]Dec14201013:17:08.240.2+08:00ME60-3BTRC/7/BTRC_DebugInfo:[objectID=1][slotID=3][PPP][userinfo:MACAddress:0001-0101-0102Interface:GigabitEthernet3/0/8.99PEVLANID:164AccessMode:PPPoE][traceinfo:SendConfigurationRequestpacket:ff03c02101010013010405d40305c22305050639a94bd9]Dec14201013:17:08.240.3+08:00ME60-3BTRC/7/BTRC_DebugInfo:[objectID=1][slotID=3][PPP][userinfo:MACAddress:0001-0101-0102Interface:GigabitEthernet3/0/8.99PEVLANID:164AccessMode:PPPoE][traceinfo:ReceivedlcpnegotiationpacketinlcpnegotiationphaseorEchoPacketff03c0210100000e010405c8050601000001]Dec14201013:17:08.240.4+08:00ME60-3BTRC/7/BTRC_DebugInfo:
