./常見問題FAQ常見故障用戶無法認證通過用戶無法分配地址用戶異常斷線等注意：PPPoE上線包括Discovery階段、LCP〔LinkControlProtocol協商階段、驗證階段及IP地址分配階段,任何一步失敗都可能導致用戶上線失敗。所以PPPoE業務失敗時,可通過調試信息或業務跟蹤的信息檢查哪個階段失敗。使用調試命令或業務跟蹤信息前,首先應確認ME60數據配置是否正確。故障檢查檢查要點：認證域、IP地址池、access-type不匹配、vlan配置錯誤、radius錯誤、接口與虛模版綁定、認證方式等。配置項子項注意事項License--對PPPoX接入用戶,如果沒有License,則用戶無法上線。用戶配置用戶接入類型PPPoX接入業務的用戶均屬于普通二層用戶,接入類型必須設置為layer2-subscriber。PPPoE用戶PPPoE用戶所在的物理接口必須和虛模板接口綁定。本地帳號帳號屬性配置要正確。要允許PPP接入。狀態必須為激活狀態。認證配置認證方法對于PPPoE接入的用戶,其所在BAS接口下的認證方法應至少包括PPP。認證域需要為認證域正確配置認證方案、計費方案。Ethernet接口VLAN接入用戶所在的VLAN必須和接入的交換機接口的VLAN需要一致基礎配置地址池認證域下必須至少有一個可用的地址池。地址池配置正確且有空閑地址。在地址池中必須把靜態用戶使用的地址禁止分配。最多可以有1024個地址池。路由ME60必須有到達外部網絡的路由。RADIUS服務器RADIUS服務器組至少存在一個認證服務器,一個計費服務器。正確配置服務器IP地址、端口、協議類型及密鑰。服務器的狀態必須為UP。檢查手段：調試信息、業務跟蹤、命令查詢等。診斷流程：典型案例用戶異常下線故障原因分析：如果是PPPechofail原因即握手失敗,則可能是在ME60、二層網絡或客戶端故障。可能二層鏈路質量不太好,或用戶的業務流量太大導致報文擁塞。RADIUS下發相關屬性問題,有可能是下發的sessiontimeout或flowlimit等屬性。處理步驟使用命令displayaaaoffline-record查看用戶下線原因。檢查二層網絡配置,解決二層網絡故障。打開業務跟蹤并同時在客戶端抓包,根據抓包信息定位故障。ME60上對應虛模板視圖下使用pppkeepalive命令來調整用戶握手的時間。檢查RADIUS下發相關屬性。撥號時提示找不到服務器故障原因分析：BAS接口沒有UP。拔號客戶端設置的服務名與ME60的配置不匹配。ME60上BAS接口接入類型錯誤。BAS接口認證方法配置錯誤。PPPoE接口沒有綁定虛模板。二層網絡故障。處理步驟：使用displayinterface命令檢查BAS接口是否UP。檢查撥號客戶端設置的服務名是否和ME60配置的一致。檢查PPPoX配置是否正確。打開調試開關和業務跟蹤功能檢查二層網絡故障,檢查VLAN劃分是否正確。Radius認證失敗故障原因分析：RADIUS服務器故障。用戶名或密碼錯誤、用戶名未激活、用戶名不存在、域未激活等。處理步驟：打開RADIUS服務器調試開關,檢查是否能夠收到RADIUS認證報文。打開業務跟蹤或radius調試信息,檢查是否收到認證回應報文,報文屬性是否有錯,配置是否存在錯誤等。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協商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]――開始LCP協商階段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:
