排除vEdge双向转发检测和数据平面连接问题
简介
本文档介绍控制平面连接后的vEdge数据平面连接问题，但是站点之间没有数据平面连接。
先决条件
要求
思科建议了解解决方Cisco Software Defined Wide Area Network (SDWAN) 案。
使用的组件
本文档不限于特定的软件和硬件版本。 本文档重点介绍vEdge平台。
本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您的网络处于活动状态，请确保您了解所有命令的潜在影响。
对于思科边缘路由器(控制器模式下的Cisco IOS® XE路由器)，请阅读。
控制平面信息
检查控制本地属性
要检查vEdge上接口 Wide Area Network (WAN) 的状态，请使用命令show control local-properties wan-interface-list。
在此输出中，您可以看到RFC 4787 Network Address Translation (NAT) Type。
当vEdge位于NAT设备（防火墙、路由器等）后面时，使用公有和私有IPv4地址、公有和私有源端口来构建数据平面隧 User Datagram Protocol (UDP) 道。
您还可以找到隧道接口的状态、颜色和已配置的最大控制连接数。

检查控制连接
检查控制连接必须确保未形成数据平面隧道的颜色与重叠中的控制器建立了控制连接。
否则，vEdge不会将信 Transport Locator (TLOC) 息发送到vSmart通 Overlay Management Protocol (OMP)道。
您可以使用命令验证它是否可 show control connections 用，并查找状 connect 态。

或者，在tunnel interfacemax-control-connections 0 部分下方的选定接口中设置。

重叠管理协议验证是否已从vEdge通告OMP TLOC
验证是否已从vEdge通告OMP TLOC无法发送OMP TLOC，因为接口尝试通过该颜色形成控制连接，并且无法访问控制器。
检查颜色（数据隧道）是否将该特定颜色的TLOC发送到vSmarts。
使用命 show omp tlocs advertised 令检查发送到OMP对等体的TLOC。
示例：颜色 mpls 和 gold。未将TLOC发送到vSmart以实现彩色MPLS。

命令show tunnel statistics
命令show tunnel statistics可以 show tunnel statistics 显示有关数据平面隧道的信息。您可以确定是否为vEdge之间的特定IPSEC隧道发送或接收数据包。
这有助于您了解数据包是否到达每一端，并隔离节点之间的连接问题。

访问列表查看输出后，访问列表是一个非常有用的必要步 show bfd sessions 骤。
现在私有和公共IP和端口已知，您可以创建一个以与SRC_PORT、DST_PORT、SRC_IP、DST_IP匹 Access Control List (ACL) 配。
这有助于验证已发送和已接收的BFD消息。
您可以在此处找到ACL配置的示例：
policy access-list checkbfd-out sequence 10 match source-ip 192.168.0.92/32 destination-ip 198.51.100.187/32 source-port 12426 destination-port 12426 ! action accept count bfd-out-to-dc1-from-br1 ! !
default-action accept
!
access-list checkbfd-in sequence 20 match source-ip 198.51.100.187/32 destination-ip 192.168.0.92/32 source-port 12426 destination-port 12426 ! action accept count bfd-in-from-dc1-to-br1 ! ! default-action accept !
vpn 0
interface ge0/0
access-list checkbfd-in in
access-list checkbfd-out out
!
!
!在本例中，此ACL使用两个序列。序列10匹配从此vEdge发送到对等体的BFD消息。序列20则相反。
它与源(Private)端口和目标(Public)端口匹配。如果vEdge使用NAT，请确保检查正确的源端口和目标端口。

网络地址转换如何使用工具stun-client检测NAT映射和过滤器。
如何使用工具stun-client检测NAT映射和过滤器。如果您已完成所有步骤，并且已支持NAT，则下一步是识别行 UDP NAT Traversal (RFC 4787) Map and Filter 为。
当vEdge位于NAT设备后面时，此工具用于发现本地vEdge外部IP地址。
此命令获取设备的端口映射，并可以选择性地发现本地设备和服务器（公共服务器：示例google stun服务器）之间的NAT的相关属性。
vEdge1# tools stun-client vpn 0 options "--mode full --localaddr 192.168.12.100 12386 --verbosity 2 stun.l.google.com 19302" stunclient --mode full --localaddr 192.168.12.100 stun.l.google.com in VPN 0 Binding test: success

Nat behavior: Address Dependent Mapping

Nat filtering: Address and Port Dependent Filtering在软件的较新版本中，语法可能会略有不同：
vEdge1# tools stun-client vpn 0 options "--mode full --localaddr 192.168.12.100 --localport 12386 --verbosity 2 stun.l.google.com 19302"
在本示例中，您使用连接到Google STUN服务器的UDP源端口12386执行完整的NAT检测测试。
此命令的输出为您提供了NAT行为以及基于RFC 4787的NAT过滤器类型。
vEdge1# show running-config vpn 0 interface ge0/0 vpn 0 interface ge0/0 ip address 10.19.145.2/30 ! tunnel-interface encapsulation ipsec color gold max-control-connections 1 no allow-service bgp allow-service dhcp allow-service dns no allow-service icmp no allow-service sshd no allow-service netconf no allow-service ntp no allow-service ospf allow-service stun ! no shutdown ! !这显示了STUN术语（全锥NAT）与RFC 4787（UDP的NAT行为）之间的映射。
CLI中使用的数据平面隧道支持的NAT类型“发送”
CLI中使用的数据平面隧道支持的NAT类型“发送”在大多数情况下，您的公共颜色（如商业Internet或公共Internet）可以直接连接到Internet。
在其他情况下，vEdge WAN接口和实际互联网服务提供商后面有一个NAT设备。
通过这种方式，vEdge可以具有私有IP，而其它设备（路由器、防火墙等）可以是具有面向公有IP地址的设备。
如果您的NAT类型不正确，则可能是不允许形成数据平面隧道的最常见原因之一。以下是支持的NAT类型。
防火墙
防火墙如果您已选中NAT及其不在不受支持的Source和Destination类型中，则防火墙可能会阻止用于形成隧道的端 Data Plane 口。
确保这些端口在数据平面连接的防火墙中处于打开状态 vEdge to vEdge Data Plane:
UDP12346到13156
对于从vEdge到控制器的控制连接：
UDP12346到13156
TCP 23456到24156
确保打开这些端口，以便成功连接数据平面隧道。
当您检查用于数据平面隧道的源端口和目标端口时，可以使用 show tunnel statistics 或， show bfd sessions | tab 但不 show bfd sessions能。
它不显示任何源端口，只显示目标端口，如您所见：

!DSCP标记流量的ISP问题
DSCP标记流量的ISP问题默认情况下，从vEdge路由器到控制器的所有控制和管理流量通过DTLS或TLS连接传输，并标有DSCP值CS6（48个十进制）。
对于数据位置隧道流量，vEdge路由器使用IPsec或GRE封装来相互发送数据流量。
为了进行数据平面故障检测和性能测量，路由器会定期相互发送BFD数据包。
这些BFD数据包还使用DSCP值CS6（48个十进制）进行标记。
从ISP的角度来看，此类流量被视为具有DSCP值CS6的UDP流量，因为vEdge路由器和SD-WAN控制器会复制默认情况下标记为外部IP报头的DSCP。
以下是tcpdump在传输ISP路由器上运行时的外观：
14:27:15.993766 IP (tos 0xc0, ttl 64, id 44063, offset 0, flags [DF], proto UDP (17), length 168) 192.168.109.5.12366 > 192.168.20.2.12346: [udp sum ok] UDP, length 140 14:27:16.014900 IP (tos 0xc0, ttl 63, id 587, offset 0, flags [DF], proto UDP (17), length 139) 192.168.20.2.12346 > 192.168.109.5.12366: [udp sum ok] UDP, length 111 14:27:16.534117 IP (tos 0xc0, ttl 63, id 0, offset 0, flags [DF], proto UDP (17), length 157) 192.168.109.5.12366 > 192.168.110.6.12346: [no cksum] UDP, length 129 14:27:16.534289 IP (tos 0xc0, ttl 62, id 0, offset 0, flags [DF], proto UDP (17), length 150) 192.168.110.6.12346 > 192.168.109.5.12366: [no cksum] UDP, length 122 如图所示，所有数据包都标有TOS字节0xc0，也称为DS字段(等于十进制192或二进制的110 000 00。
前6个高位对应于DSCP位值（十进制或CS6为48）。
输出中的前2个数据包对应于控制平面隧道，其余2个数据包对应于数据平面隧道流量。
根据数据包长度和TOS标记，它可以高把握地断定是BFD数据包（RX和TX方向）。这些数据包也使用CS6进行标记。
有时，一些服务提供商（尤其是MPLS L3 VPN/MPLS L2 VPN服务提供商）维护不同的SLA，并且可以根据DSCP标记以不同方式处理不同类别的流量。
例如，如果您有高级服务来优先处理DSCP EF和CS6语音和信令流量。
由于优先级流量几乎始终受到管制，即使不超出上行链路的总带宽，这种类型的流量数据包丢失也会出现，因此BFD会话也会出现抖动。
在某些情况下，如果服务提供商路由器上的专用优先级队列不足，您不会看到正常流量有任何丢弃(例如，当您从vEdge路由器运行简单ping时)。
这是因为此类流量使用默认DSCP值0进行标记，如下所示（TOS字节）：
15:49:22.268044 IP (tos 0x0, ttl 62, id 0, offset 0, flags [DF], proto UDP (17), length 142) 192.168.110.5.12366 > 192.168.109.7.12346: [no cksum] UDP, length 114 15:49:22.272919 IP (tos 0x0, ttl 62, id 0, offset 0, flags [DF], proto UDP (17), length 142) 192.168.110.5.12366 > 192.168.109.7.12346: [no cksum] UDP, length 114 15:49:22.277660 IP (tos 0x0, ttl 62, id 0, offset 0, flags [DF], proto UDP (17), length 142) 192.168.110.5.12366 > 192.168.109.7.12346: [no cksum] UDP, length 114 15:49:22.314821 IP (tos 0x0, ttl 62, id 0, offset 0, flags [DF], proto UDP (17), length 142) 192.168.110.5.12366 > 192.168.109.7.12346: [no cksum] UDP, length 114 但与此同时，您的BFD会话会摆动：

调试BFD如果需要更深入的调查，请在vEdge路由器上运行BFD调试。
转发流量管理器(FTM)负责vEdge路由器上的BFD操作，因此您需要 debug ftm bfd它。
所有调试输出都存储 /var/log/tmplog/vdebug 在文件中，如果您希望控制台上出现这些消息(类似于Cisco IOS行terminal monitor 为)，则可以使monitor start /var/log/tmplog/vdebug用。
要停止日志记录，您可以使用 monitor stop /var/log/tmplog/vdebug
