本文档介绍如何在各种情况下确定通过以应用为中心的基础设施(ACI)交换矩阵的数据包流。
本文档没有任何特定的要求。
本文档中的信息基于下列硬件和软件版本:
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。如果您使用的是真实网络,请确保您已经了解所有命令的潜在影响。
本节介绍可能使用ACI交换矩阵的各种情况以及如何确定数据包流。
本节介绍如何验证同一枝叶交换机上同一终端组(EPG)/网桥域(BD)内两个终端的硬件编程和数据包流。如果虚拟机(VM)在同一主机上运行,由于它们位于同一EPG中,则流量会隔离到主机上的虚拟交换机(VS),并且流量永远不必离开主机。如果VM在不同主机上运行,则以下信息适用。
您应首先检验的是是否获取了枝叶交换机上源和目标IP地址的介质访问控制(MAC)地址信息。以下是本示例中使用的MAC和IP地址信息:
输入show mac address-table命令以验证以下信息:
leaf2# show mac address-table
Legend:
* - primary entry, G - Gateway MAC, (R) - Routed MAC, O - Overlay MAC
age - seconds since last seen,+ - primary entry using vPC Peer-Link,

* 19 0050.5695.248f dynamic - F F eth1/31
如图所示,系统获取同一VLAN中两个终端的MAC地址。此VLAN是独立于平台(PI)的VLAN,对每台交换机都具有本地意义。要验证这是否是正确的PI VLAN,请连接到vsh_lc,然后在CLI中输入以下命令:
module-1# show system internal eltmc info vlan brief

HW_VlanId是Broadcom使用的VLAN。VlanId是PI VLAN,它映射到从VLAN池派生的Access_enc VLAN 291,并且是传播到分布式虚拟交换机(DVS)端口组的VLAN:
由于此流量在同一BD和同一VLAN中,因此应在Broadcom ASIC上本地交换流量。要验证Broadcom在硬件中是否有正确的条目,请连接到Broadcom外壳并查看第2层(L2)表:

输出显示Broadcom ASIC编程正确,流量应在VLAN 17中本地交换。
本节介绍如何验证同一EPG/BD中不同枝叶交换机上两个终端的硬件编程和数据包流。
您首先应该检验的是,是否已获知枝叶交换机上源IP地址和目的IP地址的MAC地址信息。以下是本示例中使用的MAC和IP地址信息:
在两台枝叶交换机的CLI中输入show mac address-table命令,以验证以下信息:
leaf2# show mac address-table
Legend:
* - primary entry, G - Gateway MAC, (R) - Routed MAC, O - Overlay MAC
age - seconds since last seen,+ - primary entry using vPC Peer-Link,

leaf_1# show mac address-table
Legend:

27 0050.5695.17b7 dynamic - F F tunnel7
* 28 0050.5695.bd89 dynamic - F F eth1/25
如输出所示,源IP地址在第二个枝叶交换机(leaf2)上获知,而目的IP地址在第一个枝叶交换机(leaf_1)上获知。 由于这些流量位于不同的枝叶交换机上,因此必须将流量发送到第二台枝叶交换机上的NorthStar ASIC,以便流量可以上游发送到主干交换机。要遵循NorthStar逻辑,请连接到线卡vsh。

在这种情况下,帧通过本地TEP的源IP地址和列出的TEP的目的IP地址封装在iVXLAN中。根据ELTMC输出,该BD的VXLAN ID为15761386,因此这是放入VXLAN数据包的ID。当流量到达另一端时,它被解封,并且由于目的MAC地址是本地的,因此它会从Broadcom的l2 show命令中从端口转发。
本节介绍如何验证不同EPG中但具有相同BD的两个终端的硬件编程和数据包流。流量流向同一枝叶交换机。这也称为物理本地到物理本地(PL到PL)桥接数据包。 它是桥接的,因为允许两个封装VLAN之间通信,而无需第3层(L3)接口执行路由。
您应首先检验的是枝叶交换机上源IP地址和目标IP地址的MAC地址信息是否在预期接口上获取(本例中为1/48)。 以下是本示例中使用的MAC和IP地址信息:
在CLI中输入show mac address-table命令以验证以下信息:
leaf1# show mac address-table | grep 908b
* 34 0050.5695.908b dynamic - F F eth1/48
leaf1# show mac address-table | grep bd89
* 38 0050.5695.bd89 dynamic - F F eth1/48
然后,您应进入Broadcom(BCM)外壳,并验证BCM是否获取了正确的MAC地址信息:
bcm-shell.0> l2 show
mac=00:50:56:95:bd:89 vlan=55 GPORT=0x30 modid=0 port=48/xe47
mac=00:50:56:95:90:8b vlan=54 GPORT=0x30 modid=0 port=48/xe47 Hit
输出显示BCM已获知MAC地址信息;但是,MAC地址位于不同的VLAN中。这是预期的,因为流量来自具有不同封装VLAN(不同EPG)的主机。
输入ELTMC,以验证BCM外壳中显示的HW_VlanID与两个封装VLAN的BD VLAN对应:

在此ELTMC输出中,您可以看到每个条目的HW_VlanId映射到流量进入交换机时标记的Access_enc(检查VMware端口组以验证其是否虚拟化),以及VlanId是出现在MAC地址表。在本例中,这是桥接连接,因为BD VLAN相同(两者都在VLAN 54上)。 下图显示BCM与NorthStar的交互:
NorthStar调整数据包,使用目的IP地址的HW_VlanId重写出口帧。这样,BCM在该VLAN中具有本地命中,并通过端口1/48发送该帧。
本节介绍如何验证使用不同BD的不同EPG中两个终端的硬件编程和数据包流。流量流向同一枝叶交换机,但必须路由。这也称为PL到PL路由数据包。
您应首先检验的是,在中,枝叶交换机上源IP地址和目标IP地址的MAC地址信息是否都是通过预期接口获取的(本例中为1/48)。 以下是本示例中使用的MAC和IP地址信息:
虽然您可以查看MAC地址表以验证L2信息,但L3路由流量解决方案的一个重要部分是终端管理器(EPM)。 EPM是跟踪特定设备上所有终端的过程。
验证EPM是否了解第一台枝叶交换机(Leaf1)上的两个终端:

此输出中的VRF vnid值是相同的,因为两个路由都是路由表(相同情景)中相同虚拟路由和转发(VRF)的一部分。 BD vnid值不同,因为两个终端位于不同的BD中。
正如您查看NorthStar表以验证L2级MAC地址的硬件编程一样,您也可以执行同样的操作以验证L3表:
