Überprüfen Sie mithilfe des Ping-Tests, ob der NCS6K-Paketpfad langsam weitergeleitet wird.
Inhalt
Hintergrundinformationen
Zwischen NCS6K und der herkömmlichen IOS-XR-Plattform besteht ein wesentlicher Unterschied: NCS6K verwendet Virtualisierungstechnologie zum Aufbau des Systems. Jeder Knoten, Routing Processor (RP) oder Line Card (LC), kann mehrere virtuelle Systeme (VM) wie System Admin VM, IOS-XR VM1, IOS-XR VM2 usw. ausführen, die zusammen einen voll funktionsfähigen XR-Knoten bilden. Die folgende Abbildung zeigt ein Beispiel, in dem RP und LC eine IOS-XR-VM ausführen:
Abbildung 1
RPs und LCs können über ein Ethernet-Steuerungsnetzwerk miteinander verbunden werden. Der Steuerungsebenen-Datenverkehr zwischen RPs und LCs wird durch dieses Kontroll-Ethernet-Netzwerk geleitet. Da es sich um eine Virtualisierungsumgebung handelt, stellen sich Fragen wie die Bereitstellung dieses Pakets an eine bestimmte VM, und wie die Nicantic (NIC) in RP oder LC weiß, dass ein Paket für diese bestimmt ist.
Kurz gesagt: VLANs werden verwendet, um den Datenverkehr verschiedener VMs zu differenzieren. Dieser Prozess wird von der Netzwerkkarte durchgeführt. Abbildung 2 zeigt, wie die Netzwerkkarte VLAN 3074-Datenverkehr an die IOS-XR VM und VLAN 3073-Datenverkehr an die Admin VM übermittelt.
Abbildung 2
Wenn Sie diese Weiterleitungskomponente zusammenfassen, erhalten Sie einen vereinfachten Weiterleitungspfad für das Ping-Testszenario, wie in Abbildung 3 gezeigt.
Beim Durchführen eines Ping-Tests vom RP nehmen Pakete den folgenden Weiterleitungspfad innerhalb der Box:
RP_PING <—> RP_NETIO <—> RP_SPP <—> RP_Linux_Kernel_Socket <—> Switch <—> LC_FIA <—> LC_NPU (Include PSE, PLIM_ASIC) <—> Line

Für den Rest des Dokuments wird als Beispiel ein Szenario verwendet, in dem ein Ping vom RP initiiert wird. Der Ping-Befehl wird an einen direkt verbundenen Host auf Te0/0/0/2/0 initiiert. Die folgenden Schritte zeigen einen schrittweisen Ansatz für die Überprüfung des Ping-Pakets.

Der Zähler "show IPv4 traffic" (IPv4-Datenverkehr anzeigen) auf dem RP-Knoten zeigt an, wie viele ICMP-Echos (Internet Control Message Protocol) gesendet wurden und wie viele ICMP-Antworten zurückgegeben wurden.

Aktivieren Sie die Komponente Network Input Output (NETIO).
Der nächste Schritt besteht in der Überprüfung des RP FINT NETIO Kettenzählers. Sie müssen den "OUT"-Zähler des IPv4-Knotens in der Netzwerkkette sehen. Wenn sie erhöht wird, bedeutet dies, dass Pakete die NETIO-Komponente erreicht haben und von der NETIO-Komponente ausgesendet werden.
Check initial NETIO counter value.

Die Mgmtherschnittstelle in XR VM basiert auf dem IP-Stack von IOS-XR anstelle des IP-Stacks in Linux.
Für die Kommunikation mit Admin VM wird ether-vf1.3073 verwendet.
eher-vf1.3074 wird für den Datenverkehr auf Kontrollebene mit XR VM verwendet. Das Ping-Testpaket durchläuft diese Subschnittstelle (mithilfe des Linux-Netzwerkprotokoll-Stacks).
Tcpdump in Verbindung mit Linux hat viele Optionen, um interessanten Datenverkehr auszulagern. Darüber hinaus können Sie mit tcpdump-Tools den SDR-Verkehr (Secure Domain Router) auf Kontrollebene (VLAN 3074) ausspucken oder anderen Datenverkehr wie IPC-Kommunikation (Inter Process Communication) in VLAN 3073 aussparen.

Es ist empfehlenswert, dies im ersten Schritt zu überprüfen, aber in der Paketflusssequenz ist dies der letzte Schritt. Es hilft dabei herauszufinden, ob das Paket an die Leitung gesendet wurde und ob das Paket von der Leitung zurückgesendet wurde. Es kann helfen, das Problem einzugrenzen, ob es sich innerhalb oder außerhalb dieser Box befindet.
