Validierung der Layer-2-Hardware auf Catalyst Switches der Serie 9000
Inhalt
Einleitung
In diesem Dokument wird beschrieben, wie die Layer-2-Hardwareprogrammierung und -weiterleitung für Catalyst Switches der Serie 9400 validiert wird.
Voraussetzungen
Anforderungen
Es gibt keine spezifischen Anforderungen für dieses Dokument.
Verwendete Komponenten
Die Informationen in diesem Dokument basieren auf Switches der Catalyst Serie 9400 (UADP 2.0).
Die Informationen in diesem Dokument beziehen sich auf Geräte in einer speziell eingerichteten Testumgebung. Alle Geräte, die in diesem Dokument benutzt wurden, begannen mit einer gelöschten (Nichterfüllungs) Konfiguration. Wenn Ihr Netzwerk in Betrieb ist, stellen Sie sicher, dass Sie die möglichen Auswirkungen aller Befehle kennen.
Hintergrundinformationen
Der Catalyst 9400 Supervisor1 (C9400-SUP-1) verfügt über drei UADP 2.0 Forwarding ASICs (0, 1, 2).
Jeder UADP 2.0 Forwarding-ASIC verfügt über:
- Ein Dual-Core (0, 1) - dies gab es in früheren Generationen von UADP 2.0 ASICS nicht.
- SIFs (Stack Interfaces) - werden verwendet, um über einen internen Stack-Ring eine Verbindung zu den anderen beiden UADP 2.0 ASICs herzustellen.
- NIFs (Network Interfaces) - werden für die Verbindung mit einer oder mehreren Linecards über die Backplane verwendet.
- Alle Entscheidungen bezüglich der Paketweiterleitung für die Linecards und die Supervisor-Uplink-Schnittstellen werden von den drei UADP 2.0-Weiterleitungs-ASICs auf dem aktiven Supervisor getroffen.
- Die in diesem Beispiel verwendeten Linecards verfügen über einen Single-Core-Stub-ASIC mit 1 Linecard, der nicht an Entscheidungen zur Paketweiterleitung beteiligt ist.
- Der Linecard-Stub-ASIC auf der Linecard ist über die Rückwandplatine mit mindestens einem der drei UADP 2.0-Weiterleitungs-ASICs auf dem Supervisor verbunden.
- Die drei UADP 2.0-Weiterleitungs-ASICs auf dem Supervisor treffen alle Entscheidungen bezüglich der Paketweiterleitung.

Erfolgreiche Hardwareprogrammierung
Alle Funktionen (ob MAC-Adresse, Schnittstelle, VLAN usw.) werden in der Objektdatenbank gespeichert und als Objekte in die Hardware programmiert.
Der RP programmiert das FP, das FP programmiert das FED und das FED programmiert dann schließlich die Supervisor Forwarding ASIC-Hardware. RP-Softwareeinträge werden als Objekte in der Objektdatenbank und die FP-Softwareeinträge als asynchrone Objekte in der Objektdatenbank gespeichert.
Wenn das FED das FED programmiert (das wiederum den Supervisor Forwarding ASIC programmiert), sendet das FED eine Bestätigung zurück an das FP. Das FP leitet es dann an den RP weiter, um anzugeben, dass die Hardwareprogrammierung erfolgreich abgeschlossen wurde. Wenn die Programmierung der FED-Hardware fehlt oder falsch ist, können Sie mit diesem nächsten Befehl auf Probleme und/oder Bestätigungen überprüfen.

Wenn der vorherige Befehl Objekte anzeigt, die nicht null sind und sich im Zustand "Ausstehend" befinden, suchen Sie mit diesem Befehl nach der betreffenden Objektnummer:
C9400#show platform software object-manager fp active pending-issue-update
Verwenden Sie dann diesen Befehl, um den fixierten Prozess zu bestimmen, der mit der Objektnummer verknüpft ist:
C9400#show platform software object-manager fp active object {object#}
Verwenden Sie auf RP-Seite diesen Befehl, um ausstehende Löschvorgänge (Del Pend) für ein Objekt zu überprüfen, das vom RP nicht bestätigt wurde.

Supervisor-Statistik - Datenpfad zwischen Supervisor und Line Card
Überprüfen Sie die aktiven Supervisor UADP 2.0 Forwarding ASIC-Statistiken, die einer bestimmten Frontblendenschnittstelle zugeordnet sind. In diesem Beispiel wird die Schnittstelle Gig1/0/13 verwendet.
Ausgabebeispiel:
- Prüfen Sie, welche Schnittstellen der Linecard zur gleichen Portgruppe gehören.
- Jede Portgruppe nutzt 8 Gbit/s an Bandbreite vom Linecard-Stub-ASIC zum Supervisor Forwarding-ASIC.
- Jede Portgruppe ist mit einem SLI (System Link Interface) auf dem Line Card Stub-ASIC verbunden, der zum Supervisor Forwarding-ASIC führt.

Linecard-Statistik - Datenpfad zwischen Supervisor und Linecard
Überprüfen Sie die Line Card Line Card Stub-ASIC-Statistiken, die einer bestimmten Frontblendenschnittstelle zugeordnet sind. In diesem Beispiel steht die Schnittstelle Gig1/0/13 im Mittelpunkt.
Ausgabebeispiel:
-
Pakete, die von Gig 1/0/13 empfangen werden, gelangen in den Empfangsport der Netzwerkschnittstelle und gelangen über IQS zur Stack-Schnittstelle.
-
Von dort geht ein Paket entweder über die Stack-Schnittstelle an einen anderen Supervisor ASIC oder über den SQS, AQM, EQC, ESM, RWE zurück und geht dann über die Netzwerkschnittstellen-Übertragung von Gig 1/0/13.
-
Pakete, die von anderen Supervisor-ASICs-Schnittstellen gesendet werden, die aus Gig 1/0/13 ausgehen, gelangen in Sif und passieren dann SQS, AQM, EQC, ESM, RWE und gehen dann die NifTx von Gig 1/0/13 aus.
-
Für AQM gibt es 8 Tx-Warteschlangen. Wenn Sie Drops aus diesen Warteschlangen sehen, können Sie diesen Befehl verwenden, um festzustellen, welche Warteschlange ein Drops aufweist: show platform hardware fed active goes queue stats interface Gig 1/0/13

Überprüfen Sie den Status der Flusssteuerung aus der Line Card-Perspektive für die Frontblendenschnittstelle. So können Überlastungen an der Schnittstelle leichter erkannt werden.
- Werte sind "-", wenn keine Flusssteuerung vorhanden ist, andernfalls wird die Warteschlangennummer mit Flusssteuerung (Überlastung) angezeigt.
- Die von der Schnittstelle empfangene Flusskontrolle wird vom Linecard-ASIC auf der Linecard an den Supervisor-ASIC auf dem Supervisor weitergeleitet, wo AQM-Drops typischerweise auf dem Supervisor-ASIC zu sehen sind. Die OCI (Out-of-Band Control Interface) ist der interne Kommunikationskanal zwischen der Linecard und dem aktiven Supervisor, der zur Signalisierung der Flusssteuerung von der Linecard zum Supervisor verwendet wird.
