Contenido
Introducción
Este documento describe cómo validar la programación de hardware de Capa 2 y el reenvío en switches Catalyst serie 9400.
Prerequisites
Requirements
No hay requisitos específicos para este documento.
Componentes Utilizados
La información de este documento se basa en el switch Catalyst serie 9400 (UADP 2.0).
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. Si tiene una red en vivo, asegúrese de entender el posible impacto de cualquier comando.
Antecedentes
- El Catalyst 9400 Supervisor1 (C9400-SUP-1) tiene 3 ASIC de reenvío UADP 2.0 (0, 1, 2).
- Cada ASIC de reenvío UADP 2.0 tiene:
- Núcleo dual (0, 1): esto no existía en las generaciones anteriores de ASICS UADP 2.0.
- SIF (interfaces de pila): se utiliza para conectarse a los otros 2 ASIC UADP 2.0 mediante un anillo de pila interno.
- NIFs (Interfaces de red): se utiliza para conectarse a 1 o más tarjetas de línea a través de la placa de interconexiones.
- Todas las decisiones de reenvío de paquetes para las tarjetas de línea y las interfaces de link ascendente del supervisor son tomadas por los 3 ASIC de reenvío UADP 2.0 en el Supervisor activo.
- Las tarjetas de línea utilizadas en este ejemplo tienen 1 ASIC de stub de núcleo único de tarjeta de línea que no participa en las decisiones de reenvío de paquetes.
- El ASIC stub de tarjeta de línea en la tarjeta de línea se conecta a 1 o más de los 3 ASIC de reenvío UADP 2.0 en el Supervisor a través de la placa de interconexiones.
- Los 3 ASIC de reenvío UADP 2.0 en el Supervisor toman todas las decisiones de reenvío de paquetes.

Programación de hardware correcta
Todas las funciones (ya sean una dirección mac, una interfaz, una vlan, etc.) se almacenan en la base de datos de objetos y se programan en el hardware como objetos.
El RP programa el FP, el FP programa la FED y la FED finalmente programa el hardware ASIC de reenvío de Supervisor. Las entradas de software RP se almacenan como objetos en la base de datos de objetos y las entradas de software FP se almacenan como objetos asincrónicos en la base de datos de objetos.
Cuando el FP programa la FED (que a su vez programa el ASIC de reenvío del supervisor), la FED envía un reconocimiento de vuelta al FP. El FP luego lo reenvía al RP para indicar que la programación de hardware se completó correctamente. Si falta la programación de hardware FED o es incorrecta, puede utilizar este siguiente comando para comprobar si hay problemas o confirmaciones.
C9400#show platform software object-manager fp active statistics Forwarding Manager Asynchronous Object Manager Statistics Object update: Pending-issue: 0, Pending-acknowledgement: 0 Batch begin: Pending-issue: 0, Pending-acknowledgement: 0 Batch end: Pending-issue: 0, Pending-acknowledgement: 0 Command: Pending-acknowledgement: 0 Total-objects: 3269 Stale-objects: 0 Resolve-objects: 0 Error-objects: 0 Paused-types: 0
Si el comando anterior muestra objetos que no son cero en estado de problema pendiente, utilice este comando para encontrar el número de objeto involucrado:
C9400#show platform software object-manager fp active pending-issue-update
A continuación, utilice este comando para determinar el proceso atascado asociado con el número de objeto:
C9400#show platform software object-manager fp active object {object#}
En el lado RP, utilice este comando para comprobar si hay eliminación pendiente (Del Pend) para un objeto que el FP no reconoció.

Estadísticas de tarjeta de línea - Ruta de datos de supervisor a tarjeta de línea
Verifique las estadísticas ASIC stub de tarjeta de línea asociadas a una interfaz específica del panel frontal. En este ejemplo, la interfaz Gig1/0/13 es el foco.
Ejemplo de salida:
-
Los paquetes recibidos de Gig 1/0/13, ingresan al puerto de recepción de la interfaz de red y avanzan a través de IQS a la interfaz de pila.
-
A partir de ahí, un paquete sale de la interfaz de pila a otro Supervisor ASIC , o regresa a través de SQS, AQM, EQC, ESM, RWE, y luego sale de la transmisión de la interfaz de red de Gig 1/0/13.
-
Los paquetes enviados desde otras interfaces de Supervisor ASIC que salen de Gig 1/0/13 ingresan Sif y luego pasan a través de SQS, AQM, EQC, ESM, RWE y luego salen del NifTx de Gig 1/0/13.
-
Para AQM hay 8 colas Tx. Si ve caídas de estas colas, puede utilizar este comando para determinar cuál de las colas está experimentando caídas: show platform hardware fed active go queue stats interface Gig 1/0/13

Verifique el estado del control de flujo desde una perspectiva de tarjeta de línea para la interfaz del panel frontal. Esto ayuda a identificar cualquier congestión en la interfaz.
- Los valores son "-" cuando no hay ningún control de flujo, de lo contrario se indica el número de cola que experimenta control de flujo (congestión).
- El control de flujo recibido por la interfaz se pasa de la tarjeta de línea ASIC en la tarjeta de línea al Supervisor ASIC en el Supervisor donde las caídas de AQM se suelen ver en el Supervisor ASIC. El OCI (interfaz de control fuera de banda) es el canal de comunicación interno entre la tarjeta de línea y el supervisor activo que se utiliza para indicar el control de flujo de la tarjeta de línea al supervisor.
