Introduzione

In questo documento viene descritto come convalidare la programmazione e l'inoltro hardware di layer 2 sugli switch Catalyst serie 9400.

Prerequisiti

Requisiti

Nessun requisito specifico previsto per questo documento.

Componenti usati

Per la stesura del documento, sono stati usati switch Catalyst serie 9400 (UADP 2.0).

Nota: la versione software utilizzata in questo documento è la 16.6.1, ma deve essere mantenuta per le versioni più recenti di Cisco IOS-XE.

Nota: è possibile usare questo documento per altri tipi di switch Catalyst 9000, ma ignorare i comandi che fanno riferimento a una scheda di linea.

Le informazioni discusse in questo documento fanno riferimento a dispositivi usati in uno specifico ambiente di emulazione. Su tutti i dispositivi menzionati nel documento la configurazione è stata ripristinata ai valori predefiniti. Se la rete è operativa, valutare attentamente eventuali conseguenze derivanti dall'uso dei comandi.

Premesse

- Catalyst 9400 Supervisor1 (C9400-SUP-1) dispone di 3 ASIC di inoltro UADP 2.0 (0, 1, 2).

- Ogni ASIC di inoltro UADP 2.0 dispone di:

- Un dual-core (0, 1) - non esisteva nelle precedenti generazioni di ASICS UADP 2.0.

- SIF (Stack Interfaces) - utilizzato per connettersi agli altri 2 ASIC UADP 2.0 tramite un anello dello stack interno.

- NIF (Network Interfaces) - utilizzato per collegare una o più schede di linea tramite il backplane.

- Tutte le decisioni di inoltro dei pacchetti per le schede di linea e le interfacce uplink del Supervisor sono prese dai 3 ASIC di inoltro UADP 2.0 sul Supervisor attivo.

- Le schede di linea utilizzate in questo esempio dispongono di un ASIC stub single-core a 1 scheda di linea che non è coinvolto nelle decisioni di inoltro dei pacchetti.

- L'ASIC Line Card stub sulla scheda di linea si collega a 1 o più dei 3 ASIC di inoltro UADP 2.0 sul Supervisor tramite il backplane.

- I 3 ASIC di inoltro UADP 2.0 sul Supervisor prendono tutte le decisioni relative all'inoltro dei pacchetti.

Conteggio spostamenti MAC

Questo è il conteggio relativo allo spostamento (apprendimento) di un indirizzo MAC su una nuova interfaccia. Il conteggio degli spostamenti può avvenire quando un host terminale viene spostato fisicamente da un'interfaccia a un'altra, quando un host wireless esegue il roaming da un punto di accesso a un altro punto di accesso connesso a un'interfaccia diversa o quando il percorso dello spanning-tree cambia o si verifica un loop.

Programmazione hardware riuscita

Tutte le funzioni (indirizzo MAC, interfaccia, vlan e così via) vengono memorizzate nel database degli oggetti e programmate nell'hardware come oggetti.

L'RP programma l'FP, i programmi FP l'FED e infine il FED programma l'hardware ASIC di inoltro del Supervisor. Le voci software RP sono memorizzate come oggetti nel database degli oggetti, mentre le voci software FP sono memorizzate come oggetti asincroni nel database degli oggetti.

Quando il FP programma il FED (che a sua volta programma il Supervisor forwarding ASIC), il FED invia una conferma al FP. L'FP quindi lo inoltra all'RP per indicare che la programmazione hardware è stata completata correttamente. Se la programmazione dell'hardware FED è mancante o errata, è possibile utilizzare questo comando per verificare la presenza di problemi e/o riconoscimenti.

Se il comando precedente mostra oggetti diversi da zero in stato di problema in sospeso, utilizzare questo comando per trovare il numero di oggetto interessato:

C9400#show platform software object-manager fp active pending-issue-update

Utilizzare quindi questo comando per determinare il processo bloccato associato al numero dell'oggetto:

C9400#show platform software object-manager fp active object {object#}

Sul lato RP, utilizzare questo comando per verificare la presenza di un oggetto in sospeso (In attesa di eliminazione) non riconosciuto dal FP.

Statistiche supervisore - Percorso dati da supervisore a scheda di linea

Controllare le statistiche ASIC di inoltro di Supervisor UADP 2.0 attive associate a un'interfaccia del pannello anteriore specifica. nell'esempio viene usata l'interfaccia Gig1/0/13.

Esempio di output:

- Verificare quali interfacce della scheda di linea fanno parte dello stesso gruppo di porte.

- Ogni gruppo di porte ha condiviso 8 Gb/s di larghezza di banda dall'ASIC di stub della scheda di linea all'ASIC di inoltro del Supervisor.

- Ciascun gruppo di porte è associato a una SLI (System Link Interface) sull'ASIC dello stub della scheda di linea verso l'ASIC di inoltro del Supervisor.

Statistiche scheda di linea - Percorso dati da supervisore a scheda di linea

Controllare le statistiche ASIC Line card stub Card associate a un'interfaccia del pannello anteriore specifica. Nell'esempio, l'interfaccia Gig1/0/13 è l'elemento attivo.

Esempio di output:

- Pacchetti ricevuti da Gig 1/0/13, accedere alla porta di ricezione dell'interfaccia di rete e passare attraverso IQS all'interfaccia dello stack.

- Da qui, un pacchetto può uscire dall'interfaccia dello stack per un altro Supervisor ASIC o tornare indietro attraverso SQS, AQM, EQC, ESM, RWE, e quindi uscire dalla trasmissione dell'interfaccia di rete di Gig 1/0/13.

- I pacchetti inviati da altre interfacce ASIC Supervisor che escono da Gig 1/0/13 entrano in Sif e quindi passano attraverso SQS, AQM, EQC, ESM, RWE e quindi escono da NifTx di Gig 1/0/13.

- Per AQM ci sono 8 code Tx. Se vengono visualizzate le eliminazioni da queste code, è possibile utilizzare questo comando per determinare quale delle code sta riscontrando le eliminazioni: show platform hardware feed active va in coda statistiche interfaccia Gig 1/0/13

Controllare lo stato del controllo del flusso dalla prospettiva di una scheda di linea per l'interfaccia del pannello anteriore. Ciò aiuta a identificare eventuali congestioni sull'interfaccia.

- I valori sono "-" quando non è presente alcun controllo del flusso; in caso contrario, è indicato il numero della coda che ha sperimentato il controllo del flusso (congestione).

- Il controllo del flusso ricevuto dall'interfaccia viene passato dall'ASIC scheda linea sulla scheda di linea all'ASIC Supervisor sul Supervisor, dove le perdite AQM vengono in genere visualizzate sull'ASIC Supervisor. L'OCI (Out-of-band Control Interface) è il canale di comunicazione interno tra la scheda di linea e il Supervisor attivo utilizzato per segnalare il controllo del flusso dalla scheda di linea al Supervisor.

Verificare che il traffico di controllo scorra da una prospettiva ASIC Line Card Stub tra l'ASIC Line Card Stub sulla scheda Line e l'ASIC Supervisor forwarding sui supervisori attivi e in standby tramite le interfacce OCI.

- OCI = Out-of-band Control Interface = canali di comunicazione interni tra la scheda di linea e i supervisori attivi e in standby

Verificare quali interfacce della scheda di linea fanno parte dello stesso gruppo di porte che condivide 8 Gb/s di larghezza di banda dall'ASIC dello stub della scheda di linea verso l'ASIC di inoltro del Supervisor attivo. Ciascun gruppo di porte è associato a una della SLI (System Link Interface) sull'ASIC dello stub della scheda di linea verso il Supervisor.
