Componenti usati

Le informazioni fornite in questo documento si basano sulle seguenti versioni software e hardware:

• 9800 modello WLC
• Cisco IOS XE versione 17.15.5
• Serie 9100 AP Model
  
  

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.

Panoramica sullo scenario di ancoraggio esterno

• Controller esterno: Questo WLC gestisce il layer 2 o il lato wireless della rete. Ha dei punti di accesso connessi e tutto il traffico dei client per le WLAN ancorate viene incapsulato nel tunnel della mobilità e inviato al controller di ancoraggio. Il traffico non esiste localmente nel controller esterno.
• Controller di ancoraggio: Questo serve come punto di uscita di livello 3. Riceve il traffico del client tramite il tunnel della mobilità dai controller esterni e decapsula o termina il traffico del client nel punto di uscita (VLAN). In questa posizione i client vengono visualizzati nella rete.

I punti di accesso sul WLC esterno trasmettono gli SSID WLAN e hanno un tag di policy assegnato che collega il profilo WLAN al profilo di policy appropriato. Quando un client wireless si connette a questo SSID, il controller esterno invia sia il nome SSID che il profilo dei criteri come parte delle informazioni client al WLC di ancoraggio. Al momento della ricezione, il WLC di ancoraggio controlla la propria configurazione in modo che corrisponda al nome dell'SSID e al nome del profilo dei criteri. Quando Anchor WLC trova una corrispondenza, applica la configurazione corrispondente e fornisce un punto di uscita per il client wireless. Pertanto, è obbligatorio che i nomi e le configurazioni del profilo della WLAN e delle policy corrispondano sui WLC esteri e ancorati alla WLC 9800, con l'eccezione della VLAN in Policy Profile.

Topologia

Configurazione di un'ancora esterna tra 9800 WLC

WLAN con autenticazione di layer 2

Requisiti di configurazione 

1. Verificare che il nome e la configurazione della WLAN siano identici sui WLC esterni e di ancoraggio e che sia configurata per l'autenticazione di layer 2 (PSK o 802.1x).
2. Creare un profilo criteri con lo stesso nome sui WLC esterni e ancorati con la stessa configurazione.
3. Sul WLC esterno, configurare il mapping del WLC di ancoraggio all'interno del rispettivo profilo criteri.
4. Sul WLC di ancoraggio, configurare il profilo dei criteri per designare il controller come ancoraggio di esportazione.
5. Sul WLC esterno, mappare la WLAN al profilo della policy appropriato utilizzando un codice di matricola.

Flusso per SSID basato su ancoraggio esterno di livello 2

1. Il client avvia una connessione al SSID trasmesso dal WLC esterno. Il WLC esterno esegue l'autenticazione di layer 2, convalidando le credenziali localmente o tramite un server AAA esterno, a seconda dei criteri di sicurezza configurati.
2. Una volta completata l'autenticazione, la sessione client viene ancorata al WLC di ancoraggio. Al client viene assegnato un indirizzo IP e viene eseguita la transizione allo stato RUN sul WLC di ancoraggio.
3. Una volta stabilita la sessione, tutto il traffico di dati dei client viene tunneling dal WLC esterno al WLC di ancoraggio, dove viene reindirizzato alla rete.

Acquisizione pacchetti

Il client invia una richiesta di associazione ed esegue l'autenticazione di layer 2, gestita dal controller esterno.

Associazione client + traffico di autenticazione di livello 2

 Viene attivato un handoff di mobilità tra i controller esteri e ancorati tramite la porta UDP 16667. Se un evento di mobilità ha esito positivo, lo stato del client passa a ESEGUI con un ruolo Esporta esterno.
Il controller esterno riceve il traffico DHCP del client tramite il tunnel CAPWAP e lo inoltra al controller di ancoraggio per un'ulteriore elaborazione.

Il traffico DHCP client ricevuto sul controller esterno viene inoltrato al controller di ancoraggio tramite il tunnel della mobilità

Acquisizione pacchetto su ancoraggio

Dopo il passaggio della mobilità, il controller di ancoraggio riceve il traffico DHCP dal controller esterno tramite il tunnel della mobilità.
Al completamento del processo DORA, il client entra in stato RUN con un ruolo Export Anchor. Da questo punto in avanti, il controller di ancoraggio funge da punto di uscita per il traffico di dati del client.

Autenticazione Web locale

Flusso per SSID autenticazione Web locale nell'installazione dell'ancoraggio esterno

1. Il client avvia una connessione al SSID annunciato dal WLC esterno.
2. Poiché non viene eseguita alcuna autenticazione di layer 2, il client viene immediatamente ancorato al WLC di ancoraggio. Il client entra in stato RUN sul WLC esterno, con il ruolo di mobilità designato come Esporta esterno.
3. Il client ottiene un indirizzo IP e viene reindirizzato a una pagina Web. Questo traffico viene gestito dal controller di ancoraggio.
4. Una volta completata l'autenticazione sul portale, il client passa allo stato RUN sul WLC di ancoraggio, con il ruolo di ancoraggio di esportazione.

Acquisizione pacchetti

Il client invia una richiesta di associazione, che viene gestita dal controller esterno.

Fase di associazione client con controller esterno

Viene attivato un handoff di mobilità tra i controller esteri e ancorati tramite la porta UDP 16667. Se un evento di mobilità ha esito positivo, lo stato del client passa a ESEGUI con un ruolo Esporta esterno.
Il controller esterno riceve il traffico DHCP del client tramite il tunnel CAPWAP e lo inoltra al controller di ancoraggio per un'ulteriore elaborazione.

Il traffico DHCP client ricevuto sul controller esterno viene inoltrato al controller di ancoraggio tramite il tunnel della mobilità

Analogamente, il client invia lo stato della connettività di rete e il traffico di controllo dell'accesso alla pagina Web al WLC esterno tramite il tunnel CAPWAP; il WLC esterno lo inoltra al WLC di ancoraggio utilizzando il tunnel per la mobilità, dove il controller di ancoraggio intercetta o elabora il traffico.

Acquisizione pacchetti

Dopo il passaggio della mobilità, il controller di ancoraggio riceve il traffico DHCP dal controller esterno tramite il tunnel della mobilità. 

Traffico DHCP client su controller di ancoraggio ricevuto da controller esterno

Il controller di ancoraggio riceve i controlli di connettività, le richieste di accesso alle pagine Web e i dettagli di autenticazione per continuare l'elaborazione.

Controllo dello stato della connettività di rete sul controller di ancoraggio

Reindirizza URL inviato al client

Pagina Accesso client a autenticazione Web locale per fornire i dettagli di autenticazione

Una volta completata correttamente l'autenticazione Web locale, il client passa allo stato RUN con un ruolo di ancoraggio di esportazione. Da questo punto in avanti, il controller di ancoraggio funge da punto di uscita per il traffico di dati del client.

Autenticazione Web centrale

Flusso per SSID autenticazione Web centrale nell'impostazione dell'ancoraggio esterno

1. Il client invia una richiesta di associazione per il SSID trasmesso dal controller WLC (Foreign Wireless LAN Controller).
2. Il WLC esterno esegue il filtro MAC inviando una richiesta di accesso al server RADIUS. Il server RADIUS risponde con un comando Access-Accept, che include l'URL di reindirizzamento e l'elenco di controllo di accesso (ACL) necessari.
3. Il WLC esterno invia la risposta dell'associazione al client.
4. Il client è ancorato al WLC di ancoraggio. Il client entra nello stato RUN sul WLC esterno, con il ruolo mobility impostato su Export Foreign.
5. Il client ottiene un indirizzo IP. In questa fase, il WLC di ancoraggio gestisce il traffico di reindirizzamento, indirizzando il client al portale di autenticazione.
6. Una volta reindirizzato, il client comunica direttamente con il server RADIUS. Il traffico viene tunneling attraverso il WLC di ancoraggio verso il server RADIUS.
7. Il client immette le credenziali di autenticazione nel server RADIUS. Una volta completata l'autenticazione, il server RADIUS invia una richiesta di modifica dell'autorizzazione (CoA) al WLC esterno.
8. Il WLC esterno invia una risposta di CoA al server RADIUS. Il client passa allo stato RUN sul WLC di ancoraggio, con il ruolo impostato su Export Anchor.
9. Tutto il traffico client successivo viene tunneling dal WLC esterno al WLC di ancoraggio, dove esce dalla rete.

Diagramma di flusso della connettività client per SSID autenticazione Web centrale in configurazione ancoraggio esterno

Analisi del flusso SSID Webauth centrale nella configurazione dell'ancoraggio esterno tramite i log

In questa sezione viene illustrato il flusso della connettività client per l'SSID di autenticazione Web centrale tramite la traccia radioattiva (RA Trace), l'EPC (Embedded Packet Capture) e lo stato del client sia sul controller esterno che sul controller di ancoraggio.

Acquisizione pacchetti

Il client invia una richiesta di associazione ed esegue l'autenticazione MAC. Questo traffico viene gestito dal controller esterno.

Fase associazione client su controller esterno con MAB wireless

Viene attivato un handoff di mobilità tra i controller esteri e ancorati tramite la porta UDP 16667. Se un evento di mobilità ha esito positivo, lo stato del client passa a ESEGUI con un ruolo Esporta esterno.

Il controller esterno riceve il traffico DHCP del client tramite il tunnel CAPWAP e lo inoltra al controller di ancoraggio per un'ulteriore elaborazione.

Il traffico DHCP client ricevuto sul controller esterno viene inoltrato al controller di ancoraggio tramite il tunnel della mobilità

Analogamente, il client invia lo stato della connettività di rete e il traffico di controllo dell'accesso alla pagina Web al WLC esterno tramite il tunnel CAPWAP; il WLC esterno lo inoltra al WLC di ancoraggio utilizzando il tunnel per la mobilità, dove il controller di ancoraggio intercetta o elabora il traffico.

Controllo stato connettività di rete su controller esterno

Reindirizza URL inviato al client

Accesso client alla pagina WebAuth centrale per fornire i dettagli di autenticazione

Il controller esterno elabora la richiesta CoA dopo la riuscita autenticazione Web centrale.

Dopo il passaggio della mobilità, il controller di ancoraggio riceve il traffico DHCP dal controller esterno tramite il tunnel della mobilità.

Traffico DHCP client su controller di ancoraggio ricevuto da controller esterno

Il controller di ancoraggio riceve i controlli di connettività, le richieste di accesso alle pagine Web e i dettagli di autenticazione per continuare l'elaborazione.

Controllo dello stato della connettività di rete sul controller di ancoraggio

Reindirizza URL inviato al client

Pagina Accesso client a autenticazione Web locale per fornire i dettagli di autenticazione

Quando l'autenticazione Web centrale ha esito positivo, viene attivato il processo di modifica dell'autorizzazione (CoA). Dopo un'operazione di CoA riuscita, il client passa allo stato RUN con un ruolo di ancoraggio di esportazione.

Autenticazione Web esterna

Flusso per SSID Webauth esterno nell'installazione di una porta esterna

1. Il client avvia una connessione al SSID trasmesso dal WLC esterno.
2. Poiché non è richiesta l'autenticazione di layer 2, il client è ancorato al WLC di ancoraggio. Il client passa allo stato RUN sul WLC esterno, con il ruolo di mobilità designato come Esporta esterno.
3. Il client acquisisce un indirizzo IP. Il WLC di ancoraggio intercetta il traffico e reindirizza il client al portale del server Web esterno, come definito nei parametri di autenticazione Web.
4. Il client invia le credenziali di autenticazione tramite il portale. Queste credenziali vengono convalidate localmente sul WLC o tramite un server di autenticazione esterno, a seconda dei criteri di sicurezza configurati.
5. Una volta completata l'autenticazione, il client passa allo stato RUN sul WLC di ancoraggio, assumendo il ruolo di ancoraggio di esportazione.
6. Dopo aver completato l'autenticazione, tutto il traffico client successivo viene tunneling dal WLC esterno al WLC di ancoraggio, dove esce dalla rete.

Acquisizione pacchetti

Il client invia una richiesta di associazione, che viene gestita dal controller esterno.

Fase di associazione client con controller esterno

Viene attivato un handoff di mobilità tra i controller esteri e ancorati tramite la porta UDP 16667. Se un evento di mobilità ha esito positivo, lo stato del client passa a ESEGUI con un ruolo Esporta esterno.
Il controller esterno riceve il traffico DHCP del client tramite il tunnel CAPWAP e lo inoltra al controller di ancoraggio per un'ulteriore elaborazione.

Il traffico DHCP client ricevuto sul controller esterno viene inoltrato al controller di ancoraggio tramite il tunnel della mobilità

Analogamente, il client invia lo stato della connettività di rete e il traffico di controllo dell'accesso alla pagina Web al WLC esterno tramite il tunnel CAPWAP; il WLC esterno lo inoltra al WLC di ancoraggio utilizzando il tunnel per la mobilità, dove il controller di ancoraggio intercetta o elabora il traffico.

Controllo stato connettività di rete su controller esterno

Reindirizza URL inviato al client

Accesso client alla pagina WebAuth esterna per fornire i dettagli di autenticazione

Acquisizione pacchetti

Dopo il passaggio della mobilità, il controller di ancoraggio riceve il traffico DHCP dal controller esterno tramite il tunnel della mobilità. 

Traffico DHCP client su controller di ancoraggio ricevuto da controller esterno

Il controller di ancoraggio riceve i controlli di connettività, le richieste di accesso alle pagine Web e i dettagli di autenticazione per continuare l'elaborazione.

Controllo dello stato della connettività di rete sul controller di ancoraggio

Reindirizza URL inviato al client

Il client invia le credenziali di autenticazione tramite il portale. Queste credenziali vengono convalidate localmente sul WLC o tramite un server di autenticazione esterno, a seconda dei criteri di sicurezza configurati.

Bilanciamento del carico tra più controller di ancoraggio

Quando si esegue il mapping di più controller di ancoraggio a una singola WLAN, la distribuzione del traffico dipende dalla priorità. È possibile configurare tre livelli di priorità: Principale, Secondario e Terziario. La funzione di priorità di ancoraggio guest fornisce un meccanismo per la distribuzione del carico attivo/standby tra i controller di ancoraggio. Ciò si ottiene assegnando una priorità fissa a ciascun controller di ancoraggio: il carico viene distribuito al controller con la priorità più alta e in modo round robin tra i controller che condividono lo stesso valore di priorità.

Mappatura della priorità di ancoraggio

Risoluzione dei problemi di connettività dei client nello scenario di ancoraggio esterno

1. Problemi di caricamento client
   1. Stato tunnel: Verificare che il tunnel di mobilità tra i controller esterni e di ancoraggio rimanga attivo.
   2. Configurazione non corrispondente: Verificare la parità di configurazione tra entrambi i controller. Le discrepanze nei nomi delle WLAN, nei nomi dei profili delle policy o nelle impostazioni avanzate, ad esempio l'override AAA, i requisiti DHCP IPv4 e il NAC, possono causare errori di mancata corrispondenza dei profili o di rifiuto di ancoraggio.
   3. Altro: Se il tunnel è attivo senza problemi di configurazione, l'approccio per la risoluzione dei problemi è simile al normale problema di connettività dei client e consente di controllare il rispettivo controller che gestisce il traffico interessato.
      
      
2. Connettività intermittente
   1. Tunnel Flap: Se i pacchetti keepalive tra i due controller non arrivano, il tunnel si blocca, impedendo al client di mantenere una connessione con l'SSID.
   2. Larghezza di banda bassa: Se la PMTU (Path MTU) tra peer mobili scende a un valore inferiore (576), le prestazioni dei client diminuiscono. Questo si verifica in genere quando i messaggi keepalive mtu del percorso non vengono visualizzati tra entrambi i peer mobilità
      
      

      Nota: Il controller con l'indirizzo MAC con mobilità inferiore avvia sia i messaggi keepalive standard che i messaggi keepalive MTU percorso.

3. Problemi specifici di accesso al sito Web
   1. Le intestazioni del traffico di mobilità includono gli identificatori dei gruppi di mobilità, gli indirizzi MAC, gli indirizzi IP e i pacchetti DTLS CAPWAP crittografati scambiati sulle porte UDP 1666 e 1667. Questo sovraccarico si aggiunge all'intestazione CAPWAP esistente. Nel caso del traffico TCP, dopo la regolazione del valore TCP MSS configurato per il punto di accesso, se le dimensioni del pacchetto superano la PMTU di mobilità (massimo 1385 byte) a causa di questo sovraccarico aggiuntivo, si verifica la frammentazione. Mentre la frammentazione è in genere gestita dalla rete, si verificano problemi se i pacchetti arrivano fuori servizio o in ritardo. Queste condizioni influiscono sul riassemblaggio dei pacchetti e determinano errori di accessibilità dei dati per siti Web specifici.

Raccolta registri da controller esterno e ancoraggio

1. Abilitare il timestamp del prompt di esecuzione dei termini per avere un riferimento temporale per tutti i comandi.
2. Utilizzare show tech-support wireless !! per rivedere la configurazione.
3. È possibile controllare lo stato del tunnel per la mobilità e visualizzare il riepilogo della mobilità wireless.
4. Le statistiche per Mobility Peer che includono lo stato del collegamento, i dati e gli eventi del client, le statistiche keep-alive mostrano l'ip peer mobilità wireless <IP>
5. Abilitare la traccia radioattiva per l'indirizzo IP/MAC del peer mobilità e l'indirizzo MAC del client.

   Via CLI:


   debug {MAC wireless | ip} {aaaa.bbbb.ccc | x.x.x.x } {tempo-monitor} {N secondi} !! L'impostazione della durata consente di attivare le tracce per un massimo di 24 giorni.

   nessun {MAC} wireless di debug | ip} {aaaa.bbbb.ccc | x.x.x!! Per disattivare il debug
   
   WLC genera un file di traccia di debug con Client_info, comando per controllare se il file di traccia di debug è stato generato con dir bootflash: | esegui il debug!!

   

   Avviso: Il debug condizionale abilita la registrazione a livello di debug che a sua volta aumenta il volume dei log generati. Se si lascia attiva questa opzione, si riduce il tempo di visualizzazione dei log. Si consiglia pertanto di disattivare sempre il debug al termine della sessione di risoluzione dei problemi.

6. Per disabilitare tutte le operazioni di debug, eseguire i seguenti comandi:

   # cancellazione di tutte le condizioni della piattaforma !!

   # undebug all !!
   Tramite GUI:



   Passaggio 1. Passare a Risoluzione dei problemi > Traccia radioattiva.

   Passaggio 2. Fare clic su Add (Aggiungi) e immettere un indirizzo MAC/IP Mobility Peer o un indirizzo MAC client che si desidera risolvere.
   Passaggio 3. Quando si è pronti per avviare il rilevamento radioattivo, fare clic su Start (Avvia). Una volta avviato, il log di debug viene scritto su disco in relazione a qualsiasi elaborazione del control plane correlata agli indirizzi MAC tracciati.
   Passaggio 4. Quando si riproduce il problema che si desidera risolvere, fare clic su Stop.
   Passaggio 5. Per ogni indirizzo MAC sottoposto a debug, è possibile generare un file di log che fascicola tutti i log relativi a tale indirizzo MAC facendo clic su Genera.
   Passaggio 6. Scegliere il periodo di tempo che deve trascorrere prima che il file di log fascicolato venga completato e fare clic su Applica al dispositivo.
   Passaggio 7. È ora possibile scaricare il file facendo clic sull'icona piccola accanto al nome del file. Questo file è presente nell'unità flash di avvio del controller e può anche essere copiato dalla CLI.

7. Acquisizioni incorporate 


Via CLI:
cattura monitor MYCAP cancellata!!
il monitor acquisisce l'interfaccia MYCAP Po1!!
monitoraggio acquisizione buffer MYCAP dimensione 100 !!
monitor capture MYCAP match access-list name !! (se si tiene traccia del traffico del tunnel di mobilità tra WLC)
