Converged Access Controller/NGWC AP Join Risoluzione dei problemi con Traces

Introduzione

In questo documento vengono descritti i comandi di traccia utilizzati per risolvere i problemi di join dei punti di accesso (AP, Access Point) nei controller di accesso convergenti e vengono descritte alcune delle cause più comuni dell'errore di join dei punti di accesso.

Prerequisiti

Requisiti

Cisco raccomanda la conoscenza di base dei seguenti argomenti:

• Protocollo LWAPP (Lightweight Access Point Protocol)/Controllo e provisioning di punti di accesso wireless (CAPWAP)
• Configurazioni LAP (Lightweight Access Point) e WLC (Wireless LAN Controller) per operazioni di base

Componenti usati

Per la stesura del documento, è stato usato uno switch Cisco Catalyst serie 3850 con software versione 3.3.0 SE.

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.

Prodotti correlati

Questo documento è applicabile a tutti i controller degli accessi convergenti.

• Cisco serie 5760 Wireless Controller
• Switch Cisco Catalyst serie 3560
• Switch Cisco Catalyst serie 3850

Risoluzione dei problemi

Operazioni di base

Per risolvere il problema di aggiunta dell'access point sui controller di accesso convergenti, attenersi alla seguente procedura:

1. Confermare che l'access point sia in grado di estrarre un indirizzo IP. Dallo switch a cui è collegato l'access point, immettere:
   

   #show cdp neighbor  
            detail

   
   

   Nota: Per gli switch Catalyst serie 3850, l'access point deve essere collegato direttamente allo switch Catalyst serie 3850 e la configurazione della porta dello switch deve essere:
   
   Interfaccia gig <>
   Accesso in modalità switchport
   Switchport access vlan x >> dove x è l'interfaccia di gestione wireless vlan x configurata sugli switch Catalyst serie 3850.

   
   
   
2. Verificare che il WLC possa eseguire il ping dell'indirizzo IP e viceversa.
   
   
3. Verificare che nella rete sia configurato un controller di mobilità wireless. Se è stato eseguito l'accesso a un agente di mobilità, verificare che il controller di mobilità del tunnel sia attivo.
   

   #show wireless mobility summary

   
   
   
4. Verificare che la licenza AP sia abilitata sul MC:
   

   #show license right-to-use summary

   
   
   
5. Confermare che il codice paese appropriato è abilitato:
   

   #show wireless country configured 

Tracce dal controller

Una volta implementata la configurazione corretta, se l'access point ha esito negativo, è possibile utilizzare i comandi di traccia per un'ulteriore diagnosi. Questi comandi di traccia sono disponibili sul controller per la risoluzione dei problemi di CAPWAP e AP Join:

• #Set trace capwap
• #Set trace capwap ap
• #Set trace group-ap

In base all'analisi degli output della traccia, le tracce dell'access point del gruppo hanno fornito un output più pertinente per la risoluzione dei problemi del join AP. Pertanto, questa traccia (non filtrata) viene descritta in dettaglio in questo documento. Fare riferimento alla sezione Suggerimenti tecnici generali di questo documento per ulteriori informazioni sulle opzioni di filtro e le limitazioni per questa traccia.

Nota: L'output di esempio (filtrato e non filtrato) per capwap e capwap ap è incluso come riferimento.

• Per visualizzare le impostazioni predefinite della traccia, immettere:
  

  #show trace settings group-ap
  Buffer Properties:
  Feature-Name                                                                      Size        Level
  --------------------------------------------------------------------------------------------------------
  capwap/ap/event                                                                   0           warning
  dtls/ap/event                                                                     0           warning

        Filters: None
  Feature-Name: dtls/ap/event
        Filters: None
  Feature-Name: iosd-wireless/capwap
        Filters: None

  
  

  Nota: Per impostazione predefinita, non vi sono filtri impostati su nessuna traccia.

  
  
  
• Per cancellare il buffer di traccia che corrisponde alla traccia di group-ap, immettere:
  

  #set trace control group-ap clear

  
  
  
• Per impostare il livello di traccia per la traccia di group-ap, immettere:
  

  #set trace group-ap level ?
   debug    Debug-level messages (7)
    default  Unset Trace Level Value
    err      Error conditions (3)
    info     Informational (6)
    warning  Warning conditions (4)

  
  Utilizzare il debug #set trace group-ap level durante la risoluzione dei problemi.
  
  
• Per verificare il livello di traccia, immettere:
  

  # show trace settings group-ap

Motivi comuni per l'errore di aggiunta dell'access point

In questa sezione vengono descritte le cause comuni degli errori di join AP.

Problema 1: L'access point sugli switch Catalyst serie 3850 non è nella VLAN di gestione wireless.

 #show run interface gig1/0/2

interface GigabitEthernet1/0/22
 description AP
 switchport access vlan 25
 switchport mode access

#show run | inc wireless

 L'access point è nella VLAN 25 e non è presente una configurazione dell'interfaccia di gestione wireless per la VLAN 25.

Problema 2: Modello AP non supportato.

Ecco un test per AP1131.

Problema 3: La licenza per il conteggio dei punti di accesso non è abilitata sul controller.

Problema 6: L'access point ha un codice mesh.

Questo messaggio è piuttosto generico e non indicativo della questione attuale. Per eseguire una diagnosi più approfondita fino a quando non viene aggiunta una registrazione aggiuntiva per questo problema specifico, esaminare il registro della console AP.

Problema 7: L'AP3700 è collegato a uno switch Catalyst serie 3850 con 3.3.0SE.

#show log

Problema 9: l'elenco di autorizzazioni AP è abilitato sul WLC; l'access point non è nell'elenco delle autorizzazioni.

Suggerimenti tecnici generali

In questa sezione vengono forniti alcuni suggerimenti utili.

• Quando si avvia il processo di risoluzione dei problemi, cancellare le tracce raccolte in precedenza per la funzione specifica. In questo caso, capwap, group-ap e tutte le tracce filtrate.
  
  • # Impostazione del capwap per il controllo della traccia
  • # Impostazione del gruppo di controllo traccia-ap
    
  • # Imposta controllo traccia sys-filtered-trace >> cancella le tracce filtrate e non può essere eseguito per singola funzionalità
  
  
  
• Il join AP sui controller degli accessi convergenti utilizza l'indirizzo MAC radio dell'access point. Quindi, quando si imposta un filtro per la traccia, usare l'indirizzo MAC di base o radio dell'access point. Immettere il comando show ap join status summary per trovare l'indirizzo MAC della radio.
  
  
• I problemi relativi ai certificati vengono gestiti da IOSd e richiedono l'utilizzo di debug, non di tracce, per un'ulteriore diagnosi.
