Questo documento descrive come recuperare una password su uno switch Catalyst serie 6500 con un Supervisor 720 con software di sistema Cisco IOS® con una versione precedente alla 12.2(17)SX.
La differenza nella procedura tra le versioni del software Cisco IOS precedenti alla 12.2(17)SX è causata dall'ID bug Cisco CSCec36997 (solo utenti registrati) (il recupero della password su sup720-native causa un arresto anomalo del processore (SP). Quando lo switch è soggetto a questo bug, dopo circa 10 secondi dall'interruzione in RP ROMMON, è possibile modificare il registro di configurazione in 0x2142. Dopo questi 10 secondi, lo switch viene ricaricato con il caricamento forzato del software. Tuttavia, se si modifica il registro di configurazione con questo valore prima dell'arresto anomalo, la modifica avrà effetto dopo il ricaricamento e sarà possibile continuare con il resto della procedura.
Nessun requisito specifico previsto per questo documento.
Questo documento è relativo ai sistemi Supervisor 720 con software Cisco IOS versioni precedenti alla 12.2(17)SX. Se il supervisor 720 esegue il software Cisco IOS versione 12.2(17)SX o successive, fare riferimento alla procedura di recupero della password per gli switch Catalyst serie 6000/6500 con software Cisco IOS.
La sequenza di avvio è diversa sul Catalyst 6500/6000 con Cisco IOS rispetto al Cisco serie 7200 Router perché l'hardware è diverso. Dopo aver spento e riacceso la scatola, l'SP si avvia. Dopo circa 25-60 secondi, trasferisce la proprietà della console al processore di routing (MSFC). L'RP continua a caricare l'immagine software in dotazione. È fondamentale premere Ctrl-Break subito dopo che l'SP ha ceduto il controllo della console all'RP. Se si invia la sequenza di interruzione troppo presto, si finisce nel ROMMON dell'SP, che non è il punto corretto. Inviare la sequenza di interruzione dopo aver visualizzato questo messaggio sulla console:
00:00:03: %OIR-6-CONSOLE: Changing console ownership to route processor
Dopo questo punto, il recupero della password sarà lo stesso di un router normale.
Nota: da questo momento in poi, lo switch Catalyst serie 6500 con software Cisco IOS viene chiamato router.
Per ulteriori informazioni sulle convenzioni usate, consultare il documento Cisco sulle convenzioni nei suggerimenti tecnici.
Lo switch è configurato come un router perché sullo switch è in esecuzione il sistema operativo Cisco IOS. La procedura di recupero della password segue gli stessi passaggi di un router Cisco serie 7200. L'unica eccezione è che è necessario attendere circa 25-60 secondi prima di avviare la sequenza di interruzione.
Collegare un terminale o un computer con emulazione terminale alla porta della console del router. Impostare il terminale come segue:
9600 baud rate No parity 8 data bits 1 stop bit No flow control
Le specifiche richieste per i cavi console sono descritte nel documento Specifiche dei cavi. Per istruzioni su come connettersi alla porta della console, consultare la Guida all'installazione del modulo. La sezione Collegamento alla porta della console - Solo Supervisor Engine fornisce informazioni utili.
Se si ha ancora accesso al router, usare il comando show version e registrare l'impostazione del registro di configurazione. In genere è 0x2102 o 0x102. Fare clic qui per visualizzare l'output di esempio di un comando show version.
Se non si ha accesso al router (a causa di una password di accesso o TACACS persa), si può presumere che il registro di configurazione sia impostato su 0x2102.
Spegnere e accendere il router con l'aiuto dell'interruttore di alimentazione.
Premere Break sulla tastiera del terminale subito dopo che l'RP ha acquisito il controllo della porta della console. Sul Catalyst 6500 con Cisco IOS, l'SP viene avviato per primo. Quindi passa il controllo all'RP. Dopo che l'RP ha acquisito il controllo, iniziate la sequenza di interruzione. L'RP ha acquisito il controllo della porta della console quando viene visualizzato questo messaggio. (Non avviare la sequenza di interruzione finché non viene visualizzato questo messaggio):
00:00:03: %OIR-6-CONSOLE: Changing console ownership to route processor
A causa dell'ID bug Cisco CSCec36997 (solo utenti registrati) (il recupero della password su sup720-native causa un arresto anomalo dell'SP), sono disponibili circa 10 secondi per completare il passaggio 6 prima che lo switch si arresti.
Se la sequenza di interruzione non funziona, vedere Combinazioni di sequenze di tasti di interruzione standard durante il recupero della password per altre combinazioni di tasti.
Digitare confreg 0x2142 al prompt rommon 1> per avviare il sistema da Flash senza caricare la configurazione.
Lo switch si blocca in seguito a un arresto anomalo del software:
rommon 1 > 00:00:41: %SYS-SP-3-LOGGER_FLUSHED: System was paused for 00:00:00 to ensure co. 00:00:41: %SYS-SP-2-INTSCHED: 't_idle' at level 7 -Process= "SCP Download Process", ipl= 7, pid= 57 -Traceback= 4013991C 401232B4 402827F4 40282994 40283010 405CB010 402A9858 4013C 00:00:41: %SYS-SP-2-INTSCHED: 't_idle' at level 7 -Process= "SCP Download Process", ipl= 7, pid= 57 -Traceback= 4013991C 401232B4 402827F4 40282994 40283010 405CB010 402A9858 4013C 00:00:41: %SYS-SP-2-INTSCHED: 't_idle' at level 7 -Process= "SCP Download Process", ipl= 7, pid= 57 -Traceback= 4013991C 401232B4 402827F4 40282994 40283010 405CB010 402A9858 4013C 00:00:41: %OIR-SP-6-CONSOLE: Changing console ownership to switch processor *** System received a Software forced crash *** signal= 0x17, code= 0x24, context= 0x4269f6f4 PC = 0x401370d8, Cause = 0x3020, Status Reg = 0x34008002
Il router si riavvia. Tuttavia, la configurazione salvata viene ignorata a causa del fatto che il registro di configurazione è impostato su 0x2142. Se si rileva che la configurazione del router è ancora presente (nome host ancora precedente), significa che il registro di configurazione non è stato modificato in 0x2142 nel tempo precedente all'arresto anomalo. In questo caso, ricominciare da capo (Passaggio 4). Se il registro di configurazione è stato modificato correttamente in 0x2142, verranno visualizzate le domande sulla configurazione iniziale dopo il ricaricamento.
Digitare no dopo ciascuna domanda di configurazione o premere Ctrl-C per saltare la procedura di configurazione iniziale.
Digitare enable sul prompt Router>. È attiva la modalità di abilitazione. Viene visualizzato il prompt Router#.
È importante usare i comandi configure memory o copy start running per copiare la NVRAM (Nonvolatile RAM) nella memoria. Non usare il comando configure terminal.
Eseguire il comando write terminal o show running. Questi comandi mostrano la configurazione del router. In questa configurazione, il comando shutdown è presente in tutte le interfacce. Ciò significa che tutte le interfacce sono attualmente chiuse. Le password vengono visualizzate in formato crittografato o non crittografato.
Eseguire il comando configure terminal per accedere alla modalità di configurazione globale e apportare le modifiche. Il prompt è ora nomehost(config)#.
Utilizzare il comando enable secret < password > in modalità di configurazione globale per modificare la password di abilitazione.
Eseguire il comando config-register 0x2102 o il valore registrato nel passaggio 2 in modalità di configurazione globale (Router(config)#) per ripristinare il valore originale della configurazione.
Modificare le eventuali password dei terminali virtuali:
Router(config)#line vty 0 4 Router(config-line)#password cisco Router(config-line)#^Z Router#
Eseguire il comando no shutdown su ciascuna interfaccia normalmente in uso. Eseguire un comando show ip interface brief per visualizzare un elenco delle interfacce e il loro stato corrente. È necessario essere in modalità abilitazione (Router#) per eseguire il comando show ip interface brief. Di seguito è riportato l'esempio di un'interfaccia:
Router#show ip interface brief Interface IP-Address OK? Method Status Prol Vlan1 172.17.10.10 YES TFTP administratively down dow Vlan10 10.1.1.1 YES TFTP administratively down dow GigabitEthernet1/1 unassigned YES unset administratively down dow GigabitEthernet1/2 unassigned YES TFTP administratively down dow GigabitEthernet2/1 unassigned YES TFTP administratively down dow GigabitEthernet2/2 unassigned YES TFTP administratively down dow FastEthernet3/1 172.16.84.110 YES TFTP administratively down dow <snip>... Router#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#interface fastEthernet 3/1 Router(config-if)#no shutdown Router(config-if)#exit Router(config)# <do other interfaces as necessary...>
Premere Ctrl-Z per uscire dalla modalità di configurazione. Il prompt è ora nomehost#.
Eseguire i comandi write memory o copy running startup per eseguire il commit delle modifiche.
Nell'esempio viene mostrata una procedura di recupero della password effettiva. Questo esempio viene creato con l'aiuto di uno switch Catalyst serie 6500. Iniziare con i comandi show version e show module per visualizzare i componenti utilizzati in questo esempio.
