HUAWEI ROUTER LTE

In questa pratica guida, vedremo come configurare da zero un router Huawei AR500 Series creando una LAN interna un TRUNK VLAN verso un altro Router.

Componenti utilizzati:

  1. Un Router Huawei AR502
  2. Cavo CONSOLE se sei sprovvisto puoi acquistarlo da qui.
  3. Una SIM 4G LTE di qualsiasi operatore (es. VERY MOBILE )
  4. Un PC con porta Ethernet

Livello difficoltà: Medio

fig.1 – Diagramma di rete

Osservando diagramma qui sopra, andiamo a configurare il Router Huawei AR500 series che chiameremo R1, in maniera tale da avere una LAN direttamente su esso nattata verso l’ip pubblico della SIM e una seconda porta configurata come TRUNK VLAN in modo da portare la connessione LTE ad un router secondario che chiameremo R2 e allo stesso tempo assegnarle un’ip della LAN di R2 in modo da avere un’accesso diretto dalla stessa per comodità e management del dispositivo.

Questa guida potrebbe funzionare su altri modelli di Router Huawei, non mi assumo nessuna responsabilità nell’eventualità alcuni comandi siano completamente diversi o non funzionanti.

Obbiettivo 1: Stabilire la conessione e l’accesso da terminale con il Router.

  1. Colleghiamoci al Router tramite il cavo console.
  2. Apriamo il software Putty e seleziona la modalità “Serial“
  3. Digita la porta seriale corretta nel campo “Serial Line“
  4. Clicca sul tasto “OPEN“
  5. Dovresti ora stabilire la connessione da terminale il Router Huawei LTE.

fig.2 – Putty modalita serial

Se hai un pc con sistema operativo MacOS, dai uno sguardo a questa guida: Cisco da terminale MacOS

Potrai accedere direttamente al dispositivo senza ulteriori software aggiuntivi.

Obbiettivo 2: Accendere e resettare il Router

Una volta acceso il router, ci vorranno circa 10 minuti perchè esso completi il ciclo di avvio.

Una volta completato il router richiederà un username.

Le credenziali di default dei Router Huawei sono:

  • user = admin
  • password = Admin@huawei

Se non riuscussi ad accedere con queste credenziali potrebbe essere necessario resettare il router.

Ti spiego come resettarlo nel prossimo Obbiettivo.

Obbiettivo 3: Reset del Router

Huawei, permette due modalità di reset su questo Router LTE.

– Modalità 1: Reset con tasto fisico.

Aprire lo sportellino situato nella parte inferiore del router che contiene l’alloggiamento della SIM ed il pulsante per il reset della configurazione. Con l’alimentazione scollegata provvedete ad inserire la SIM nell Slot e prima di richiudere lo sportellino procedete con il reset.

Tenere premuto il tasto CONFIG e date l’alimentazione al router, continuate a tenere premuto fino a che non lampeggia il led rosso ALM, a questo punto il router è resettato alle impostazioni iniziali, potete chiudere lo sportellino e procedere con la configurazione.

Se questo non avenisse, probabilmente il reset del router è bloccato di Default. Eventualmente dovrai indicare quanto indicato nella Modalità 2.

– Modalità 2: Reset da CLI (Command Line Interface)

Eseguire l’avvio con CLI aperta.

Ad un certo punto apparirà una voce che indica:

Initializing I2C Bus:OK
Press Ctrl+B to break auto startup … 2

Quando appare questa indicazione premere immediatamente Ctrl + B.

Verrà richiesta una password che in genere è quella di default (Admin@huawei).

Inserire le credenziali e dovrebbe apparirti una schermata simile a questa:

huawei ar500 series
fig.3 – Avvio BootLoader Menu
  • Digitiamo 7 per accedere al menu “Password Manager” + Invio;
  • Digitiamo 2 per selezionare la voce “Clear the console login password” + Invio;
  • Digitiamo 0 per selezionare la voce “Return” + Invio;
  • Digitiamo 6 per selezionare la voce “Reboot” + Invio.

Ora il router rieseguirà un nuovo boot e una volta ultimato troverai il router già loggato con la vecchia configuraione attiva.

In ogni passaggio, verrà ripetuta la configurazione immessa negli obbiettivi precedenti, in quanto diversamente è facile perdere il filo. Verrà evidenziata in verde la parte interessata dal medesimo obbiettivo.

Se vuoi leggere la configurazione attuale digita: display current-configuration

[Huawei]
[Huawei]display current-configuration

Dovresti visualizzare la configurazione attuale.

Se volessi conservarla copiala e incollala in un file testo, perchè ora andremo ad eseguire il vero e proprio reset.

Digita nel terminale: factory-configuration reset

[Huawei]
[Huawei]factory-configuration reset 

Warning: It will clean the configuration which you have saved. If you have set the factory-configuration by hand, it will start from the modified factory-configuration, else it will start from the original one, when you restart the device. Continue? [y/n]:

Digitare Y seguito da invio per resettare a default il Router Huawei LTE.

Ora riavvia il router digitando: reboot

[Huawei]
[Huawei]reboot

Verrà chiesta conferma sul comando di reboot per cui confermeremo digitando Y quando richiesto.

Una volta riavviato, eseguire l’accesso con credenziali di default.

Verrà richiesto di inserire obbligatoriamente una nuova password, una volta inserita siamo pronti a configurare il router. Verrà richiesto se disattivare l’auto configurazione, selezioniamo YES.

Obbiettivo 4: Rinominiamo il Router

Al mio router darò il nome di Huawei-AR502. Su terminale digito:

<Huawei>
<Huawei>system-view
[Huawei]
[Huawei]sysname Huawei-AR502
[Huawei-AR502]

Obbiettivo 5: Configuriamo l’interfaccia GigabitEthernet 0

Di default l’interfaccia GE0 è abinata alla VLAN 1 di default con IP 192.168.1.1 vediamo come modificarlo seguendo le indicazioni del diagramma.

Diamo una descizione all’interfaccia e configuriamo il DHCP server sull’interfaccia VLAN1 assegnando un pool 192.168.255.100-200 con un lease di 43200 secondi (12ore).

Obbiettivo 6: Configurariamo l’interfaccia GigabitEthernet 1

Quest’interfaccia avrà lo scopo principale di portare la rete LTE nattata ad un Router indicato R2 nel diagramma e attribuire un indirizo IP della LAN del Router 2 in maniera da facilitarne il management.

Per fare questo utilizzeremo le VLAN, configurando l’interfaccia come TRUNK della VLAN 10 (LAN2) e della VLAN 835 (LTE nattata /30).

Obbiettivo 7: Configurare la Default-Route

Per far in modo che ora il Router Huawei possa fa navigare le subnet 192.168.255.0/24 e 10.0.0.0/30 con l’interfaccia LTE, dovremo inserire la default route.

Ora il router dovrebbe navigare correttamente.

Obbiettivo 8: Configurare l’accesso al router da SSH

Configuriamo un’accesso SSH in modo da collegarsi al Router senza cavo seriale Console. Ma direttamente via IP.

Obbiettivo 9: Configuriamo l’orario e il NTP client.

Fondamentale per avere un riscontro anche a livello LOG, impostare correttamente l’orario sul nostro dispostivo HUAWEI.

Se vuoi visualizzare l’ora da CLI digita:

Obbiettivo 10: Impostiamo un banner.

Nei router dove la configurazione avviene esclusivamente o sopratutto da CLI, è fondamentale impostare un banner con eventuali informazioni di accesso. Nell’eventualità non fossero necessarie delle indicazione per l’accesso potrebbe venir utilizzata questa funzione anche a puro scopo pubblicitario.

Qui di seguito vediamo come configurarlo.

Nel mio caso ho inserito un banner come da immagine seguente:

La configurazione del router è stata ultimata come da diagramma.

Tieni presente che questa configurazione verrà presto integrata con un multilab dove la porta configurata come TRUNK VLANS andrà ad interfacciarsi con un Router Cisco.

Vuoi ulteriori infomazioni su questa configurazione, o vuoi fare qualche domanda per approfondire?
