Resetting the Broadcom IP switch to factory defaults

Before installing a new switch software version and RCFs, you must erase the Broadcom switch settings and perform basic configuration.

1. Change to the elevated command prompt (#): enable

   Example

   (Routing)> enable
   (Routing) #
   

2. Erase the startup configuration: erase startup-config

   Example

   (Routing) #erase startup-config
   Are you sure you want to clear the configuration? (y/n) y
   
   
   (Routing) #
   

   This command does not erase the banner.

3. Reboot the switch: reload

   Example

   (IP_switch_A_1) #reload
   
   Are you sure you would like to reset the system? (y/n) y
   

   Note

   If the system asks whether to save the unsaved or changed configuration before reloading the switch, select No.
4. Wait for the switch to reload, and then log in to the switch.

   The default user is admin, and no password is set. A prompt similar to the following is displayed:

   Example

   (Routing)> 
   

5. Change to the elevated command prompt: enable

   Example

   Routing)> enable
   (Routing) #
   

6. Set the serviceport protocol to none: serviceport protocol none

   Example

   (Routing) #serviceport protocol none
   Changing protocol mode will reset ip configuration.
   Are you sure you want to continue? (y/n) y
   
   (Routing) #
   

7. Assign the IP address to the service port: serviceport ip ip-address netmask gateway

   Example

   The following example shows a service port assigned IP address 10.10.10.10 with subnet 255.255.255.0 and gateway 10.10.10.1:

   (Routing) #serviceport ip 10.10.10.10 255.255.255.0 10.10.10.1
   

8. Verify that the service port is correctly configured: show serviceport

   Example

   The following example shows that the port is up and the correct addresses have been assigned:

   (Routing) #show serviceport
   
   Interface Status............................... Up
   IP Address..................................... 10.10.10.10
   Subnet Mask.................................... 255.255.255.0
   Default Gateway................................ 10.10.10.1
   IPv6 Administrative Mode....................... Enabled
   IPv6 Prefix is ................................ fe80::dac4:97ff:fe56:87d7/64
   IPv6 Default Router............................ fe80::222:bdff:fef8:19ff
   Configured IPv4 Protocol....................... None
   Configured IPv6 Protocol....................... None
   IPv6 AutoConfig Mode........................... Disabled
   Burned In MAC Address.......................... D8:C4:97:56:87:D7
   
   (Routing) #
   

9. If desired, configure the SSH server.
   Note

   The RCF file disables the Telnet protocol. If you do not configure the SSH server, you can only access the bridge using the serial port connection.
   1. Generate RSA keys.

      (Routing) #configure
      (Routing) (Config)#crypto key generate rsa
      
      
   2. Generate DSA keys.

      (Routing) #configure
      (Routing) (Config)#crypto key generate dsa
      
      
   3. Enable the SSH server.
      If necessary, exit the configuration context.

      (Routing) (Config)#end
      (Routing) #ip ssh server enable
      

      Note

      If keys already exist, then you might be asked to overwrite them.
10. If desired, configure the domain and name server: configure

    Example

    The following example shows the ip domain and ip name server commands:

    (Routing) # configure
    (Routing) (Config)#ip domain name labs.Lenovo.com
    (Routing) (Config)#ip name server 10.99.99.1 10.99.99.2
    (Routing) (Config)#exit
    (Routing) (Config)#
    

11. If desired, configure the time zone and time synchronization (SNTP).

    Example

    The following example shows the sntp commands, specifying the IP address of the SNTP server and the relative timezone.

    (Routing) # 
    (Routing) (Config)#sntp client mode unicast
    (Routing) (Config)#sntp server 10.99.99.5
    (Routing) (Config)#clock timezone -7
    (Routing) (Config)#exit
    (Routing) (Config)#
    

12. Configure the switch name: hostname IP_switch_A_1

    Example

    The switch prompt will display the new name:

    (Routing) # hostname IP_switch_A_1
    
    (IP_switch_A_1) #
    

13. Save the configuration: write memory

    Example

    You receive prompts and output similar to the following example:

    (IP_switch_A_1) #write memory
    
    This operation may take a few minutes.
    Management interfaces will not be available during this time.
    
    Are you sure you want to save? (y/n) y
    
    Config file 'startup-config' created successfully .
    
    
    Configuration Saved!
    
    (IP_switch_A_1) #
    

14. Repeat the previous steps on the other three switches in the MetroCluster IP configuration.
