[c-nsp] need help about switch cisco 4 9 4 8

[chloe K]

Hi Rich
   
  Thank you so much for your fast response.
   
  for the 1st quesiton, what is "config-register = 0x1"?
   
  for the 2nd question, I have same model switch
   
  there is int "FastEthernet1" to let me to configure the management int

  interface FastEthernet1
 no ip address 
 speed auto
 duplex auto
   
  But in this switch, I can't see this int in show running config so that I can't configure it for the management port
   
  Do you have any idea?
   
  Thank you

  Chloe,

The config-register of 0x2142 is usually configured when someone does password recovery on the device.  You need to change it back to 0x2102 then reset the switch:

confreg 0x2102
reset

This should cause switch to boot up with config register of 0x2102 which tells it to load the configuration from NVRAM (normal default operation).   Once the Cisco IOS is booted and you can get in to do configuration on the switch you will want to setup a management IP address.    Traditionally switches have a "Vlan1" interface which is the interface you should put your management IP on.

example shown assumes the following:
x.x.x.x = management IP
y.y.y.y = management IP subnet mask
z.z.z.z = default gateway (.1 or whatever you are using for the subnet).


config term
!
!
  interface vlan 1
  ip address x.x.x.x y.y.y.y
!
ip default-gateway z.z.z.z
!
!
end
wr mem


Hope this helps!

  Hi

 I have problems in this switch 49 48

 1/ I can't setup the management interface.
 I have another same modeul. I can see there is Fasthernet to set it up as management port.

 2/ After reload, I lost configuration. I did copy run start
 It said that it can't find the Valid boot environment

  config-register = 0x2142
 Autobooting using BOOT variable specified file.....
  Could not find a valid file in BOOT environment variable.
