Why do we have two flash memories flash: and flash1:  are they same thing or different ?

No they are not.

"flash:" means the flash directory of the MASTER switch.

"flash1:" means the flash directory of switch 1 of the stack.

"flash1:" does NOT necessarily mean it's the flash memory of the master switch.

But i have only one switch why does it show both flash: and flash1: information, with same size and same details.

many thanks,

But i have only one switch why does it show both flash: and flash1: information, with same size and same details.

Sure.  If you only have ONE switch then "flash:" and "flash1:" are the same.  But my response is based on multiple switches in a stack and switch 1 is NOT the stack master.

[kamrannaseem]

what if i have four switches in the stack how would it display the flash: information ?

would it be like ?

flash:

flash1:

flash2:

flash3:

many thanks.

Depends.

It'll depend on which switch is the master.

The master switch will have "flash:".  So if your master is switch #4, then the output to "dir flash:" and "dir flash4:" are the same.

To reiterate what Leo has already described, "flash" is the flash of whatever switch is running as the master switch.

"flash#", is the flash for switch#.

"flash" will be the same as SOME "flash#, again for the switch# that is the current master for the stack.  (If there's only one switch, it will be the master.)

Switch numbers do not need to start with 1 nor do then need to be consecutive.  For example, your example of a stack of 4 might be:

stack1 - flash1

stack2 - flash2

stack3 - flash3 (active master - so it's also "flash")

stack4 - flash4

or for example:

stack9 - flash9 (active master - so it's also "flash")

stack3 - flash3

stack7 - flash7

stack4 - flash4

Hi Leo,

I mistakenly deleted flash:

I am on switch: mode how do i come out of that and load the new IOS.

any help will be much appriciated.

many thanks.

Kamran,

f you are able to reboot the switch I would do the following:

reboot the switch

press on the mode button in order to come in rommon mode

switch: flash_init

switch: rename flash:config.text flash.config.text.temp

switch:boot

The switch will boot without any configuration because it can't find config.text.

Answer 'no' for initial configuration

switch>en

switch#copy flash:config.text.temp run

switch#wr

and then you've to look what's configured

aaa new-model

aaa authentication login default local

or

line con 0

login local

if this is true> check if there is a

user xxx secret/password xxxx is configured

I suspect that no user x secret xxx is configured.

Else you can help by posting all related console

HTH

hi Leo i am shrihan i need a clarification from u on this topic.

if bin file  is shown under flash & flash1: in same switch & if i  require to erase ios then from which flash should i remove?

whether i issue command delete flash:

                    or

                                      delete flash1:

if i use first option will it delete flash1: contain also ?

Hi Shiran,

'sh flash' shows the contents of the master switch, and 'sh flash1' shows the contents of switch1.

It is possible in a switchstack that the master switch is not switch 1 so 'sh flash' and 'sh flash1' will display different results.

Using 'sh switch' will show you which is the master switch and therefore which flash memory is displayed by 'sh flash':

sh switch
