Dear All,
I bought routers from some one with the condition that he will give me
the 12.2T IOS with the routers, now I am not sure that if the IOS that
these routers have is 12.2T or it is some different version. Please
calarify what will be the brief name for the IOS I am mention here..
 
c2500-jk8os-L.122-1d.bin
 
c4500-js-mz.122-7b.bin
 
I1214.OOO (Image in 2522)
 
c2500-js-L.122-26.bin (Image in 2511)
 
c3620-i-mz.122-3.bin
 
c2600-i-mz.123-9.bin
 
Another problem is that 2500 series routers have FLASH as Read Only,
were those routers had built like this or there is option to have FLASH
with Read/Write option? And how one can upgrade the IOS in that type of
router when its READ ONLY and you can not erase FLASH?
 
One router has 16MB Flash, and in show version output it shows that 8MB
is read only and 8MB is Read/Write? Again how I can upgrade the IOS if I
would need some time in future? and is it the option that you can buy
FLASH Read only OR Read/Write and how expensive is Read/Write than Read
Only?
 
Thanks in advance for your time......
 
Regards,
