You can do a "show flash" to see what you do have in FLASH and how much memory is available.įor DRAM and FLASH that works with Cisco routers - check I was at a Cisco convention several years ago and all the CCIE's kept talking about getting stuff for their labs at Anthony Panda Like Burt said, if you have enough FLASH and the IOS image is small, you could have 2 or more IOS's in FLASH and then tell the router which to boot to such as in a dual boot computer System image file is "flash:"Ĭisco 2611 (MPC860) processor (revision 0x203) with 45056K/4096K bytes of memory.ģ2K bytes of non-volatile configuration memory.Ĩ192K bytes of processor board System flash (Read/Write)
ROM: System Bootstrap, Version 11.3(2)XA4, RELEASE SOFTWARE (fc1) Here is a "show version for a 2600, first bold is the DRAM second bold is the FLASH -Ĭisco Internetwork Operating System Software
The IOS is going into FLASH and is loaded into RAM when the router boots.ĭo a "show version" and it will tell you the amount of DRAM and FLASH. If you are working on a lab router and working towards a Cisco cert - you should visit us over at the Cisco Cert forum here at Tek-TipsĪ little more on your router, if it is a Cisco 26xx router like a 2611 or 2610 then MAX DRAM is 64 and MAX FLASH is 16.
