Software command to see RAM DIMMs or SIMMs configuration in Cisco 3600 ?

I would need to understand if there's a software way to display the hardware memory configuration (how many and which simms, dimms are inside) of a Cisco 3600

Thanks in advance for any reply.

Generally no, however, you can use the hw configuration guide:

to get a good idea on what the configuration. Since the router can only have so many configurations you can find out what is inside by doing a

sh ver & sh mem & sh proc mem:

sh ver is good for a general idea. sh mem tells you what is being used and sh proc mem shows you the processes being used and the memory being used.

will give you the memory configuration and from that you can see via the configuration guide what your configuration is like.

cisco 3640 (R4700) processor (revision 0x00) with 91136K/7168K bytes of memory

Processor board ID 27581517

R4700 CPU at 100Mhz, Implementation 33, Rev 1.0

Bridging software.

X.25 software, Version 3.0.0.

SuperLAT software (copyright 1990 by Meridian Technology Corp).

TN3270 Emulation software.

1 Ethernet/IEEE 802.3 interface(s)

1 FastEthernet/IEEE 802.3 interface(s)

4 Serial network interface(s)

1 ATM network interface(s)

DRAM configuration is 64 bits wide with parity disabled.

125K bytes of non-volatile configuration memory.

32768K bytes of processor board System flash (Read/Write)

Configuration register is 0x2102

Hope this helps.

Re: Software command to see RAM DIMMs or SIMMs configuration in

I'm afraid about that; for example: a Cisco 3640 equipped with 64MB of DRAM could be equipped in two ways in terms of DIMMs:

1) Four DIMMs of 16MB each

2) Two DIMMs of 32MB each

Depending on this it's clear that if you need to field upgrade this platform to 96MB you don't know if two 16MB DIMMs are necessary (case 2), or if you need to replace in case 1 two DIMMs with two new 32MB one.

Apart from the different cost, this is the point. Do we need to open the boxes everytime ?
