How to Know that this Products are installed in 6509-E core switch with supervisor engine WS-SUP720-3B

BF-S720-64MB-RP Bootflash for SUP720-64MB-RP

MEM-S2-512MB Catalyst 6500 512MB DRAM on the Supervisor (SUP2 or SUP720)

MEM-MSFC2-512MB Catalyst 6500 512MB DRAM on the MSFC2 or SUP720 MSFC3

MEM-XCEF720-256M Catalyst 6500 256MB DDR, xCEF720 (67xx interface, DFC3A)

I have this problem too.

Hi Mohammed,

If I understand your question correctly (please clarify if I don't), you're asking what you can do to see how much bootflash you have in your sup, and see how much DRAM you have installed on various systems within your switch.

The bootflash is quite simple: Use the "dir bootflash:" command. Since the Native IOS CLI (assuming you're running NativeIOS) serves up the CLI from the RP (Route Processor), the result of this command will show you the bootflash available on the RP. Example:

SH3-100#dir bootflash:

Directory of bootflash:/

6 -rw- 22934 Dec 28 2005 15:25:55 -05:00 SH3-100.cfg

65536000 bytes total (63283340 bytes free)


You can see ~64MB total.

Finding the amount of DRAM installed on the Sup is easy too. You can just use the "show version" command to get this info. Now, you'll have to use different variations of the command for the various subsystems (RP, SP, DFC), but they all report it similarly. Looking at the RP in this NativeIOS switch (I'll restrict the output with the pipe):

SH3-100#sho ver | include memory

cisco WS-C6509 (R7000) processor (revision 3.0) with 458720K/65536K bytes of memory.

1917K bytes of non-volatile configuration memory.

8192K bytes of packet buffer memory.

There are two values there, 458M and 65M. Add them up and you get approx 512MB, which is the amount of DRAM avail on the RP.

To get the SP (Switch Proc) DRAM total, you have to issue the "sh ver" command from the SP itself. This can be done in two ways. First, you can drop down to the SP ("remote login switch") and issue the command directly. Second, you can use the "remote command switch show version" command from the RP (default) CLI. This is what I do here:

H3-100#rem comm sw sh ver | i memory

cisco Catalyst 6000 (R7000) processor with 458720K/65536K bytes of memory.

1917K bytes of non-volatile configuration memory.

8192K bytes of packet buffer memory.

Again, add the two values up and you get ~512MB memory installed on the SP.

The DFC3A is just another subsystem and you use the same command to get the memory on it. This particular switch happens to have a DFC3A installed on top of a WS-X6816-GBIC card in slot 4 (the same will work for DFCs on 67xx cards as well). So I tailor the command to show the info for slot 4:

SH3-100#rem command module 4 show ver | i memory

cisco Catalyst 6000 (SB1121) processor with 524288K bytes of memory.

379K bytes of non-volatile configuration memory.

Again, ~512MB memory here too.

If you have CatOS devices, the "sh ver" command works as well. On the Sup itself (SP, not MSFC), at the very bottom of the output, you'll see:


Module Total Used Free Total Used Free Total Used Free

------ ------- ------- ------- ------- ------- ------- ----- ----- -----

1 131072K 84951K 46121K 31232K 20444K 10788K 512K 391K 121K

Uptime is 128 days, 7 hours, 28 minutes

SH3-Dista-1> (enable)

This particular switch shows ~128MB total.

The MSFC runs IOS, so if you jump on the MSFC and issue the "show ver" command, you can use the same method as the first three to get an idea of the DRAM installed (I don't have one handy to show).

Hope this helps. If I answered the wrong question, let me know.
