Cisco::Serial Numbers


To determine the serial number for the chassis and other components, issue the show idprom command, as this example shows:

6509# show idprom ?
all selects all FRU-types
backplane specify backplane
clock specify clock
earl specify earl
fan-tray specify fan-tray
interface interface name
module specify module
power-supply specify power-supply
rp specify RP (MSFC)
supervisor specify supervisor
vtt specify VTT To obtain the chassis serial number, issue the show idprom backplane command, as this example shows:

6509# show idprom backplane
IDPROM for backplane #0
(FRU is 'Catalyst 6500 6-slot backplane')
OEM String = 'Cisco Systems'
Product Number = 'WS-C6506'
Serial Number = 'TBA03270652'
Manufacturing Assembly Number = '73-3436-01'
Manufacturing Assembly Revision = 'A0'
Hardware Revision = 1.0
Current supplied (+) or consumed (-) = -ATo obtain the module serial number, issue the show idprom module slot # command. Alternatively, you can issue the show module command, as this example shows:

6509# show module

Microsoft::Excel::Formula::Sort by IP Number

I hate that editors, excel, SQL reports, etc will not sort properly by IP address.
This great Excel formula will calculate a unique integer value for an IP address to allow sorting on that value:

=((VALUE(LEFT(A2, FIND(".", A2)-1)))*256^3)+((VALUE(MID(A2, FIND(".", A2)+1, FIND(".", A2, FIND(".", A2)+1)-FIND(".", A2)-1)))*256^2)+((VALUE(MID(A2, FIND(".", A2, FIND(".", A2)+1)+1, FIND(".", A2, FIND(".", A2, FIND(".", A2)+1)+1)-FIND(".", A2, FIND(".", A2)+1)-1)))*256)+(VALUE(RIGHT(A2, LEN(A2)-FIND(".", A2, FIND(".", A2, FIND(".", A2)+1)+1))))

And to turn that number back into an IP number:

=IF(B2<>"", CONCATENATE(INT(B2/256^3), ".", INT(MOD(B2, (256^3))/(256^2)), ".", INT(MOD(MOD(B2, 256^3), 256^2)/256), ".", MOD(MOD(MOD(B2, 256^3), 256^2), 256)), "")

VMware::P2V::Uninstall hidden "stale" devices

From: VMWare Community

After a physical conversation a number of “stale devices” will exist in the new virtual machine. These are hardware devices which are no longer required.
Windows 2000 & 2003
To identify which devices are no longer physically installed on your virtual machine, use the Microsoft environment variable devmgr_show_nonpresent_devices. This is explained in the Microsoft article:

MS KB315539

1. From the command prompt, type:
set devmgr_show_nonpresent_devices = 1
2. Start the search. Type:
start devmgmt.msc
3. From the Device Manager, list the devices.
Select: View > Show hidden devices.
4. Deinstall the listed devices:
Select the device and uninstall it from the Device Manager.


WAN::Latency::BES::Blackberry Enterprise Server

Interesting rule of thumb from Blackberry support:
The link between the BES server and the Exchange mailbox database server should, be on average, no more than 35ms.
