I am in the process of gathering the system serial numbers all of our switches as well as the serial numbers of all of the GBICs in those switches.
CiscoWorks is able to provide the serial numbers of only the Master Switch in each switch stack and not the serial numbers of the member switches.
The only other obvious alternative is to log in to each switch stack and do a "show inventory" to obtain the serial numbers of the member switches in each switch stack.
I, then, figured out that an easier way to do it would be to use an SNMP tool to "get" the serial numbers of all switches in a switch stack without having to log in to each and every switch stack.
The SNMP tool I used to do this is IPSwitch's WS_Ping ProPack. Through specifying the IP address, the SNMP community string, and the Object Identifier for system serial numbers (188.8.131.52.184.108.40.206.220.127.116.11; entPhysicalSerialNum), I was able to "get" the system serial numbers of all switches in a switch stack without having to log in to each and every switch stack.
I also noticed that when I did a "get-bulk" request, I noticed a pattern. The following is an example:
18.104.22.168.22.214.171.124.126.96.36.199.1001=CAT0828N3ZQ --> system serial of first switch
188.8.131.52.184.108.40.206.220.127.116.11.2001=CAT0828N21Y --> system serial of second switch
18.104.22.168.22.214.171.124.126.96.36.199.3001=CAT0931N336 --> system serial of third switch
Using IPSwitch's WS_Ping ProPack was much better than logging into every switch stack and then doing the "sh inventory" command. Even though I did not have to log into the each and every switch stack, WS_Ping ProPack still appears to be limited in that it only allowed me specify only one IP address at a time to "get" the system serial numbers of switch stacks. I am wondering if there exists a tool that would allow me to specify a range of network address and "get" the system serial numbers of all switches in all switch stacks that fall in my specified IP address range.
Any input or insight would be great appreciated!
