max. number of loopback interfaces on a 3560-8PC-S or a 2960TC-8-L
our application monitoring engineer needs to be able to ping thousands of IP addresses and we decided to offer the following solution to him: a Cisco 8 port Office Switch such as a 3560-8PC-S or a 2960TC-8-L.
The Problem we're now facing is that only up to 64 loopback Interfaces (0 - 63) could be created. It's not possible to create a loopback Interface with the num value 64 or higher. Any ideas what we could do to resolve this issue ?
We're running IOS 12.2(55)EX2. Peculiarly, 0-2147483647 is offered when you enter Interface loopback ? but fact is we can't generate a loopback Interface 64 or higher.
Switch(config)#int lo ? <0-2147483647> Loopback interface number
I'm not sure if I really understand your needs, but with the help of secondary addresses, an interface can have more than one ip-address configured. But I never tested if that really scales to "thousands" ...

sorry my previous statement was not 100% correct. While I was able to create a loopback interface with the num value 64 I was again not able to create more than 64 loopbacks in the sum with IOS 15. So the question is still open.
thanks. I think I will go for the alternative solution and try it with IP secondaries on just one loopback interface. I was able to create 2000 IP secondaries under one loopback interface (probably even more would have been possible but 2000 are sufficient for the moment). Thanks so much for your appreciated help.
