I have developed some software modules that interact with various Cisco devices using SNMP and other mechanisms. My company has a small set of 8xx,17xx and 26xx routers with which I have been testing this software. In the near future I would like to perform tests using different (higher end) routers and switches as well as other IOS versions. For this reason I'm looking into companies that provide testing labs / facilities with Cisco devices. I haven't been able to come up with much. Does anyone know of any test labs in Europe or the US where I can do a few days of experimenting and testing (hooking up my software, configuring devices, generating network traffic)? Remote access is also a possibility of course.
