I understand there is COS available on the 2950. However, it depends on the type of software that it is running. There is an EI and SI version available. How are one tell, by looking at the output for the sho ver if the 2950 will support the COS.
Here is the example of a sho ver from one of my 2950s. How can I tell if it supports COS?
