I have bought a new 2960 switch. The IOS image does not support ISL encapsulation. As I would like to test some STP features, which IOS image does support ISL encapsulation? And how can I get it? Thanks.
I have a feeling that the Cisco 2960 series of switches only supports 802.1Q truking, not Ciscos ISL so this can't be fixed by an IOS upgrade.
Is there a reason you muct use ISL instead of 802.1Q trunking?
Hello Jonathan and thanks for your answer.
I would like to test the difference between "pure" PVST and PVST+.
As I will buy a 3560 switch too, do you know if this series supports it?
