[joshep1]

I'm running Cisco 7200 lastest image (153-3.XB12) on GNS3 added Gigabit interfaces but when I try to acces a range the command is invalid R1(config)#interface range GigabitEthernet 1/0 - 2 the doc said it should be done this way and I have tried quite a lot of combination trying to get to work and still invalid can anyone enlight me on the matter?

Just double-check the interfaces IDs

The space before the dash is required. For example, the command interface range gigabitethernet 1 - 5 is valid; the command interface range gigabitethernet 1-5 is not valid.

interface range fastethernet 5/1 - 5, gigabitethernet 1/1 - 2
