Hi Bhavesh,
The "set community members" is used inside a policy statement. Most likely to match on a specific community configured that has been under the label "bandwidth". In the IOS world, a route-map is more or less equivalent to a policy statement. We would need the entire policy statement in order to tell you what the equivalent route-map would look like.
