: NodeTopologyBridge fails on Cisco Switch ME36/ME34/ME35

Added more control and a fix for cisco devices

The Cisco Switch is ME34XX.
When Walking the BRUDGE-MIB only shut interface are in port table.
But in the BFT I got the right BridgePort....so it seems that there is no mapping from bridgeport to valid ifindex,.
