Bus Mapping on OmniSwitch 7700/7800/8800
Switches
Xybus Mapping
Each board type has own mapping, described for all existing board type below.
• OS7-ENI-C24 and OS8-ENI-C24: Single slice board, connects two Catalina MAC ASICs through
xybus0 and xybus1.
• OS7-ENI-FM12: Single slice board, connects one Catalina MAC ASICs through xybus0,
• OS7-GNI-U2: Single slice board, connects two Catalina MAC ASICs through xybus0 and xybus1.
• OS8-GNI-U/C8: Four slice board, each slice connects two Catalina MAC ASICs through xybus0 and
xybus1.
• OS7-GNI-U/C12: Single slice board, connects two Firenze MAC ASICs through xybus0 and xybus1.
• OS8-GNI-C24: Two slices board, each slice connecting two Firenze MAC through xybus0 and
xybus1.
• OS8-GNI-U24: Four slice board, Slice 0 and 2 connecting one Firenze MAC through xybus0 and Slice
1 and 3 connecting one Firenze MAC through xybus1.
Fbus Mapping
Note. Dshell commands should only be used by Alcatel personnel or under the direction of Alcatel.
Misuse or failure to follow procedures that use Dshell commands in this guide correctly can cause lengthy
network down time and/or permanent damage to hardware.
Falcon (OmniSwitch 7700/7800) Fbus Mapping
-> dshell
Working: [Kernel]->nanListMapping
Full Chassis (OS7800):
Fbus/Nan Port: 0,2,4,6,7,5,3,1,14,12,10, 8, 9,11,13,15
NI Slot: 1,2,3,4,5,6,7,8, 9,10,11,12,13,14,15,16
Half Chassis (OS7700):
Fbus/Nan Port: 0,2,4,6,1,3,5,7
NI Slot: 1,2,3,4,5,6,7,8
Eagle (OmniSwitch 8800) Fbus Mapping
Unlike Falcon, Eagle (OmniSwitch 8800) uses strict fbus number starting from 0 through 63.
Formula: Fbus_number = (slot_number - 1) * 4
For example, a OS8-GNI-U8 in slot 4, (4-1)*4=12. Since the OS8-GNI-U8 is a 4-slice board, Fbus
number starts from 12, up to 15.
