Description
Use this command to display the broadcast routing information for all ports in the switch. The broadcast
routing information indicates all ports that are members of the broadcast distribution tree: ports that are
able to send and receive broadcast frames.
Normally, all F_Ports and FL_Ports are members of the broadcast distribution tree. The broadcast path
selection protocol selects the E_Ports that are part of the broadcast distribution tree. The E_Ports are chosen
in such a way to prevent broadcast routing loops.
The following fields display:
The broadcast routing information for the ports is displayed as a set of hexadecimal bit maps. Each bit in
a bit map represents a port, with the least significant bit in each row representing port 0, 32, 64, and so
on. For more information on reading hexadecimal bit maps, refer to the HP StorageWorks Fabric OS 4.x
procedures user guide.
NOTE: The output from this command varies, depending on switch type.
When this command runs on a 128-port switch, the member ports consist of ports 7, 13, 42, 84, 85, and
86. The final member ports bit set represents the embedded port (frames sent to be handled by firmware)
and is typically set.
