60 Fabric OS commands
Displays broadcast routing information.
Synopsis
bcastshow
Availability
all users
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_Port members of this tree in a manner designed to prevent broadcast
routing loops.
The following fields appear:
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, see the HP StorageWorks Fabric OS 5.x
administrator guide.
NOTE: The output from this command varies, depending on switch type.
Operands
none
