bcastShow
Displays broadcast routing information.
Synopsis bcastshow
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 are displayed:
Group
Member Ports
Member ISL Ports
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.
Note The output from this command may vary, depending on the hardware platform.
The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may
be in place. Refer to chapter 1, "Using Fabric OS commands" and Appendix A, "Command
Availability" for details.
