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 display:

Group The multicast group ID of the broadcast group (always 256)

Member Ports A map of all ports in broadcast tree

Member ISL Ports A map of all E_Ports in broadcast tree

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.

The output from this command varies, depending on switch type.

Examples To display the broadcast routing information for all ports in the switch:

In this example, from a switch with 128 ports, 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.
