Display broadcast routing information.
Synopsis
bcastShow
Availability All users
Description Use this command to display the broadcast routing information for all ports
in the switch (known to the FSPF path selection/routing task). The
broadcast routing information indicates all ports that are members of the
broadcast distribution tree (that is, 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 broadcast routing information displays as a set of bit maps. Each bit in
a bit map represents a port, with the least significant bit representing port 0.
If a bit is set to 1, that port is part of the broadcast distribution tree.
The following fields are displayed:
Operands None.
Group
Displays the multicast group ID of the broadcast
group.
Member Ports
Displays a map of all ports in broadcast tree.
Member ISL Ports
Displays a map of all E_Ports in broadcast tree.
Static ISL Ports
Reserved.
