show fabric route multicast

show fabric route multicast
Displays ISLs that receives any forwarded Broadcast, unknown Unicast, and Multicast (BUM)
traffic.
Synopsis show fabric route multicast [rbridge-id | all]
Operands rbridge-id Specifies the RBridge ID. This is not valid in standalone mode.
all Specifies all switches in the fabric.
Defaults None
Command Modes Privileged EXEC mode
Description Use this command to display the multicast routing information for all ports in the switch.
The multicast routing information indicates all ports that are members of the multicast distribution
tree ports that are able to send and receive multicast frames. The command displays the following
fields:
Rbridge-id RBridge ID of the switch. Valid values range from 1 through 239.
Mcast Priority Mcast priority value of the switch. Valid values range from 1 through 255.
Enet IP Addr The switch Ethernet IP address.
WWN World Wide Name of the switch.
Name Switch name.
Src-Index Source index of the local RBridge.
Src-Port Source port of the local RBridge in the format “local-rbridge-id/slot/port”.
Nbr-Index Neighbor Index of the ISL connected from local port.
Nbr-Port Neighbor port of the ISL connected from the local RBridge in the format
“nbr-rbridge-id/slot/port”.
Usage Guidelines This command is not available in standalone mode. If this command is executed without
operands, it displays the multicast information of the local RBridge.
The show fabric family of commands display neighbor and local port information when connected
to a down-level RBridge.
When a fabric is running normal mode (switches are running Network OS 4.1.0 or later), CLI output
displays the QSFP breakout index for all switches in the fabric.
When a fabric is running mixed mode (switches are running Network OS 4.1.0 or earlier), the QSFP
breakout index is not displayed in the output on switches running Network OS versions earlier than
v4.1.0. In such instances, the neighbor port WWN (Nbr-WWN) is displayed as
XX:XX:XX:XX:XX:XX:XX:XX.
This command displays ISL details, including the breakout index of the interface if breakout mode
is configured on the source or neighbor interface.
Examples To display the multicast routing information for all ports in the switch:
switch# show fabric route multicast
