ipv6-address—Specifies the source IPv6 address.

Default Configuration 

If the format is not specified, it defaults to mac (only if mac-multicast-address was 
entered).

If VLAN ID is not entered, entries for all VLANs are displayed.

If MAC or IP address is not supplied, entries for all addresses are displayed.

Command Mode

EXEC mode

User Guidelines

A MAC address can be displayed in IP format only if it is within the range 
0100.5e00.0000 through 0100.5e7f.ffff.

Multicast router ports (defined statically or discovered dynamically) are members 
in all MAC groups.

Ports that were defined via the 

 command 

are displayed in all forbidden MAC entries.

Changing the Multicast mode can move static Multicast addresses that are written 
in the device FDB to a shadow configuration because of FDB hash collisions.

Example

The following example displays bridge Multicast address information.
