Address Table Commands
78-20269-01 Command Line Interface Reference Guide
User Guidelines
Use the mac-group mode when using a Network Management System that uses a
MIB based on the multicast MAC address.
For each Forwarding Data Base (FDB) mode, use different CLI commands to
configure static entries for IPv6 multicast addresses in the FDB, as described in
the following table:
FDB mode
mac-group bridge multicast
address
ipv4-group bridge multicast ipv6
ip-address
ipv4-src-g bridge multicast ipv6
roup source group
The following table describes the actual data that is written to the Forwarding
Data Base (FDB) as a function of the MLD version that is used in the network:
FDB mode MLD version 1
mac-group MAC group
address
ipv4-group IP group address
ipv4-src-group (*)
(*) Note that (*,G) cannot be written to the FDB if the mode is ip-src-group. In that
case, no new FDB entry is created, but the port is added to the (S,G) entries (if they
exist) that belong to the requested group. If an application on the device requests
(*,G), the operating FDB mode is changed to ip-group.
You can execute the command before the VLAN is created.
Example
The following example configures the Multicast bridging mode as ip-group on
VLAN 2.
Console(config)#
interface vlan
Console(config-if)#
