Address Table Commands
Cisco Sx350 Ph. 2.2.5 Devices - Command Line Interface Reference Guide
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
bridge multicast address
mac-group
ipv6-group
bridge multicast ipv6
ip-address
ipv6-src-grou
bridge multicast ipv6 source
p
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
ipv6-group
IPv6 group
address
ipv6-src-group
(*)
(*) In ip-src-group mode a match is performed on 4 bytes of the multicast address
and 4 bytes of the source address. In the group address the last 4 bytes of the
address are checked for match. In the source address the last 3 bytes and 5th
from last bytes of the interface ID are examined.
(*) 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 an ip-group on
VLAN 2.
switchxxxxxx(config)#
