New Software Features in Release 12.1(11b)E2
New disable-snooping keyword for the mac-address-table static command that can be entered to
prevent multicast traffic addressed to a statically configured multicast MAC address from also being sent
to all multicast router ports in the same VLAN, regardless of the enable state of IGMP snooping, which
allows normal use of IGMP snooping to constrain multicast traffic to other ports.
With IGMP snooping enabled or disabled, all multicast traffic to a static MAC address configured with
the disable-snooping keyword is sent only to the static MAC address port and not to any multicast router
ports in the VLAN. Without the disable-snooping keyword, all multicast traffic to a static MAC address
is also sent to all multicast router ports in the VLAN. (CSCdw84943)
