IP Multicast Commands
config igmp snooping flood-list
config igmp snooping flood-list [<access profile> | none]
Description
Configures certain multicast addresses to be slow path flooded within the VLAN.
Syntax Description
Default
None.
Usage Guidelines
With this command, a user can configure certain multicast addresses to be slow path flooded within the
VLAN, which otherwise will be fast path forwarded according to IGMP and/or layer 3 multicast
protocol.
The specified access profile
<access profile>
should contain a list of addresses which will determine
if certain multicast streams are to be treated specially. Typically, if the switch receives a stream with
destination address which is in the
<access profile>
in 'permit' mode, that stream will be software
flooded and no hardware entry would be installed.
The specified access profile must be type IP address.
When adding an IP address into the access-profile, a 32-bit host address is recommended.
This feature is meant to solve the multicast connectivity problem for unknown destination addresses
within system reserved ranges. Specifically this feature was introduced to solve the problem of
recognizing certain stream as control packets.
NOTE
The switch will not validate any IP address in the access profile used in this command. Therefore,
slow-path flooding should be used only for streams which are very infrequent, such as control packets.
It should not be used for multicast data packets. This option overrides any default mechanism of
hardware forwarding (with respect to IGMP, PIM, or DVMRP) so it should be used with caution.
Slow path flooding will be done within the L2 VLAN only.
Use the
none
option to effectively disable slow path flooding.
You can use the
show ipconfig
command to see the configuration of slow path flooding. It will be
listed in the IGMP snooping section of the display.
access profile
Specifies an access profile with a list of multicast addresses to be handled.
The access profile must be type IP address.
none
Specifies no access profile is to be used.
