20 ADD IGMPSNOOPING ROUTERADDRESS Patch Release Note

Patch 86261-09 for Software Release 2.6.1

C613-10388-00 REV J

The maximum value that the MESSAGES parameter accepted for the

CREATE LOG OUTPUT command was different from the value that could

be set with the SET LOG OUTPUT command. The DESTROY LOG

OUTPUT command did not release the NVS memory that was reserved for

the output. These issues have been resolved.

The DHCP server did not take any action when it received a DHCP decline

packet. This was because the device only checked the ciaddr field in the

packet, and not the RequestedIPAddress option. This issue has been resolved.

This PCR introduces an enhancement that extends an issue that was

resolved in PCR 03890, in which switch port entries are only created for

special router multicast addresses. It is now possible to specify reserved

multicast addresses that will be treated as multicast packets from routers.

Use the following commands to configure this feature.

ADD IGMPSNOOPING ROUTERADDRESS

Syntax ADD IGMPSNOOPING ROUTERADDRESS=ipaddr[,...]

Description where:

• ipaddr is a reserved IP multicast address in dotted decimal notation.

This command adds reserved IP multicast addresses to the list of router

multicast addresses. The IP address specified must be within the range

224.0.0.1 to 224.0.0.255. This command is only valid if the IGMP snooping

router mode is set to IP with the SET IGMPSNOOPING ROUTERMODE

command.

SET IGMPSNOOPING ROUTERMODE

Syntax SET IGMPSNOOPING ROUTERMODE=

{ALL|DEFAULT|IP|MULTICASTROUTER|NONE}

Description This command sets the mode of operation for IGMP Snooping.

If ALL is specified, all reserved multicast addresses (i.e. 2240.0.1 to

224.0.0.255) are treated as router multicast addresses.

If DEFAULT is specified, the following addresses are treated as router

multicast addresses:

• IGMP Query: 224.0.0.1

• All routers on this subnet: 224.0.0.2

• DVMRP Routers: 224.0.0.4

• OSPFIGP all routers: 224.0.0.5

• OSPFIGP designated routers: 224.0.0.6

• RIP2 routers: 224.0.0.9
