33.1.7 ip multicast policy
Command: ip multicast policy <IPADDRESS/M> <IPADDRESS/M> cos <priority>
no ip multicast policy <IPADDRESS/M> <IPADDRESS/M> cos
Function: Configure multicast policy, the “no ip multicast policy <IPADDRESS/M>
<IPADDRESS/M> cos” command deletes it.
Parameter:
<IPADDRESS/M>: are multicast source address, mask length, destination
address, and mask length separately.
<priority>: specified priority, range from 0 to 7
Default: None
Command Mode: Global Mode
Usage Guide: The command configuration modifies to a specified value through the
switch matching priority of specified range multicast data packet, and the TOS is
specified to the same value simultaneously.Carefully, the packet transmitted in UNTAG
mode does not modify its priority.
Example: Switch(config)#ip multicast policy 10.1.1.0/24 225.1.1.0/24 cos 7
33.1.8 ip multicast source-control
Command: ip multicast source-control
no ip multicast source-control
Function: Configure to globally enable multicast source control, the “no ip multicast
source-control” command restores global multicast source control disabled.
Parameter: None
Default: Disabled
Command Mode: Global Mode
Usage Guide: The source control access-list applies to interface with only enabling
global multicast source control, and configure to disabled global multicast source control
without configuring source control access-list on every interface. After configuring the
command, multicast data received from every interface does not have matching
multicast source control list item, and then they will be thrown away by switches, namely
only multicast data matching to PERMIT can be received and forwarded.
Example: Switch(config)#ip multicast source-control
33.1.9 ip multicast source-control access-group
Command: ip multicast source-control access-group <5000-5099>
no ip multicast source-control access-group <5000-5099>
