Configuring CAM size for an IPv4 multicast group

Configuring CAM size for an IPv4 multicast group
To configure the CAM size of an IPv4 multicast group, enter the following command.
Brocade(config)# system-max ipv4-mcast-cam
Syntax: [no] system-max [ipv4-mcast-cam]
By default, no system-max parameter is configured.
The ipv4-mcast-cam parameter allows you to specify the maximum CAM size you want for an IPv4
multicast group.
The decimal parameter specifies the range that is supported for configuring the CAM size. On the
Brocade NetIron XMR, the minimum value supported is 0, and the maximum value supported is
65536. The default value is 8192. On the Brocade MLX series, the minimum value supported is 0,
and the maximum value supported is 32768. The default value is 4096.
Upon configuration, the Brocade system will verify the input value with the amount of CAM
resources that are available. If the Brocade system is unable to allocate requested space, it will
display the following error message on the Brocade NetIron XMR and Brocade MLX series.
If there is not enough CAM resources available to change the cam-partition profile from IPv4 to
IPv6, the following message is displayed.
l2-metro-2 0 114688 8192
mpls-l3vpn-2 0 114688 8192
