•The default is 512 for most devices; for ICX 6430 devices the default is 256.
•FCX, FSX, ICX 6610, ICX 6450 and ICX 6650 devices support up to 8192 MLD snooping mcache entries.
•ICX 6430 devices support up to 2048 MLD snooping mcache entries.
•ICX 7750 routers support 3072 MLD snooping mcache entries; ICX 7750 switches support 8192 MLD snooping mcache entries.
•In Release 8.0.10a and later releases, ICX 7750 routers support 6144 MLD snooping mcache entries; ICX 7750 switches support 8192 MLD snooping mcache entries.
To define the maximum number of MLD snooping mcache entries, enter the
Syntax:[no] system-max mld-snoop-mcache num
he num variable is a value from 256 to 8192. The default is 512.
The configured number is the upper limit of an expandable database. Client memberships exceeding the group limits are not processed.
FCX, FSX, ICX 6610, ICX 6450, and ICX 6650 devices, ICX 7750 routers, and ICX 7750 switches support up to 8192 MLD snooping group addresses. ICX 6430 devices support up to 4096 MLD snooping group addresses.
To define the maximum number of multicast group addresses supported, enter the
The default for MLD snooping group addresses is 4096 for most devices; on ICX 6430 devices the default is 1024.

For all devices except the ICX 6430, The num variable is a value from 256 to 8192. The default is 4096.
For the ICX 6430, the num variable is a value from 256 to 4096. The default is 1024.
Configuring the global MLD mode
You can configure a Brocade device for either active or passive (default) MLD mode. If you specify an MLD mode for a VLAN, the MLD mode overrides the global setting.
•Active - In active MLD mode, a device actively sends out MLD queries to identify IPv6 multicast groups on the network, and makes entries in the MLD table based on the group membership reports it receives from the network.
•Passive - In passive MLD mode, the device forwards reports to the router ports which receive queries. MLD snooping in passive mode does not send queries, but does forward queries to the entire VLAN.
To globally set the MLD mode to active, enter the ipv6 multicast active command.
device(config)#ipv6 multicast active
Syntax: [no] ipv6 multicast [ active passive ]
