Setting the Maximum Number of IGMP Mcache Entries and Group Addresses

You can change the maximum number of IGMP group addresses and the maximum number of IGMP mcache entries.
Note: For ICX 7850 and ICX 7550 devices, values are used from the forwarding profile. Refer to the forwarding-profile command in the RUCKUS FastIron Command Reference and the Configuration Fundamentals chapter in the RUCKUS FastIron Management Configuration Guide for more information.
  1. Enter global configuration mode. 
    device# configure terminal
  2. To set the maximum number of IGMP group addresses, use the system-max igmp-snoop-group-addr command. 
    device(config)# system-max igmp-snoop-group-addr 1600
    The configured number of IGMP group addresses is the upper limit of an expandable database. Client memberships exceeding the group limit are not processed.
  3. To change the maximum number of IGMP snooping cache entries supported on a device, use the system-max igmp-snoop-mcache command. 
    device(config)# system-max igmp-snoop-mcache 2000

The following example sets the maximum number of IGMP group addresses to 1600, and the maximum number of IGMP mcache entries to 2000. 

device# configure terminal
device(config)# system-max igmp-snoop-group-addr 1600
device(config)# system-max igmp-snoop-mcache 2000
