Usage Guidelines

For ICX 7850 and ICX 7550 devices, values are used from the forwarding profile and there is no option to change these values. When a new profile is selected, the values from the new profile are applied. Refer to the forwarding-profile command for more information.

The following IGMP snooping multicast cache (mcache) resource limits apply to RUCKUS devices:

  • ICX 7150 devices support up to 3072 IGMP snooping mcache entries. The default number of IGMP snooping mcache entries is 512.
  • ICX 7250 devices support 8192 IGMP snooping mcache entries.
  • ICX 7450 devices support 8192 IGMP snooping mcache entries.
  • ICX 7650 switches support 8192 IGMP snooping mcache entries.

The no form of the command restores the default maximum number of IGMP snooping mcache entries.

Examples

The following example sets the maximum number of IGMP snooping mcache entries supported on the device to 2000.
