Error Message %MCAST-6-IGMP_RATE_LIMIT_DISABLE: IGMP: enabling Snooping on
Vlan([dec]), IGMP messages will not be rate limited
Explanation
After throttling the IGMP messages on the VLAN for a certain period, snooping is
reenabled after the user manually fixes the rate on the offending VLAN and reduces the CPU load.
Recommended Action No action is required.
Error Message %MCAST-6-IGMP_RATE_LIMIT_ENABLE: IGMP: Incoming IGMP message rate
exceeded max threshold([dec] pps), disabling Snooping on Vlan([dec]) with
Rate([dec] pps)
Explanation
The incoming rate of IGMP messages exceeded the maximum configured threshold.
Snooping will be disabled on all high-rate VLANs to lower the aggregate rate below the threshold
on all remaining VLANs.
Recommended Action Ease the CPU load by reducing the rate of IGMP messages on all high-rate
VLANs.

entry installation failed.
