BLADEOS 6.3 Application Guide

IGMP Group Capacity

BLADEOS 6.3 supports IGMP groups differently than earlier releases:

The GbESM now supports a maximum of 2048 IGMP entries, on a maximum of 1024 VLANs.

When the switch is in stacking mode, one IGMP entry is allocated for each unique join request, based on the combination of the port, VLAN, and IGMP group address. If multiple ports join the same IGMP group, they require separate IGMP entries, even if using the same VLAN.

In stand-alone (non-stacking) mode, one IGMP entry is allocated for each unique join request, based on the VLAN and IGMP group address only (regardless of the port). If multiple ports join the same IGMP group using the same VLAN, only a single IGMP entry is used.
