Enabling or Disabling IGMP Snooping
By default, IGMP snooping is globally enabled on the EtherSwitch HWIC. When globally enabled or
disabled, it is also enabled or disabled in all existing VLAN interfaces. By default, IGMP snooping is
enabled on all VLANs, but it can be enabled and disabled on a per-VLAN basis.
Global IGMP snooping overrides the per-VLAN IGMP snooping capability. If global snooping is
disabled, you cannot enable VLAN snooping. If global snooping is enabled, you can enable or disable
snooping on a VLAN basis.
Follow the steps below to globally enable IGMP snooping on the EtherSwitch HWIC.
