IMPORTANT: Be sure to set switches to allow MAC addresses to move from one port to
another without waiting for an expiration period or causing a lock out.
IGMP Snooping
The IGMP Snooping feature allows VC-Enet modules to monitor (snoop) the IGMP IP multicast membership
activities and configure hardware Layer 2 switching behavior of multicast traffic to optimize network
resource usage. Currently only IGMP v1 and v2 (RFC2236) are supported.
The IGMP Snooping idle timeout interval is set to 260 seconds by default. This value is the "Group
Membership Interval" value as specified by IGMP v2 specification (RFC2236). For optimum network
resource usage, set the interval to match the configuration on the customer network's multicast router
settings.

To access this screen, click the Stacking Links link under Fibre Channel Settings in the left VC Manager
navigation window.
This screen shows the current status of Virtual Connect Ethernet module stacking links. This screen is the
same as the stacking links screen used in the Network Setup Wizard.
For additional information on connecting stacking links, and stacking links in a multi-enclosure
environment, see the HP Virtual Connect for c-Class BladeSystem Setup and Installation Guide.
