HP 1.10GB Virtual Connect Ethernet Module for c-Class BladeSystem - Manual (Page 74)

Network management 74
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.
Stacking Links screen
To access this screen, click the Stacking Links link under Fibre Channel Settings in the left VC Manager
navigation window.
Be sure to connect any Ethernet module stacking cables before running the network setup wizard.
IMPORTANT: For a Virtual Connect environment to operate properly, all Virtual Connect
Ethernet modules within the Virtual Connect domain must be interconnected with stacking links.
HP strongly recommends that redundancy be maintained in stacking links to ensure continued
connectivity of servers to the external networks.
This screen enables the user to determine whether all stacking cables are properly installed so that all Virtual
Connect Ethernet modules within the domain are interconnected:
• Connection Status indicates whether all of the Virtual Connect Ethernet modules within the domain are
interconnected with stacking cables and accessible. Lack of connection status to all Virtual Connect
Ethernet modules results in a critical alert.
o OK indicates that all modules are connected.
o Failed indicates that one or more modules are not connected properly. Check the cable
connections.
• Redundancy Status indicates whether all Virtual Connect Ethernet modules would remain fully
interconnected if a module or external cable was removed or failed. Horizontally-adjacent modules are
considered to have OK redundancy status because of the reliability of their internal link.
o OK indicates that redundant/reliable connections exist.
