HP 449298-001 manual Common management operations, Logging out of the CLI, Show mac-cache

Page 50

IGMP allows VC-Enet modules to monitor (snoop) the IP multicast membership activities and to 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 basically 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.

Configuring MAC cache failover settings

•To configure MAC Cache Failover Settings, use the set mac-cachecommand:

>set mac-cache enabled=true refresh=10

•To dispaly MAC Cache Failover Settings, use the show mac-cachecommand:

>show mac-cache

When a VC-Enet uplink that was previously in standby mode becomes active, it can take several minutes for external Ethernet switches to recognize that the c-Class server blades can now be reached on this newly-active connection. Enabling Fast MAC Cache Failover causes Virtual Connect to transmit Ethernet packets on newly-active links, which enables the external Ethernet switches to identify the new connection (and update their MAC caches appropriately.) This transmission sequence repeats a few times at the MAC refresh interval (5 seconds recommended) and completes in about 1 minute.

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.

Logging out of the CLI

To log out of the CLI, use the exit command:

>exit
