HP Integrity BL870c i2 Server-Blade - Manual (Page 110)

Configuring the Virtual Connect domain using the CLI 110
>add server-port-map MyProfile:1 MyNetwork Uplinkset=MyUplinkset
Adding FC fabric connections to a server profile
To add a new FC SAN connection to an existing server profile, use the add fc-connection
command:
>add fc-connection MyProfile fabric=SAN_5
Configuring IGMP settings
To set Ethernet IGMP snooping properties, use the set igmp command:
> set igmp enabled=true timeout=30
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.
Assigning a server profile to device bay 1
To assign a server profile to a specific device bay, use the assign profile command:
>assign profile MyProfile enc0:1
When a profile is created and assigned to a multi-blade server, the profile is applied to all of the blades
in the multi-blade server. Therefore, the profile should contain enough Ethernet and Fibre Channel
connection entries for all of the ports on all of the blades in the multi-server.
Configuring MAC cache failover settings
• To configure MAC Cache Failover Settings, use the set mac-cache command:
>set mac-cache enabled=true refresh=10
• To display MAC Cache Failover Settings, use the show mac-cache command:
>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
