Port Group Support
Port group feature is supported on IBP. Port Groups combine several ports into a group. Up to
10 groups are available for IBP. Each Port Group should contain internal server ports and/or
external ports. No network loops are allowed in the configuration. All external ports in the Port
Group form a trunk group.
Port Backup Support
Port Backup feature is supported on IBP for redundant uplink ports. Two aggregation groups
are created automatically as the Port Group is created. One of the aggregation groups are
defined as active aggregation link, and the other is defined as backup aggregation group. As
the active aggregation group is link down, the backup aggregation group will be activated for
transmittion. After the active aggregation group is link up again, the backup aggregation group
will be deactivated.
Failover Propogation Support
Blade Server has a dual-port network interface controller, and it realizes the redundant LAN
ports in case of using NIC management program with LAN teaming function. In order to
improve the switching time and realize the “rapid” fail-over of redundant LAN ports, Failover
Propogation feature is introduced in IBP for uplink ports to speed up the switching of the
redundant LAN ports.
Link Aggregation and LACP
LACP uses peer exchanges across links to determine, on an ongoing basis, the aggregation
capability of various links, and continuously provides the maximum level of aggregation
capability achievable between a given pair of systems. LACP automatically determines,
configures, binds and monitors the port binding to aggregators within the system.
BootP and DHCP Clients
DHCP enables additional setup parameters to be received from a network server upon system
startup. DHCP service is an on-going process. DHCP is an extension to BootP. For more
information on DHCP, see "Defining DHCP IP Interface Parameters".
