Installation And Configuration - HP Integrity BL890c - i2 Server Manual

Figure 2-47 Server Blade profile with TWO Flex-10 NICs configured. Each NIC is connected to a vNet (PROD-A-
1 and PROD-A-2), the additional NICs are connected to other networks, which are also part of the Shared Uplink
Sets, VLAN-Trunk-1 and VLAN-Trunk-2 respectively. The VLAN-Trunks are connected, at 10Gb, to a network switch,
through Port X1 on VC module 1 and Port X1 on VC module 2, creating an Active/Active uplink.

Installation and configuration

Switch configuration
Appendices A and B provide a summary of the commands required to configure the switch in either a
Cisco IOS or a ProCurve network infrastructure. The configuration information provided in the appendices
assumes the following information:
•
The switch ports are configured as TRUNK ports to support VLANs 101, 102, 103, 104 and 105.
All frames will be forwarding to VC with VLAN tags.
•
When adding the additional uplinks to the SUS, the switch ports connected to Virtual Connect will
need to be configured for LACP and configured for the same Link Aggregation Group.
VC CLI commands
Many of the configuration settings within VC can also be accomplished via a CLI command set. In order to
connect to VC via a CLI, open an SSH connection to the IP address of the active VCM. Once logged in,
VC provides a CLI with help menus. Through this scenario the CLI commands to configure VC for each
setting will also be provided.
Configuring Fast MAC Cache Failover
•
When an uplink on a VC Ethernet Module 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 forces Virtual Connect to transmit Ethernet packets on newly
active links, which enables the external Ethernet switches to identify the new connection (and update
