802.1Q trunk links on BladeCenter HS20 with Red Hat Linux
In this section, we demonstrate how to configure BACS to set a NIC to receive multiple
VLANs through an 802.1Q trunk link on a BladeCenter HS20 running Red Hat AS 2.1. The
following configuration, which we discuss here as an example, is basically the same
configuration as BladeServer1 used in the previous topology examples in this chapter (except
for the IP addresses). For this configuration, we made the following assumptions:
򐂰 BladeServer1 uses the BASP software to create logical interfaces for VLANs 10, 15, 20,
and 25, and all IP configuration are performed on these logical interfaces (not on the
physical interfaces).
򐂰 Both ports use trunking (but not load balancing) through the Broadcom BASP software.
The first port will be configured for VLANs 10 and 15, the second port will be configured for
VLANs 20 and 25.
First port, VLAN 10 to CIGESM1 10.1.10.11 (default gateway = 10.1.10.254)
First port, VLAN 15 to CIGESM1 10.1.15.11
Second port, VLAN 20 to CIGESM2 10.1.20.11
Second port, VLAN 25 to CIGESM2 10.1.25.11
Note that the choice to use more than one default gateway (for example, one on each
VLAN or one on several VLANs) is up to the user. See the discussion about default
gateways on multihomed systems in Appendix A, “Hints and tips” on page 227.
Make two copies of the team-VLAN under the /etc/basp/sample directory and name each
team-toCIGESM1 and team-toCIGESM2. When you create two teams, you should make a
configuration script for each team. Modify the files as follows. Modified or added items are in
red italics.
