11.3 Tag the Ethernet Connectors With a VLAN Identifier

To tag an Ethernet connector on the gateway switch with a VLAN identifier, you must run the createvlan command on the gateway switch that the VLAN will be associated with.

In this process, you are mapping the following:

• Ethernet connector on the Sun Network QDR InfiniBand Gateway Switch (0A-ETH-1 to 0A-ETH-4, and 1A-ETH-1 to 1A-ETH-4)

• VLAN ID (2 to 4094)

• InfiniBand partition key (0xFFFF)

Note:

Exalogic uses the default partition, and the partition key is 0xFFFF. You can associate multiple VLANs to a single Ethernet connector.

For example, you can associate VLAN identifiers 10 and 11 to the same Ethernet connector 1A-ETH-3.

To do so, run the createvlan command, as in the following example:

1. Log in to the gateway switch interface as root, and run the following commands:

   # createvlan 1A-ETH-3 -VLAN 10 -PKEY default

   Where 1A-ETH-3 is the Ethernet connector on the gateway switch, 10 is the VLAN identifier, and default is the partition key used in Exalogic.

   # createvlan 1A-ETH-3 -VLAN 11 -PKEY default

   Where 1A-ETH-3 is the Ethernet connector, 11 is the VLAN identifier, and default is the partition key used in Exalogic.

   If you are using Oracle Solaris compute nodes, you should also enable the connector for untagged traffic, by running the following command on the gateway switch:

   # createvlan 1A-ETH-3 -VLAN -1 -PKEY default

2. To verify, run the following command:

   # showvlan

   The following information is displayed:

   Connector/LAG    VLN    PKEY
   --------------   ---   -----
   1A-ETH-3           0    ffff
   1A-ETH-3          10    ffff
   1A-ETH-3          11    ffff
