How To Change Existing VLAN IDs in Physical Exalogic Environments (Doc ID 2120490.1)

Last updated on APRIL 14, 2024

Applies to:

Oracle Exalogic Elastic Cloud Software
Oracle Exalogic Elastic Cloud X2-2 Hardware - Version X2 to X5 [Release X2 to X5]
Linux x86-64

Purpose

Network reconfiguration in customer’s data center may result in changes to VLAN IDs for networks provisioned on Exalogic. Such changes require reconfiguration on the InfiniBand NM2 Gateway switches on Exalogic. The VLANs provisioned on the switches must match those for the modified VLAN IDs and vNICs must be plumbed to the right VLANs.

This document describes a procedure to reconfigure NM2 Gateway Switches on Exalogic to accommodate the changed VLAN IDs.

NOTE: This procedure is applicable to Exalogic racks running Linux on bare metal (physical configuration) only, and does not apply to Virtual or Solaris environments.


The following shows the network traffic flow from the Exalogic rack to the customer’s client network:

Compute Nodes -> EOIB Network Interface -> NM2-GW -> 10Gb-Uplink(VLAN) -> 3 layer Switch(VLAN) -> Customer’s Client Network -> Other Hosts

This document provides a step-by-step procedure to reconfigure Exalogic to match the new VLAN IDs.
