To modify the switches for your environment:
- Download the switch configuration files from GitHub:
git clone https://github.com/dell-esg/openshift-bare-metal.git
- Modify the sample switch configuration files in <git clone dir>/containers/examples to match your VLAN and IP schemes.
The deployment uses untagged VLANs that use switchport access for nodes and tagged port channels for switch uplinks.
The deployment sample uses:
- VLAN_461 configured public network
- VLAN_34 configured for management network
- Single 100 GbE Mellanox X5 DP NIC in PCI slot 2
Note: The serial-port baud rate is 115200.
Note: Ethernet ports ens2f0 and ens2f1 in R640 servers are used in the rest of the document for CoreOS, p2p1, and p2p2 for Red Hat Enterprise Linux 7.x.
