Appendix B. Switch VLAN configuration instructions

This topic describes the instructions that are needed to configure an IBM Cumulus switch VLAN.
The IBM Cumulus switch would be preconfigured from manufacturing with proper VLAN that includes the
following:
• Service/FSP/BMC VLAN
– Blue network - Bottom ports
– VLAN 101
• Management/Provisioning VLAN
– Yellow network - Top ports
– VLAN 102
• IBM Elastic Storage System 3200 special ports
– Ports 1 - 12
– Trunk ports
– Default routes traffic to management VLAN
– Packets with VLAN tag 101 routed to service network.
