Configuring a switch VLAN

Configure an IBM® Cumulus switch VLAN for high-performance, low-latency Ethernet, or InfiniBand network.

Manufacturing preconfigured the IBM Cumulus switch with the following VLAN:
  • Service/FSP/BMC VLAN
    • Blue network - Bottom ports
    • VLAN 101
  • Management/Provisioning VLAN
    • Yellow network - Top ports
    • VLAN 102
  • Special ports
    • Ports 1 - 12
    • Trunk ports
    • Default routes traffic to management VLAN
    • Packets with VLAN tag 101 routed to service network

Adding management switches

If the customer is out of ports on a single management switch, then a second one can be used to extend VLANs.

Connect the existing switch (Switch 1) port 45 to the new switch (Switch 2) port 47, and Switch 1 port 46 to Switch 2 port 48. It extends both the management and service VLANs ports to the new switch.
