Control Bridge Considerations

Keep the following considerations in mind when configuring Campus Fabric:

  • To be used in a Campus Fabric configuration, an ICX 7650, ICX 7750, or ICX 7850 device must be running a router image.
  • An ICX 7650, ICX 7750, or ICX 7850 stack or a standalone ICX 7650, ICX 7750, or ICX 7850 device can be enabled as a CB.
  • A traditional stack that serves as a CB stack in a Campus Fabric domain can contain no more than 4 units.
  • A stack that serves as the CB can be configured in the same way as any traditional stack. A separate SPX interactive-setup utility is available for configuring an SPX domain when zero-touch provisioning is not appropriate.
  • ICX 7650 devices support SPX ports only on Module 1 or Module 2.
  • To be operational, a Campus Fabric configuration requires correct CB-PE SPX port or SPX LAG configuration.
  • If Spanning Tree Protocol (STP) is enabled on a CB, the CB must be reloaded for previous spanning tree configuration to be available.
