Enabling or disabling Layer 2 switching

By default, Brocade Layer 3 switches support Layer 2 switching. If you want to disable Layer 2 switching, you can do so globally or on individual ports, depending on the version of software your device is running.

NOTE
Consult your reseller or Brocade to understand the risks involved before disabling all Layer 2 switching operations.

Beginning with the Brocade FastIron release 8.0.50, when global route-only is enabled, the following syslogs appear to indicate the impact of the L2 functions already available on the ports.

  • On tagged ports and virtual Ethernet (VE) interfaces

ROUTE-ONLY: Only would cause L2 functions non-functional on %p Port, Part of VE/Tagged Interface

  • On generic attribute registration protocol (GARP) VLAN registration protocol (GVRP)-enabled ports

ROUTE-ONLY: Only would cause L2 functions non-functional on 1/1/15 Port, Part of VE/Tagged Interface

  • On virtual switch redundancy protocol (VSRP)-enabled ports

ROUTE-ONLY: Only would cause VSRP non-functional on 7th VLAN

  • On metro ring protocol (MRP)-enabled ports

ROUTE-ONLY: Global Route-Only would cause MRP non-functional on %dth VLAN
