Flexlink Configuration Notes and Considerations

  • A maximum of 32 Flexlink instances can be configured.
  • Flexlink is supported on LAG interfaces.
  • Flexlink is supported in a stacking configuration.

    Flexlink interfaces must be part of the same VLAN domain. The addition and deletion of Flexlink interfaces on the VLAN must be organized as a port pair.

  • The forwarding state of the Flexlink interfaces are controlled by the Flexlink feature, so other Layer2 features cannot co-exist on those interfaces. The following features cannot be enabled on Flexlink interfaces:
    • Spanning Tree protocol (STP)
    • Per-VLAN protocols (Metro Ring Protocol [MRP] and Virtual Switch Redundancy Protocol [VSRP])
    • Multiple VLAN Registration Protocol (MVRP)
    • Private VLAN (PVLAN)
    • Port MAC security (PMS)
    • Protected ports
    • Flexible Authentication
    • Loop detection
  • ACL configurations can be applied, but ingress or egress traffic on the backup link will not take effect.
