L2 Failover with Other Features

BLADEOS 6.5.2 Application Guide

L2 Failover works together with Link Aggregation Control Protocol (LACP) and with Spanning Tree Protocol (STP), as described below.

LACP

Link Aggregation Control Protocol allows the switch to form dynamic trunks. You can use the admin key to add up to two LACP trunks to a failover trigger using automatic monitoring. When you add an admin key to a trigger, any LACP trunk with that admin key becomes a member of the trigger.

Spanning Tree Protocol

If Spanning Tree Protocol (STP) is enabled on the ports in a failover trigger, the switch monitors the port STP state rather than the link state. A port failure results when STP is not in a Forwarding state (such as Listening, Learning, Blocking, or No Link). The switch automatically disables the appropriate control ports.

When the switch determines that ports in the trigger are in STP Forwarding state, then it automatically enables the appropriate control ports. The switch fails back to normal operation.

Configuration Guidelines

This section provides important information about configuring Layer 2 Failover.

Any specific failover trigger can monitor ports only, static trunks only, or LACP trunks only. The different types cannot be combined in the same trigger.

A maximum of 24 LACP keys can be added per trigger.

Port membership for different triggers should not overlap. Any specific port should be a member of only one trigger.
