Loop protection is a loop detection and prevention method which is independent of Spanning Tree Protocol (STP) and is not disabled when the switch is in switchport backup mode or port is in discarding state. The LoopProtect agent has a method to detect loops and take action based on the configuration by the user. In order to find loops in the system, a loop detection frame is sent out periodically on each interface that loop protection is enabled on. The frame carries broadcast destination MAC address, bridge MAC source address, OUI Extended EtherType 0x88b7 as well as information to specify the origins of the packet. When the switch receives a loop detection frame that originated from the same switch, then a loop is found. The switch errdisables the receiving interface to break the loop, until a timeout period has passed or it is manually reset.

In an MLAG setup, routing on a switch (MLAG peer) is possible using its own bridge/system MAC, VARP MAC or VRRP MAC.

MLAG currently checks for basic MLAG configuration to be consistent (e.g. domain id) before formation with the peer.

When MLAG peer link goes down, the secondary peer assumes the primary peer is down/dead, and takes over the primary
