I see a message YYYY-MM-DD HH:MM:SS+GMT TimeZone "Bridge loop detected for MAC XX:XX:XX:XX:XX:XX, mute interface T:T" 0 30201:7D in Event Log. What does it mean?

Solution

Overview

This is a event logged when the Bridge loop detection mechanism detects a possible loop originating from the MAC address XX:XX:XX:XX:XX:XX and causes the ProxySG to "mute" the interface T:T. Take note that certain probe mechanisms from the L4 Switch vendor may trigger this as well, depending on how the network topology is configured. For example, the NetworkExtreme Probe Protocol.
